An S6502 chassis provides -48V DC input for connection with external PoE power distribution unit.

Note:

The backplane, SRPU, power module and fan tray all are required components in S6502.

1.6.2 Backplane

The backplane mainly functions in:

Providing communication channels for signal exchange between cards. Providing support for card hot-swapping Auto-detecting the card type inserted at slots Leading in electric power for distributed supply to the system Leading in signal lines for monitoring the fan tray and power frame

1.6.3 Power Supplies



1-13

Note:

The S6502 supports either AC or DC input, but they cannot run concurrently. You can choose the specific type as needed. Although the system can operate normally when one power module is working, the S6502 still provides two slots for power modules, in attempt to support 1+1 redundancy. The power module on the S6502 is hot-swappable.

The AC power supply module and DC power supply module of an S6502 Ethernet switch meet the following requirements:

AC power module and DC power module have exactly the same dimensions and installation ports;

AC power module and DC power module have exactly the same type of output plug-in units located at the same position;

AC power module and DC power module cannot be both inserted in one S6502.

I. AC power module

For AC power supply, you must use AC power module and AC power socket.

Item AC power module

Rated voltage 100 VAC to 240 VAC.; 50 Hz or 60 Hz

Max voltage range 90 VAC to 264 VAC.; 50 Hz or 60 Hz

1.6.4 External PoE Power Supply

When connected to an external PoE power supply, the S6502 can supply power to remote PD devices, such as IP phone sets and WLAN access point hosts, through its card which support PoE function.

Figure 1-8 Appearance of an external PoE power supply

Note:

S6502 supports an external PoE power supply with up to 1500 W power output. A single PSE2500-A1 power supply module can provide output power of 1250 W with 100 VAC to 140 VAC input voltage, and two modules up to 2400 W output. Three power supply modules are required to provide output power of 2400 W if power supply redundancy is desired. When with 200 VAC to 240VAC input voltage, a single PSE2500-A1 power supply module can provide 2500 W output. Two power modules are required if power supply redundancy is desired.

1.6.5 Fan Tray

The fan tray is at the right side of an S6502 chassis, and directly connected to the backplane through a connector. The fan fault signals are summarized and transmitted from the backplane to the SRPU for further processing. The fan tray is hot-swappable.

Installation Manual Quidway S6502 Ethernet Switch Chapter 3 Installation Preparations


3-1

Chapter 3 Installation Preparations

3.1 Safety Information

To avoid damage to human body and devices, please read the following safety recommendations carefully before installing your S6502. The recommendations do not cover every possible hazardous condition.

3.1.1 General Recommendations

Turn OFF all powers and remove all power cords before opening the chassis. Keep the chassis clean and dust-free. Keep the chassis and installation tools away from walk areas. Do not wear loose clothing, jewelry (including ring and necklace etc.) or any other

things that could get caught by the chassis when you install and maintain the switch.

3.1.2 Electricity

Look carefully for possible hazards in your work area, such as ungrounded power extension cables, missing safety grounds, and moist floors.

Locate the emergency power-off switch in the room before installation. Shut the power off first when accident occurs.

Unplug all the power cords and external cables before moving the chassis. Better not maintain the equipment alone when it is powered on. After shut off a switch, always check and make sure it is powered off. Do not place the switch on a moist area and avoid liquid flowing into the switch.

3.1.3 Moving

The S6502 is rather big and heavy, so follow the recommendations below when moving them.

Turn off all powers and remove all the power cords before moving the chassis. Do not move the switch alone. Work with another person. Move the switch slowly and stably. Never move suddenly or twist your body. Move the switch at stable and consistent paces with your peer. Keep balance of

your body.



3-2

Caution:

Do not hold the power handlers, but the handles on the rear of the chassis, or put fingers into the vent of chassis when moving the switch. Since the power handler and vent have not been designed to bear the weight of the entire chassis, it may hurt the switch chassis or even your body when you move the switch by handling them.

3.1.4 Wearing an ESD Wrist Strap

To prevent the electric component from being damaged by the electrostatic discharge (ESD), take ESD measures for the area where the switch is located and pay attention to the following:

Always wear an ESD wrist strap when installing the components, especially the electric printed circuit boards, of the switch.

Take the edge of the circuit board. Do not touch the components or the electric printed circuit.

Take the following steps to use the ESD wrist strap.

Step 1: Put your hand through the wrist strap and wear it

Step 2: Strain and tighten the strap, ensure that it makes good contact with your skin.

Step 3: Insert it into the ESD wrist strap hole in the switch chassis or attach the alligator clips to the grounding screw of the chassis.

Step 4: Make sure the ESD wrist strap is well grounded.

Note:

The ESD wrist strap is shipped with the S6502. There is an ESD wrist strap hole on the left side of the S6502 power module. The grounding screw is located on the bottom right corner of the chassis rear.

