3.1.5 Removing Dust from Fan Modules

Context

The fan modules are part of a device. The fan modules of the NE80E and NE40E-8 are locatedat the top of the chassis; those of the NE40E-4 are located on the right of the chassis. The fanmodules help in heat dissipation and ventilation of the entire system.

During the running of a device, the fans and the Fan Control Board (FCB) of the fan modulesabsorb dust. When a lot of dust is accumulated, the stable running of the fan modules is affectedand the dust becomes the pollution source of the chassis, which poses a latent hazard to stablesystem running.

To ensure the long-term stability of a device, it is recommended to remove dust from each fanmodule once a year as follows:

Procedure

Step 1 Remove dust from a spare fan module.

Remove dust from the fans and the FCB of a spare fan module with the clean gauze, antistaticsoft brush, or the vacuum cleaner.

Step 2 Replace the fan module to be cleaned with the spare one.

For detailed operations, refer to the"Quidway NetEngine80E/40E Universal Service RouterParts Replacement".

CAUTIONMaintainers must spend no more than five minutes to replace a fan frame. Otherwise, the securityand stability of the device is severely affected.



3-11

Step 3 Remove dust from the replaced fan module.

Remove dust from the fans and the FCB of the replaced fan module with the clean gauze,antistatic soft brush, or the vacuum cleaner. The fan module cleaned is used as a spare one.

3.1.6 Removing Dust from Boards

Context

DANGERl Use antistatic measures in the whole process. For example, you have to operate at an antistatic

table and wear antistatic clothes and wrist straps.l Choose the qualified detergent; otherwise, the board will be damaged.

CAUTIONRemoving boards may significantly affect the running of services. Therefore, you should removedust from boards during a period when the service traffic is light, for example, between 2:00and 4:00 a.m.

During the running of a device, dust accumulates on the boards due to cross ventilation in theprocess of heat dissipation. The lower the air cleanliness and relative humidity are, the higherthe accumulation of dust is. The worse the air cleanness is and the lower the relative humidityis, the more dust is absorbed. When a certain amount of dust is accumulated, it affects the heatdissipation and the electric insulation of boards. It thus threatens the stable running of the device.

You are recommended to clean dust for all boards once in every two years.

The steps are described as follows.

Procedure

Step 1 Prepare spare boards.

To clean dust for all boards, you need to prepare a spare board for each board.

Step 2 Replace boards.

Replace a board with the spare board first. You cannot remove dust from the board until thespare one is in position and runs normally.

Step 3 Remove dust.

You can carry out dust cleaning in many ways. Two ways for dust cleaning are as follows.

l With vacuum cleaner


Routine Maintenance


Issue 03 (2010-08-30)

Brush dust from board surface with a clean and dry antistatic soft brush and align the dustintake of a vacuum cleaner with the brush. In this case, dust is absorbed immediately whenit is brushed off.

This method features simple operation and low cost. It is hard to remove the dust that isabsorbed on board surface such as harmful gas.

l With detergent

Use dedicated anhydrous, erosion-free, non-conductive and highly volatile detergent suchas Isopropyl Alcohol (IPA) to remove dust from boards.

This method helps to remove dust completely, even those harmful gases that are adsorbedon board surface. It, however, features complicated operation and high cost.

Step 4 Reuse boards.

Due to the amount limit of spare boards, it is not possible to replace all the boards with spareboards simultaneously.

You can repeatedly use the cleaned board to replace other boards the types of which are the samefor secure maintenance.

----End

3.1.7 Removing Dust from Optical Interfaces and Connectors

Context

After a period of the running of a device, you need to remove dust from optical interfaces onboards and connectors on tail fibers.

Protection Against Laser

DANGERThe optical interface produces invisible infrared laser, which can cause permanent injury to eyes.

WARNINGDo not use unqualified cleaning tools or materials. This may damage the optical connectors andinterfaces.

When performing an operation on optical connectors, you are recommended to wear infraredfilter glasses to prevent your eyes from being hurt by invisible laser. If you do not wear suchglasses, do not look directly into the optical connector of an optical interface.



3-13

Capping Optical Interfaces and Connectors

Cover the free optical interfaces on boards and connectors on tail fibers with protective caps.When you pull the tail fiber out of an optical interface, place a cap on the interface and theconnector on the tail fiber.

Capping them helps to:

l Prevent laser from hurting the eyes

l Prevent dust from accumulating on optical interfaces and connectors

Do as follows to clean optical interfaces and connectors:

Procedure

Step 1 Pull out an interface board.

Before pulling out an interface board, remove the fibers that are inserted to the boards.

It is recommended to perform this step under the guidance of Huawei engineers to avoid damageto the boards.

Step 2 Clean them with dedicated tools and materials.

Use dedicated tools and materials to clean optical interfaces and connectors. You can purchasethe tools and materials from fiber suppliers.

