3.1.2 Cleaning the Fan Frame

Context

During the operation of the device, the fan, the controlling circuit board and some other parts ofthe fan frame absorb the dust in the air. When a certain amount of dust is accumulated, theoperation stability of the fan frame will be affected. In addition, the accumulated dust becomesthe pollution source of the service cabinet and hence threats the stable operation of the device.To ensure the stable operation of the device, the maintenance personnel must clean all the fanframes every one years.

Precautions

DANGERDo not put your hands into the running fans!



3-3

CAUTIONThe operation must be completed within five minutes; otherwise, the safety and stability of thedevice will be severely affected because of the high temperature.

Toolsl ESD-preventive wrist strap or ESD-preventive gloves

l Philips Screwdriver

Procedure

Step 1 Clean the spare fan frame.

Clean the fan, controlling circuit board and other parts of the spare fan frame with clean cottonpledget, antistatic soft brush and vacuum cleaner. There should be no dust on the fan frame aftercleaning.

Step 2 Replace the fan frame to be cleaned.1. Check the position of the fan module to be cleaned.

Before removing a fan module that is to be replaced, check the position of the fan module,for example, the cabinet and chassis where the fan module is installed. Then, find out thefan module to be replaced in the chassis and attach a label to the panel to identify the fanmodule.

2. Wear the ESD-preventive wrist strap and connect the grounding terminal to the ESD jackon the rack.

3. Remove the fan module to be replaced from the chassis.

a. Loosen the four captive screws on both sides of the fan module with a crossscrewdriver, as shown in Figure 3-3 ①.

b. Grasp the handles on the two sides of the fan module and pull out the fan module, asshown in Figure 3-3 ②.

Figure 3-3 Removing a fan module


Routine Maintenance


Issue 03 (2009-09-20)

4. Locate the spare fan module into the chassis.

a. Grasp the handles on the two sides of the fan module and push the fan module intothe chassis, as shown in Figure 3-4 ①. When you push the fan module, align thelocating holes on the panel of the fan module with the bolts on the chassis. Push thefan module gently until the panel of the fan module touches the two sides of the chassis.

b. Tighten the captive screws clockwise with a cross screwdriver to secure the fan modulein the chassis, as shown in Figure 3-4 ②.

Figure 3-4 Installing a fan module

5. Verify the function of the new fan module.

In normal situations, after a new fan module is inserted into the chassis, the fansimmediately start to operate to blow air into the chassis. In this case, you can check whetherthe fan module functions normally as follows:

l If the STATUS indicator on the panel of the fan module is green and blinks at thefrequency of 0.5 Hz, it indicates that the fan module runs normally. If the indicator isred, it indicates that the fan module is abnormal.

l Run the display fan command to view the running status of the new fan module. If theoutput is displayed as follows, it indicates that the new fan module works normally.Take the S9312 for example:

<Quidway> display fan------------------------------------------------------------- FanId FanNum present register Speed MODE------------------------------------------------------------- 17 [1-0] YES YES 100% AUTO 18 [1-0] YES YES 100% AUTO 19 [1-0] YES YES 100% AUTO 20 [1-0] NO NO 0% AUTO

The preceding output information indicates that the fan module returns to the normal state.If the fan module is still abnormal, contact the Huawei local office for timely technicalsupport.

Step 3 Clean the replaced fan frame.

Clean the fan, controlling circuit board, and other parts of the spare fan frame with clean cottonpledget, antistatic soft brush, and vacuum cleaner. This fan frame is used as the spare one aftercleaning.

3.1.3 Cleaning the Boards

ContextDuring the operation of the device, dust accumulates on the boards because of air convection inthe process of heat dissipation. More dust accumulates on boards if the air is not clean and therelative humidity is low. When a large amount of dust is accumulated, the heat dissipation andthe electric insulation of boards are affected. This thus threatens the stable operation of thedevice.

To ensure the stable operation of the device, the maintenance personnel must clean all the boardsevery two years.