Caution:

For safety consideration, check the resistance of the ESD wrist strap. The resistance between human body and the ground should be 1 to 10Mohm.



3-3

3.1.5 Laser

Some LPUs of S6502 have optical ports. In operating status, it is prohibited to stare into the open optical port because the laser emitted from it has very high power density and is harmful to your retina.

Caution:

Staring at the laser beam inside the fiber could hurt your eyes.

3.2 Examining Installation Site

S6502 can only be used indoors. To ensure that the switch works normally and expand its service life, the installation environment shall meet the requirements below.

3.2.1 Temperature/Humidity Requirements

To ensure the normal operation and service life of a switch, a certain level of temperature and humidity should be maintained in the equipment room. If the humidity in the equipment room is too high and for a long time, it may go bad insulated or even power leakage may occur. Sometimes, high humidity may result in material mechanical performance changing or metal parts rusted. If the relative humidity is too low, the captive screws may become loose due to the shrinkage of the insulation washers. Meanwhile, the electrostatic is likely to be produced in the dry environment, which will jeopardize the CMOS circuit of the switch. The higher the temperature, the greater the damage it will do on the switch. High temperature for a long time will speed up the aging process of the insulation materials, greatly lower the reliability of the switch and therefore affect its service life seriously.

3.2.2 Cleanness Requirements

Dust does serious harm to the normal operation of the switch. The indoor dust accumulated on the chassis can cause electrostatic adsorption, resulting in poor contact between connectors or metal contact points. This happens more frequently when the relative indoor humidity is low, which will not only shorten the service life of the switch, but also cause communication failures.

The required specifications on dust density and particle diameter in an equipment room are shown in the following table.



3-4

Table 3-1 Required specifications on dust density in an equipment room

Mechanical active material Unit Content

Dust particle particles/m³ ≤3 x 104 (No visible dust on desk in three days)

Note: Dust particle diameter ≥ 5µm

Except the requirements on dust, rigorous requirements on ingredient of salts, acids and sulfides of air in an equipment room are also set. These harmful gases will speed up the metal corrosion and the aging processes of certain parts. The equipment room should be protected from the invasion of harmful gases such as SO2, H2S, NO2, NH3 and Cl2, the value limits of which are shown in Table 3-2:

Table 3-2 Limits on harmful gas ingredients in an equipment room

Gas Max. (mg/m3)

SO2 0.2

H2S 0.006

NH3 0.05

Cl2 0.01

3.2.3 Anti-static Requirements

Any possible interference sources, no matter outside or inside the system, affect the switch in use may in a way of capacitance coupling, inductance coupling, radiation of electromagnetic wave, common impedance (including the grounding system) coupling or conducting line (power line, signaling line and transmission line etc.).Therefore, the following should be considered:

Adopt effective measures to protect the power supply system against the power grid interference.

Separate the working ground of the switch from the ground device of the power supply equipment or lightning-protection ground device as far as possible.

Keep the switch far away from the radio launcher, radar launcher, and high-frequency devices working in high currents.

If necessary, adopt electromagnetic shield.



3-5

3.2.4 Grounding Requirements

A good grounding system is the basis for a switch to work stably and reliably and the important guarantee of lightning protection, anti-interference and ESD. A switch should be provided with good grounding system.

3.2.5 Power Supply Requirements

The S6502 power system is in 1+1 redundancy, among which:

AC input voltage: 100 VAC to 240VAC, 47 Hz to 63 Hz Power output: 300W

3.3 Installation Planning

Since the S6502 is a kind of complex equipment, it is necessary to make a good plan and arrangement concerning installation position, networking measure, power supply and cabling before installing it.

3.3.1 Space Requirement

For better heat dissipation and equipment maintenance, it is recommended to keep the front and back of the switch more than 1 meters inclusive away from the walls or other devices. There can be other devices located beside the left and right of the switch. However, you shall keep the left and right of the switch more than 0.8 meters inclusive away from the walls. If the optional rack will be installed, the net height of equipment room should be more than 3 meters inclusive.

3.3.2 Rack-Mounting Requirements

Before rack-mounting a switch, make sure the rack meets the following requirements:

Better mount a switch in an open rack. However, if you mount a switch in a closed rack, make sure of good heat dissipation system.

Make sure the rack stands steadily enough to well support the switch and accessories.

Make sure that the switch fits the rack size. Leave enough spaces beside the left and right panels of the switch for chassis heat dissipation.

4.8.3 Connect Optical Fibers

I. Introduction

Before connecting the fibers, make sure the type of the connector and the fiber match that of the optical port.

Fiber connectors are indispensable passive components in optical fiber communication system. Their application enables the removable connection between optical channel,



4-10

which makes optical system debugging and maintenance more convenient and transit dispatching more flexible. Among multiple fiber connectors, only SC, LC, and MT-RJ will be introduced here.