For large-power optical interfaces and connectors, you must use dedicated tools and materialsto clean them.

For small-power optical interfaces and connectors, you can use clean, dry antistatic brushes ifdedicated tools and materials are unavailable.

----End

Loopback Test on Optical Interfaces

When you conduct a loopback test on the optical interface with the tail fiber, add an attenuatorto:

l Prevent the optical module from overload due to received high optical power

l Prevent the optical module from being damaged due to high optical power that is received

3.2 Backup and RestorationHow to back up and restore data.

For the router, backup and restoration involves:

3.2.1 Backing Up the Configuration File

3.2.2 Restoring the Configuration Files

3.2.1 Backing Up the Configuration File


Routine Maintenance


Issue 03 (2010-08-30)

ContextA configuration file can be backed up in the following manners:

Procedurel Directly Copying the File

1. Run the display current-configuration command on the command line interface andcopy all command outputs into a .txt file. In this manner, the configuration file isbacked up into the hard disk of the maintenance terminal.

l Backing Up the File Through TFTP1. Directly copy the configuration file to the CFcard.

You can take the step to copy the current configuration file immediately to the CFcardof a router. Run the following commands to copy the configuration file to the CFcardof a router before starting the router:

<Quidway> copy vrpcfg.zip cfcard:/backup.zipCopy cfcard:/vrpcfg.zip to cfcard:/backup.zip?[Y/N]:y100% completeInfo:Copied file cfcard:/vrpcfg.zip to cfcard:/backup.zip...Done

2. Assign an IP address to the router.

The router functions as a TFTP client.

Connect the router and maintenance terminal to set up a Telnet environment. Assignan IP address to the interface on the router. Ensure that this IP address and the IPaddress of the TFTP server are in the same network segment.

3. Run the TFTP server application program.

3.3 Grounding System MaintenanceHow to maintain the grounding system.

3.3.1 Checking the Grounding System

3.3.2 Measuring the Grounding Resistance

3.3.1 Checking the Grounding System

To maintain the grounding system, check the following:

l The electrical contact between the metallic parts and the cabinet body. The metallic partsand the cabinet body must be well contacted. The contact points such as screw holes, guidelanes, and lifting ears must not be painted. Otherwise, bad electrical contact may occur.

l The grounding terminals at the front and back doors and the side doors. These terminalsmust be well connected with the grounding wires.

l The grounding buses of combined neighboring cabinets. If cabinets are combined, theneighboring cabinets must be connected by a grounding bus.

l The yellow and green protecting grounding cables. One end of a grounding cable shouldconnect the PGND grounding bus of the power distribution cabinet in the equipment room,and the other end connects the grounding terminal of the cabinet. The screws that fix thegrounding cable should not be loose.

3.3.2 Measuring the Grounding ResistanceNOTE

The grounding resistance of a comprehensive communication building should be no more than 1 Ω; thatof a common communication station, no more than 5 Ω; that of the place with high earth resistibility, nomore than 10 Ω.

To measure the grounding resistance, use an earth resistance tester. Figure 3-15 shows the arrangementof the probes of an earth resistance tester.



3-17

Figure 3-15 Arrangement of probes of an earth resistance tester

NOTE

l Position the current probe and the voltage probe in a manner that is perpendicular to the wires of agrounding net or underground metallic pipes.

l Do not measure the grounding resistance right after a rain.

l If the distance between the current probe and the rim of a grounding net is d1 and the lengthof the maximum diagonal line of a grounding net is D: d1 is normally four to five times asmuch as D.

l If the distance between the probe and the side of a grounding net is d2, then d2 is 50% to60% of d1.

l In measurement, move the voltage probe along the line connecting the grounding net andthe current probe for three times; each movement is about 5% of d1. If the three resistancevalues are similar, it means that the grounding resistance is normal.

NOTE

If you feel difficult to measure d1, you can take 2D instead of d1, D instead of d2, in a place where theearth resistibility is uniform. In a place where the resistibility is not uniform, you can take 3D instead ofd1, 1.7D instead of d2 as the data.

Hot swapping the mastermain control board isprohibited

l When the standby main control board runsnormally, data backup from the master boardto the standby one requires a certain period. Inthis case, the latest data on the main controlboard cannot be backed up entirely to thestandby board. Therefore, removing the in-service master control board may result inincorrect statistics and data loss.

l When the standby main control board fails torun, removing the in-service master board mayresult in interrupt of partial or even globalservices.

Pressing the Reset buttonon the main control boardat will is prohibited

l If you press the Reset button on the panel, theboard is forced to reset the hardware. Thisoperation can be carried out only by thequalified personnel in case that fatal faultsoccur in the system.

l If the Reset button on the panel is pressed bymistake, the main control board will be reset.Its results are the same as those of removingthe in-service master control board.