Precautions

WARNINGl Take ESD preventive measures during the whole process of routine maintenance. For

example, perform operations on an antistatic workbench and wear antistatic clothes and wriststraps.

l Use the detergent that conforms to the industry standard; otherwise, the board may bedamaged.

CAUTIONRemoving boards that are in service may affect the operation of services. Therefore, clean theboards when traffic is low, for example, between 2:00 a.m. and 4:00 a.m.

Procedure

Step 1 Prepare spare boards.

You must prepare a spare board for each board in the cabinet before you clean all the boards.

Step 2 Replace boards.

Replace a board with the spare board. You can start removing the dust from the board only whenthe spare one is running normally.

For details about how to replace boards, see Quidway S9300 Terabit Routing Switch PartsReplacement.

Step 3 Remove dust.

The process of cleaning the boards should be such that the physical attributes and electricalattributes of the boards are protected. The two ways to clean dust are as follows:l Using the vacuum


Routine Maintenance


Issue 03 (2009-09-20)

Brush dust off the board surface with a clean and dry antistatic soft brush and align the dustintake of a vacuum with the brush. In this case, dust is removed immediately when it isbrushed off.This method features simple operation and low cost. But it is difficult to remove harmful gasthat is adsorbed on the board surface.

l Using the detergentUse the anhydrous, erosion-free, non-conductive, and highly volatile detergent such asIsopropyl Alcohol (IPA) to remove dust from boards.

CAUTIONIt is recommended that you wear respirator when you use the detergent such as IPA.

This method helps to remove dust and harmful gases that are adsorbed on the board surface.It, however, is a complex operation and involves high cost.

Step 4 Reuse boards.

Due to the limited number of spare boards, you can use the cleaned boards to replace the dirtyones.

----End

3.2 Backup and RestorationThis section describes how to back up and restore configuration files.

3.2.1 Backing Up the Configuration Files

3.2.2 Restoring the Configuration Files

3.2.1 Backing Up the Configuration Files

ContextYou can back up the configuration files by using the following ways.

Procedurel Copying the Screen Directly

In the CLI, run the display current-configuration command. Copy all the display to txtdocuments, then back up the configuration files to the hard disk of the maintenance terminal.

l Backing Up the Configuration Files Through TFTP1. Copy the configuration files in the CF card directly.

This action is to back up the current configuration files that are stored in the CF cardof the router.

After startup of the device, use the following commands to back up the configurationfiles in the CF card of the router.



3-7

<Quidway> save config.cfgWarning: This operation will save the configuration to cfcard:/config.cfg. Continue? [Y/N]:yNow saving the current configuration to the device...Info:Save the current config to cfcard:/config.cfg successfully!<Quidway> copy config.cfg cfcard:/backup.cfgWarning: File cfcard:/config.cfg will be copied to cfcard:/backup.cfg. Continue? [Y/N]:yInfo: Copying file cfcard:/config.cfg to cfcard:/backup.cfg ...100%

2. Assign an IP address for the router.

The router acts as the TFTP client.

Connect the router to the maintenance terminal. Establish the Telnet environment andassign an IP addresses for the interface. Ensure that the IP address of the routerinterface and the IP address of the TFTP server are in the same network segment.

3. Start up the TFTP server application program.

Start up the TFTP server application in the PC. Set the path, the IP address, and theport number of the TFTP server to download the configuration files.

4. Transfer the configuration files.

On the CLI interface, run the tftp command. For example:<Quidway> tftp 10.110.24.209 put config.cfg Transfer file in binary mode. Now begin to copy file to remote tftp server, please wait for a while TFTP: 1503 bytes sent in 1 seconds. File uploaded successfully!

l Backing Up the Configuration Files Through FTP1. Connect the router to the maintenance terminal, establish the Telnet environment and

assign an IP address for the interface.2. Start up FTP service.

The router acts as the FTP server.