MT-RJ fiber connector: It integrates two channels of light sources into a single fiber, which reduces the actual ports that are in use of a connector.

Figure 4-9 An MT-RJ connector

SC fiber connector

Figure 4-10 An SC connector

LC fiber connector

Figure 4-11 An LC connector

II. Connecting an optical fiber

Step 1: Remove the fiber cover and clean the fiber end.

Step 2: Remove the optical port cover of the switch. Insert one end of the fiber into the optical port of the switch.

Step 3: Connect the other end of the fiber to the corresponding device.



4-11

Caution:

When the optical port has not been connected with a fiber connector or its dustproof cover is open, there might be some invisible radiation emitted from the optical port. So do not stare into the optical port directly. Cover the optical port if there is no connector plugged in.

4.9 Recommendations on Cabling

4.9.1 For Table-Mounting

If the chassis of a switch stands alone, you do not have to care about the inside or outside cabinet cabling. All the port service cables can run along the left side of the chassis (cabling channel), and the chassis power cords can run upward or downward based on the specific conditions in the equipment room (lightning protection box, terminal bar etc).

4.9.2 Rack-Mounted Switch

For the switches are mounted in a 19-inch standard rack, the service cables can be bound to the cable binding rack at the left side of the chassis and be arranged to run on the cable rack or in the raised floor according to the situation in an exchange equipment room (whether the signal cable of the room is accessed from the cable rack on the top of the chassis or the cable channel under the floor.) Collect all the transit data signal cable connectors and locate them on the floor of the chassis instead of any places outside the chassis for fear of unexpected damage. The power cords run out of the rear left of the chassis and either on the cable rack or in the raised floor as near as possible based on the specific conditions in the equipment room (lightning protection box, terminal bar etc).

4.10 Cable Binding

4.10.1 Use of Labels

Correctly edit the label and paste it to a proper place on the bound cables.

4.10.2 Precautions for Binding Cables

Bind the cables straight in the cabinet. No twisting or bending.



4-12

Twisting

Bending

Twisting

Bending

Figure 4-12 Cable binding example I

The radius of the curve at which a cable is bent should be no less than twice of the cable’s diameter. At the point where a cable runs out of a connector, the radius of the curve at which the cable is bent should be no less than five times of its diameter.

Cables of different type (that is, power cord, signal cable, ground wire, etc.) should run and be bound separately in a cabinet. They cannot be bound together. If they are close to each other, you can cable them in a crossing way. For parallel cabling, the space between power cord and signal cable should be no less than 30mm;

The cable binding rack and cable channel inside and outside a cabinet should be smooth and stretch no sharp points.

The metal hole through which a cable runs should have a smooth and fully surface or an insulating bush;

Use the right type of ties to bind the cables. Do not bind any cables with tied ties. Huawei technologies provides the following types of ties: 100*2.5mm, 150*3.6mm, 300*3.6mm, 530*9mm, and 580*13mm;

Bind the cables with ties and cut the extra parts. Trim the cut and leave no sharp points. See the following figure:

Figure 4-13 Cable binding example II

Before bending the cables, bind them first. Mind that no tie binds the bended part of any cables, for fear of cable core breaking due to excessive stress. See the following figure.

Figure 4-14 Cable binding example III

The spare cables or excessive parts should be folded and bound and located at right places in a cabinet or on the cable channel. In the so-called right places, the running device will not be affected or damaged and the cables will not be damaged, either.

220V power cord and -48V power cord cannot be tied on the guides of any mobile components;

Keep excessive parts of power cords for those mobile components, such as ground wire of doors, to free the cables from possible stress. When installing these components, make sure the excessive cables will not touch heat source, sharp point, or keen edges. Use high temperature cables near the heat sources;

Chapter 6 Switch Monitoring and Maintenance

6.1 Switch Monitoring

Although the S6502 has passed the comprehensive and strict test before delivery, there might be some fault occurring due to improper installation. This chapter describes how to troubleshoot.

On the SRPU of the S6502, you can find the state LEDs of LPU, power supply, and fan and locate the faults accordingly.

6.1.1 Configuration System Troubleshooting

After the switch is powered on and the system is normal, the booting information will be displayed on the configuration terminal. If the configuration system has failed, the configuration terminal may display illegible characters or nothing at all.

1) No display on the terminal screen

After power on, if there is no information displayed on the terminal, check if:

The power system works normally. SRPU works normally. The console cable has been connected to the console port in the SRPU.

If there is no problem in the above checking, there might be some other faults as follows:

Serial port connected to the console cable is wrong. (The port in use is not the one set on the terminal.)

Configuration terminal parameter setting errors. (Parameter setting requirements: Set the baud rate to 9600, data bits to 8, parity check to none, stop bits to 1, flow control to none, and select VT100 as terminal emulation mode.)