Start up the FTP server on the router. Create an FTP user whose username is routerand password is 123. Authorize the user to visit cfcard:\.<Quidway> system-view[Quidway] ftp server enable[Quidway] aaa[Quidway-aaa] local-user router password simple 123[Quidway-aaa] local-user router ftp-directory cfcard:/[Quidway-aaa] local-user router service-type ftp

3. Initiate an FTP connection to the router from the maintenance terminal.

On the PC, establish an FTP connection with the router through the FTP client. Forexample, the IP address of the router is 10.110.24.254.C:\Documents and Setting\Administrator> ftp 10.110.24.254Connected to 10.110.24.254.220 FTP service ready.User (10.110.24.254:(none)): router331 Password required for router.Password:230 User logged in.

4. Set the parameters.

After the FTP user passes authentication, the FTP client prompts "ftp>". Enterbinary and specify the directory for storing the configuration files on the FTP client.


Routine Maintenance


Issue 03 (2009-09-20)

ftp> binary200 Type set to I.ftp> lcd c:\tempLocal directory now C:\temp.

5. Transfer the configuration files.

Run the get command on the PC to download the configuration files to the localspecified directory and save them as backup.cfg.

----End

3.2.2 Restoring the Configuration Files

ContextYou can restore the configuration files through the following ways.

NOTE

After restoring the configuration files, reset the router to make the configuration files take effect.

Procedurel Recovering the Configuration Files Saved in the CF Card

This action is to restore the configuration files saved in the CF card of the router as theconfiguration files of the current system.

Run the following commands when the router works normally.

<Quidway> copy backup.cfg cfcard:/vrpcfg.zipWarning: File cfcard:/backup.cfg will be copied to cfcard:/vrpcfg.zip. Continue? [Y/N]:yWarning: File cfcard:/vrpcfg.zip already exists. This operation will overwrite it. Continue? [Y/N]:yInfo: This operation will take several minutes. Please wait for a moment...succeeded.Info: Copying file cfcard:/backup.cfg to cfcard:/vrpcfg.zip ...100%

l Recovering the Configuration Files Saved in the PC Through TFTP

The router works as the TFTP client. The restoration procedure is similar to that of backingup the configuration files through TFTP. Run the tftp get command to download theconfiguration files saved in the PC to the CF card of the router.

l Recovering the Configuration Files Saved in the PC Through FTP

The router acts as the FTP server. The restoration procedure is similar to that of backingup the configuration files through FTP. Run the put command to upload theconfiguration files saved in the PC to the CF card of the router.

6.1 Risky Hardware OperationsThe following hardware operations may affect the service running and hardware safety or harmthe human body; therefore, perform the following operations with caution.

Table 6-1 Risky hardware operations

Item Sub-item Consequences of Mal-operations

Operationson boards

Hot swapping the in-service active main boardis prohibited.

l When the standby main board runs normally,data synchronization between the activeboard and the standby one requires a certainperiod. When the active main board isplugged out, the system performs automaticswitchover. The latest data on the active mainboard, however, cannot be backed up entirelyto the standby main board. This results inwrong statistics and data loss.

l When the standby main board fails, removingthe in-service active main board results ininterruption of part of or even all services.

Pressing the Reset buttonon the main board at will isprohibited.

l Pressing the Reset button on the panel forcesthe board to reset its hardware. This operationcan be carried out only by the qualifiedpersonnel when fatal faults occur in thesystem.

l If the Reset button on the panel is pressed bymistake, the main board will be reset. Itsresults are the same as those of removing thein-service active main board.

Inserting or removingboards without wearing anantistatic wrist strap isprohibited.

l Electrostatic discharge on human bodydamages electrical components on the board.

l If the maintenance personnel insert or removeboards without wearing an antistatic wriststrap, the board may be damaged or may notrun properly.

Operationson boards

Debugging the serial portof the board through theserial cable is prohibited.

Only Huawei engineers can use the debuggingserial port. Otherwise, abnormality of boardprogram or board resetting may be caused.

Operationsfor cable

Installing or removingnetwork cables inside thecabinet at will isprohibited.

l The network cables inside the cabinet are usedfor communication between the host and themaintenance terminal.

l Installing and removing the cables inside thecabinet at will may cause the maintenanceterminal to fail to log in to the switch.