There is something wrong with the console cable. 2) Illegible display on the terminal screen

If the configuration terminal displays illegible characters, the configuration terminal settings are likely to contain errors. Check the settings one by one. (Set the baud rate to 9600, data bits to 8, parity check to none, stop bits to 1, flow control to none, and select VT100 as terminal emulation mode.)

When resetting the card, if the ALM LED stays off, the card may have not been connected with the power source. Check if the card has been properly installed.

6.2 Hardware Maintenance

Caution:

The S6502 supports hot-swappable power modules. When installing or replacing a power module with the power on, consider the operation measures and safety with electricity. Do not touch any naked wire, terminal or any part of the product with a dangerous voltage label to avoid hurting human body.

6.2.1 Power Module Replacement

Step 1: Wear the ESD wrist strap and loosen the captive screw in the module to be replaced using the screwdriver.

Step 2: Pull the module to be replaced until it slides out of the slot.

Caution:

Because the S6502 power module is heavy, use both hands to pull it out. Hold the module in one palm and gently pull the handle with the other hand. Install a blank filler panel on the chassis for dust-proof and heat dissipation if you will not install another module in this position.



6-4

Step 3: Put the removed power module into the package.

Step 4: Take out a new power module from the package and make sure of the input mode.

Step 5: Hold the module in one palm and hold the handle with another hand. Align the module with the guides in the chassis and slide the module gently into the slot. Ensure the module matches well with the guides.

Caution:

Install the power module with caution. Note the direction of the panel. During the process of inserting, if the pin terminal springs up, the system will give an alarm and the pin cannot be seated into the hole. To avoid breaking or cranking the power terminals, if the power module has not been inserted in properly, you should slide it out and insert again.

Step 6: Fasten the captive screws (loosened in Step 1) to fix the power module on the chassis.

Caution:

If the captive screws cannot be fastened, the power module may not have been properly seated. Check it carefully.

6.3 BOOTROM and Host Software Loading

6.3.1 Introduction to Loading Approaches

This chapter introduces how to load BOOTROM and host software.

You can load the software remotely or locally via commands using:

FTP TFTP

You can load the software locally via Boot Menu using:

XModem via console port TFTP via Ethernet port FTP via Ethernet port



6-7

Note:

Please note that the BOOTROM version must match the host software version when BOOTROM and host software are being loaded. It is not recommended to load BOOTROM program frequently, BOOTROM program loading is allowed only when the host software to be loaded does not match the existing BOOTROM version.

Using Boot Menu can only load the SRPU BOOTROM program and host software. To load LPU BOOTROM, you must use the command line.

6.3.2 Loading Software Locally via Boot Menu

If your terminal is directly connected to the switch, you can load BOOTROM and host software locally.

Before proceeding to load the software, make sure that your terminal is correctly connected to the switch.

Note:

The steps that you should take to load BOOTROM program and host software are the same, except that in a BOOTROM program loading process you need to press <Ctrl +U> and <Enter> after accessing the BOOTROM menu and will view a different prompt message. BOOTROM loading steps are described below as an example.

I. Boot Menu

II. Loading software from console port using XModem

1) Introduction to XModem

XModem is a file transfer protocol widely used due to its simplicity and good functions. XModem transfers files via the console port, supporting data packets of 128 bytes and 1KB. With respect to reliability, it supports checksum, CRC, and error packet retransmission mechanism. Normally, the maximum number of retransmission attempts is ten.

XModem transmission is completed by the receiving program and sending program. The receiving program initiates packet checking method negotiation by sending the negotiation character. If the negotiation passes, the sending program starts packet transmission. Upon the receipt of a complete packet, the receiving program checks it using the agreed-upon checking method. If the check succeeds, the receiving program sends an acknowledgement character; if the check fails, it sends a reject character. Upon the receipt of the acknowledgement, the sending program continues to send the next packet; upon the receipt of the reject, it retransmits the packet.

2) Loading SRPU BOOTROM

Follow these steps to download the BOOTROM program:

Step 1: Press <Ctrl+U> and <Enter> in Boot Menu displayed in the section “I. Boot ” to access the BOOTROM loading menu shown below:

III. Loading software from Ethernet port using TFTP

1) Introduction to TFTP

Trivial File Transfer Protocol is a TCP/IP protocol used for file transmission between clients and servers. It uses UDP to provide unreliable data stream transfer service.


Step 1: Connect the switch to the PC from where the file is to be downloaded, via the 10/100Base-TX interface for loading. The IP address of the PC is required. At the same time, the switch is connected to a PC (which can be the same one as that holding the file for downloading) via the console port.

Step 2: Run the TFTP Server program on the PC connected to the Ethernet port, and specify the path for program loading.

Caution:

TFTP Server program is not shipped with the Quidway series switches. When loading BOOTROM and host software, you must use a crossover cable to

connect to the Ethernet port for upgrading.

Follow these steps to download the host software of the switch.









6-16

Select <1>. The subsequent steps are the same as those for loading BOOTROM, except for the displayed prompt messages.

IV. Loading Software from Ethernet Port Using FTP

1) Introduction to FTP

A switch can be used via Ethernet port as an FTP server or a client to provide another approach for software loading and file configuration. An example of a switch being used as an FTP client is given below.


Step 1: Connect the switch to the PC from where the file is to be downloaded, via the 10/100Base-TX interface on SRPU for loading. The IP address of the PC is required. At the same time, the switch is externally connected to a PC (that can be the same one as that the downloaded file is located) via a console port.

Step 2: Run the FTP Server program on the PC that is connected to the Ethernet port, and specify the path for program loading.

Caution:

FTP Server program is not shipped with the Quidway series switches. When loading BOOTROM and host software, you must use a crossover cable to

connect to the Ethernet port for upgrading.

Step 3: Run terminal emulation program on the PC connected to the console port. Start the switch, access Boot Menu, and then enter download protocol menu.

To download the BOOTROM program, press <Ctrl+U> and <Enter> to access the menu for BOOTROM downloading when the system displays: ”Enter your choice (0-5):”







Enter your choice(0-3): 2



6-17

Step 4: In the download protocol menu, type <2> to select FTP protocol to download BOOTROM and host software. Press <Enter>. The system displays the following information:

Load File name

Switch IP address

Server IP address

FTP User Name

FTP User Password

Step 5: Enter the FTP parameter values. The system displays the following information:

Are you sure to update SRPU bootrom? Yes or No(Y/N)

Step 6: Enter <Y> to start file downloading and <N> to return to the program downloading menu. Suppose you enter <Y>. The system starts program downloading and upon its completion, starts writing to Flash. The system displays the following information after completing the writing operation:

Prepare for loading...OK!

Loading....................................................done!







Follow these steps to download the host software:







You can select a different protocol to download host software.

The subsequent steps are the same as those for loading the BOOTROM program, except for the displayed prompt messages.

6.3.3 Loading Software Remotely and Locally via Commands

If your terminal is connected to the switch by a network, you can load BOOTROM and host software remotely via commands which can also be used in local software loading.



6-18

I. Loading by FTP

Run FTP Server on a local PC, provided you have configured username and password and have set the correct file directory. Suppose the IP address of the PC is 10.10.110.1. Log onto the switch via Telnet or the console port, to send the host program to the switch using FTP. Connect the PC and switch with a crossover cable if your terminal is connected to the switch via console port locally.

Note:

The S6502 supports dual image booting, that is, usually the switch boots with the main image (i.e. the primary file), but it uses the backup image (i.e. the backup file) when the primary one is in error. Refer to 6.3.4 Booting the Switch with Dual Images for details. The S6502 also supports the upgrade of combined BOOTROM file, that is, upgrading the BOOTROM of all boards using one combined BOOTROM file. Refer to 6.3.5 Loading Combined BOOTROM File for details.

Suppose that the main boot file is SWITCH002.app; the active host software is SWITCH001.app; the LPU BOOTROM program is LPUbtm.app; LPU occupies slot 3 and SRPU occupies slot 0. You can follow these steps after logging onto the switch.

Step 1: Download the software to the switch using FTP.

<Quidway> ftp 10.10.110.1

Trying ...

Press CTRL+K to abort

Connected.

[ftp] get Switchbtm.app Switchbtm.app

[ftp] bye

Note:

You may also download two copies of host software, with one as the primary and the other as the backup.



6-19

Step 2: Load BOOTROM.

<Quidway> boot bootrom Switchbtm.app

please wait ...

Bootrom is updated!

Step 3: Load the host software.

Load the primary file

<Quidway> boot boot-loader primary SWITCH002.app

Load the backup file

<Quidway> boot boot-loader backup SWITCH001.app

<Quidway> display boot-loader

The primary app to boot of board 0 at the next time is: flash:/SWITCH002.app

The backup app to boot of board 0 is: flash:/SWITCH001.app

The app to boot of board 0 at this time is: flash:/SWITCH001.app

<Quidway> reboot (Make sure that you have saved other configurations before rebooting, otherwise, they might not survive a reboot.)

BOOTROM and host software loading is complete now. Note that you must reboot the switch to validate host software downloading. If Flash memory space is not enough, you can delete some of the program files in Flash after completing the BOOTROM loading. (You are recommended to delete the host program that is no longer in use.) Then upload the host program to the switch using FTP. Note that power-off must be prevented during loading process.

II. Loading by TFTP

Using TFTP is similar to using FTP in remote and local loading via commands. The only difference is that it is TFTP that you use when loading software to the switch. In this case, the switch can only be used as a TFTP client to download the software to its Flash memory from the TFTP server. The remaining steps after downloading are the same as those with remote loading using FTP.

6.3.4 Booting the Switch with Dual Images

The S6502 supports dual image booting: usually the switch boots with the main image (i.e. the primary file), but it uses the backup image (i.e. the backup file) when the main image is in error. BOOTROM 400 or above version is required to support dual image booting.

Refer to 6.3.3 Loading Software Remotely and Locally via Commands for loading dual images to the switch using commands. The following introduces the setting of dual images in Boot menu.

Step 1: Enter Boot menu.



6-20

BOOT MENU

1. Download application file to flash

2. Select application file to boot

3. Display all files in flash

4. Delete file from flash

5. Modify bootrom password

0. Reboot


Step 2: Enter <2> to turn to the menu for choosing the active booting file.

File Number File Size(bytes) File Name

========================================================

1. 4 snmpboots

2. 1972 SWITCH100.cfg

3. 1012 taskswitch.log

4. 631736 Btm400.btm

5. 199696 8241btm.app

6. 2427 vrpcfg.txt

7. 6048565 SWITCH200.app

8(*). 5639172 SWITCH000.app

9(-). 203460 SWITCH100.app

The current application file is :SWITCH000.app

The backup application file is : SWITCH100.app

Free Space : 471040 bytes

The system shows all the files in the flash memory, where the one with an asterisk (*) is the primary file and the one with a hyphen (-) is the backup file.

Step 3: Reset the primary and backup files.

Set the primary file.

Enter the serial number of the desired primary file when the terminal shows the following information:

Please input the primary application file number to boot :9

Press <Enter> and the system displays the primary file name you have chosen. Enter <Y> to acknowledge and <N> to reset.

The primary file you selected is SWITCH100.app, are you sure? Yes or No(Y/N):Y

Enter <Y> (as an example) and the terminal shows this information:

On reboot, SWITCH100.app will become the default primary application file to

boot!

This means the primary file has been set successfully.

Set the backup file



6-21

You can set the backup file in almost the same way as setting the primary file. The terminal shows the following information in this case:

Please input the backup application file number :7

The file you selected is SWITCH200.app, are you sure? Yes or No(Y/N)y

On reboot,SWITCH200.app will become the backup application file to boot!

Step 3: Decide if to run the primary file immediately. Enter <Y> and the system begins to reboot.

Do you want to run SWITCH100.app now?Yes or No(Y/N)?Y

press Ctrl+B to enter Boot Menu... 5

Auto-booting....................

These may occur in your system booting:

1) The primary file is correct and the system boots with the primary file. 2) A fault occurs when the system boots with the primary file, so it boots with the

backup file. 3) Both the primary and backup files are in error, so the system chooses randomly an

application file for booting. 4) The system stops choosing boot file if it fails when booting with a random

application file. Then it just supposes that the file system is unavailable or no correct booting file is available.

Note:

If you specify only the primary file, and set no backup file, the system boots with the primary file. If the primary file is in error, the system randomly chooses an application file for booting.

If you specify only the backup file, and set no primary file, the system boots with the backup file.

If you specify neither the primary file nor the backup file, the system randomly chooses an application file for booting.

6.3.5 Loading Combined BOOTROM File

Since the S6502 supports multiple types of cards of and these cards use different versions of BOOTROM, you are required to use the appropriate BOOTROM file when upgrading the BOOTROM of a card. The upgrading fails if the BOOTROM file does match the card.

To avoid the inconvenience caused by different BOOTROM files in upgrading, in BOOTROM version 400 and the following BOOTROM, we combine the BOOTROM files of all cards (including LPU and SRPU) into one, that is, the BOOTROM released in



6-22

the future will have only one file *.BTM, which can be used to upgrade BOOTROM of all cards.

I. Precautions in upgrading using combined BOOTROM file

Note the following items upon upgrading using the combined BOOTROM file:

1) Upgrading BOOTROM version 400 or higher

BOOTROM version 400 or higher can be upgraded by a single BOOTROM file or the combined BOOTROM file. And you are recommended to use the combined one.

2) The host software is required to support the combined BOOTROM file

Using the combined file to upgrade BOOTROM of cards requires the support of the host software to the combined BOOTROM file. Host software of the latest version recognizes the single file and the combined file automatically. The versions of the host software that support upgrading by combined file are: version 052 and higher, version 1001 and higher.

3) Upgrading BOOTROM version 360 or lower

BOOTROM version 360 and lower can not recognize the combined BOOTROM file, so you can upgrade them by using single files. If you intend to upgrade them by using the combined file, you need to upgrade BOOTROM online through the command line on the host software that supports the combined file, and you cannot upgrade the combined BOOTROM file by using Boot Menu; otherwise, the system prompts you that there are upgrading file errors and the BOOTROM cannot be upgraded.

4) Naming the combined BOOTROM file

For differentiation convenience, the single BOOTROM file is named *.app, and the combined BOOTROM file is named *.btm.

Note:

If the host software does not support the combined BOOTROM file and the upgrading fails, try to upgrade BOOTROM of every card by using single BOOTROM files.

II. Examples of upgrading using combined BOOTROM file

Predefined conditions: the SRPU on slot 0 of the S6502 is LS81P12TE; the LPU on slot 1 is LS81FT48A; the combined BOOTROM file is S6502btm.btm; the version of the host software which supports the combined BOOTROM file is S6502.app. Both the online upgrading of command line and the upgrading through Boot Menu use FTP mode.

1) Upgrading BOOTROM Version 306 or Lower



6-23

Note:

You can use either the command line (see this example) or Boot Menu to upgrade the host software to the version that supports the combined BOOTROM file, and upgrade BOOTROM of all cards using the combined BOOTROM file through command line.

You also can upgrade the BOOTROM of every card by using single BOOTROM files through command line and Boot Menu.

Step 1: Download the host software that supports the combined BOOTROM file and the combined BOOTROM file on the switch using FTP.


[ftp] get S6502.app S6502.app

[ftp] get S6502btm.btm S6502btm.btm

[ftp] bye

Step 2: Specify S6502.app as the application software applied by the switch during the next boot.

<Quidway> boot boot-loader primary S6502.app

Step 3: Reboot the switch to make the S6502.app effective.

<Quidway> reboot

Step 4: Upgrade the BOOTROM of the LPU and SRPU using the combined file.

<Quidway> boot bootrom S6502btm.btm slot 0 1

please wait ...

Bootrom is updated!

After the above operation, you can complete the upgrading of the BOOTROM.

2) Upgrading version 400 or higher

BOOTROM version 400 and higher can recognize the combined BOOTROM file automatically. The host software is also required to support the combined BOOTROM file if you want to upgrade the BOOTROM of all cards.

Online upgrading through command line

The way of upgrading through command line is omitted here since it is the same as that described in the section Upgrading BOOTROM Version 306 or Lower.

Upgrading the combined BOOTROM through Boot Menu



6-24

Note:

Using Boot Menu, you can only upgrade the BOOTROM of an SRPU. And use the command line if you need to upgrade the BOOTROM of the LPU.

Step 1: After entering Boot Menu, the system prompts you: “Enter your choice (0-5):”.To enter the BOOTROM upgrading menu, press <Ctrl + U> and <Enter>.






Step 2: Type <2> to choose upgrading through FTP, press <Enter>, and begin to set the related parameters of FTP protocol.

Load File name :S6502btm.btm

Switch IP address :1.1.1.3

Server IP address :1.1.1.2

FTP User Name :6506

FTP User Password :123

Are you sure you want update FAB64 bootrom? Yes or No(Y/N)y

Step 3: Enter <Y>, and the system begins to download files.

Prepare for loading....OK!

Loading...................................................................

......

....................................................................done!

The file is an union files, file name is S6502btm.btm

There are 3 files in this packet

Update-file number is 1st name is SRPU400.app

FAB64 bootrom is updating now......

Get flash Type......FLASH_AMD29LV040B




3) Examples of upgrading using a single BOOTROM file



6-25

Caution:

Ensure to use the appropriate version of BOOTROM file during upgrading the BOOTROM of every card by single BOOTROM files; otherwise, the switch crashes.

You can choose either the command line or Boot Menu mode to upgrade by using single BOOTROM file. You are recommended to use the command line mode to complete the online upgrading. Here takes the command line mode as an example.

Predefined conditions: the card on slot 0 of the S6502 is LS81SRPUA, and its corresponding BOOTROM file is SRPUbtm.app; the card LS81FT48A is on slot 1, and its corresponding BOOTROM file is LPUbtm.app. This example introduces online upgrading through FTP mode; you can also upgrade BOOTROM through the TFTP mode, which is omitted here.

Follow these steps to upgrade:

Step 1: Download single BOOTROM file to the switch through FTP.


[ftp] get SRPUbtm.app SRPUbtm.app

[ftp] get LPUbtm.app LPUbtm.app

[ftp] bye

Step 2: Load single BOOTROM files to every card.

<Quidway> boot bootrom SRPUbtm.app slot 0

<Quidway> boot bootrom LPUbtm.app slot 1

After the above operation, you can complete the upgrading of the BOOTROM on every card.

6.3.6 Dealing with Failed Loading

If loading fails, the original version will remain in the system.

In this case, check that the physical ports are correctly and well connected. If they are not, reconnect them correctly and restart loading procedures.

If there are no problems with the physical connections, carefully check information about the loading procedures for input errors on the HyperTerminal.

When using XModem, check that you have reset the baud rate of the HyperTerminal to 9600bps after loading the software with a baud rate other than 9600 bps;

1) When using TFTP, check that you have provided: Correct server and switch IP addresses; Correct name of the software to be loaded;



6-26

Correct path for TFTP Server to operate. 2) When using FTP, check that you have provided:

Correct server and switch IP addresses; Correct name of the software to be loaded; Correct username and password.

If loading fails when there are neither physical connection problems nor input errors, contact the local agents of Huawei Technologies for help.

6.3.7 Dealing with Lost Password

Please contact the local agent of Huawei Technologies if the BOOTROM password or user password of the switch is lost.

Installation Manual Quidway S6502 Ethernet Switch Appendix A Lightning Protection of the Switch

Appendix A Lightning Protection of the Switch

A.1 Installation of Lightning Arrester for AC Power (Socket Strip with Lightning Protection)

Caution:

Lightning arrester will not be shipped with the switch. You should purchase it by yourself if needed.

If an outdoor AC power cord should be directly led to the switch, please serially connect the lightning arrester for AC power (Socket Strip with Lightning Protection) before you plug AC power cord into the switch, thus to prevent the possible damage to the switch due to lightning strike. You can use cable clips and screws to fasten the lightning arrester for AC power on the cabinet, workbench or the wall of equipment room.

Mainboard

Grounding and polarity indicator (red) :On means that the lines are wrongly connected(either the ground wire is not well connected, or the live and zero lines are wrongly connected).Please check the power supply circuit.

Power switchNormal operation indicator (green): On means that the arrester works normally. Otherwise, it means that the protection circuit has been damaged.

Multipurpose power socket, connected to the deviceprotected by the arrester

Power socket (complied with IEC standard), connected to the power supply of the equipment roomthrough power cord

Overload auto protector,which can be manually reset.

Figure A-1 Diagram of lightning arrester



A-2

Caution:

Make sure that the arrester is well grounded before using the lightning arrester for power.

After inserting AC power cord plug of switch into the socket of lightning arrester, if the green LED is on and the red LED does not alarm, it means that the lightning arrester of power is running and the function of lightning protection has taken effect.

Pay adequate attention if the red LED is on. You should correctly locate the problem, whether it is caused because the ground wire of the arrester is not well grounded or because the live and zero wires are connected in reverse direction. You may check that in the following way. When the red LED is on, use a multimeter to examine polarity at the power socket of the arrester. If it is same to that of the power socket in the equipment room, it means that arrester is not well grounded. If it is adverse to that of the power socket in the equipment room, it means that the power socket of the arrester is set to the reverse polarity. In this case, you should open the power socket of arrester to correct polarity. After that, if the red LED still alarms, it means that the arrester is not well grounded yet.

A.2 Installation of Lightning Arrester for Network Port

Note:

Lightning arrester for network port is specially designed for the Ethernet port of 10/100M electrical interface (RJ-45 connector is adopted in this case).

Caution:

Lightning arrester for network port will not be provided along with the switch, and you should purchase it by yourself if needed.

6If an outdoor network cable should be led to the switch, please serially connect the lightning arrester for network port before you plug this cable into the interface on the switch, in case of the possibility that the switch may be damaged due to lightning strike.

I. Required tools

Phillips screwdriver or Flat-blade screwdriver



A-3

Multimeter Tilted wire cutter

II. Installation procedure

Step 1: Tear the protection paper at one side of the double faced adhesive tape apart from the tape, and stick the tape on the surface of the arrester. Tear the protection paper at another side apart from the tape, and stick the arrester onto the chassis of the switch. The arrester should be attached on the chassis as close to the grounding screw as possible.

Step 2: According to the distance to the grounding screw of the switch, cut the ground wire of the arrester, and securely tightening its ground wire to the grounding screw of the switch.

Step 3: Use the multimeter to measure whether the ground wire of the arrester contacts well with the grounding screw of chassis.

Step 4: According to the instruction of arrester for network port, connect the arrester with switch by the cables (be carefully with the cable direction. Outdoor network cable should be inserted into the arrester‘s IN end, and the cable connected to the switch should be inserted into the arrester’s OUT end). When you do that, observe whether the arrester indicators normally display.

Note:

The instruction of lightning arrester for network port contains the technical specifications, installation and maintenance guide of the arrester. Please carefully read it before installing the arrester.

Step 5: Use the nylon ties to bundle the cables neatly.

III. Installation precautions

Fully consider the following items in the installation process, otherwise, the performance of the lightning arrester for network port will be affected:

Lightning arrester for network port is installed in reverse direction. In practice, the “IN” end should be connected to the outdoor network cable and the “OUT” end to the network port on the switch.

Lightning arrester for the network port is not well grounded. The ground wire for the arrester should be as short as possible, so to ensure its good contact with the grounding screw of the switch. After the connection, use the multimeter to confirm that.

The lightning arrester for the network port is not installed completely. If the switch has more than one network ports to interconnect with other devices via cables outdoor, you should install lightning arresters for all these network ports for protection.
