About This Document

About This Document Purpose This document provides guidelines on replacing parts, for ATN device. The usage precautions are as follows: l

A device can store keys in plaintext, reversible algorithm encryption, or irreversible algorithm encryption mode. The plaintext mode has the low security level, and the irreversible algorithm encryption mode has the highest security level. Use different storage modes for different scenarios. Exercise caution when using an insecure storage mode. The system automatically selects the irreversible algorithm encryption mode to store local user keys. Generally, the reversible algorithm encryption mode is used to store protocol keys to meet interworking requirements.

l

If the plaintext mode is used, a password is stored in plaintext in the configuration file. This results in high security risks. The plaintext mode applies only to scenarios with special requirements, such as compatibility and interworking requirements.

l

Using a password or a key without a change leaves the password prone to being stolen or cracked, which is more likely in a longer duration. Changing the password on a regular basis may avoid such incidences, incidences, and therefore therefore is recommended.

Replacing the FAN Board

Impact on the System If the FAN board has to be replaced, replace it quickly. If the device is operating without a fan, high temperature may cause a master/slave control board switchover, a system reset, or even a board burn damage. Under the room temperature (25ºC), replace the FAN board within three minutes.

Precautions

CAUTION When removing the FAN board, do not touch the rotating fan leaves.

Replacing CF Cards

Impact on the System To replace the CF card of a control board, the control board must be removed from the chassis first. If the control board works in 1+1 protection mode, replacing the CF card will not affect services; if the control board does not support 1+1 protection mode, services will be interrupted.

Precautions


NOTICE l

When removing the control board, make sure that the interface is not connected to any fiber jumpers or cables.

Step 3 Record the slot of the board where the C F card is installed. Step 4 (Optional) If the control board works in 1+1 protection mode and the control board whose CF card needs to be replaced is the master control board, run the slave switchover command first to perform a master/slave control board switchover.

Step 5 For detailed precautions and steps for replacing the control board, see Replacing the Control Board of the ATN 910, Replacing the Control Board of the ATN 950B with the 1+1 Protection Mode, or Replacing the Control Board of the ATN 950B without the 1+1 Protection Mode.

Step 6 Slowly remove the CF card, and put it in an ESD bag.

Step 7 Insert the new CF card in the designated slot on the control board and push t he CF card with a finger.

NOTICE l

Ensure that the CF card is correctly inserted.

l

Push the CF card slowly and steadily into the slot. Unsteady operation will cause misalignment between the CF card and pins in the slot, which will in turn cause pin deviation or damages to the CF card.

Step 8 For detailed precautions and steps for installing the control board on the chassis, see Replacing the Control Board of the ATN 910 , Replacing the Control Board of the ATN 950B with the 1+1 Protection Mode, or Replacing the Control Board of the ATN 950B without the 1 +1 Protection Mode.

Step 9 Log in to the device and run the dir ? command to see whether the new CF card information is displayed. If the following information is displayed, the CF card is running. ATN 910 SlotID : 6 /all STRING cfcard:

11 Replacing the Optical Module

Replacing the Optical Module

Impact on the System If optical modules are not in service protection, replacement of an optical module will cause service interruption.

Precautions


NOTICE l

An optical module is an electrostatic sensitive device. Therefore, take ESD measures during the whole process of replacing an optical module to prevent the optical module from being damaged.

l

Only an external optical module can be replaced. An external optical module is pluggable.

l


l

Be careful when you remove or insert an optical cable in case the connector of an optical cable is damaged.

NOTE

You can remove fibers by hands. If dense fibers are inst alled, you can use a fiber extractor t o remove fibers. The following figure shows the appearance of a fiber extractor.

1.

Clamp the top and bottom sides of an LC/PC connector using hands or a fiber extractor and press the spring.

2.

Remove the fiber connector.

3.

Cover the fiber connector with a dust cap.

Step 5 Pull out the optical module to be replaced.

1.

Remove the optical cables from the connector and cover the optical cable connector with a dust cap. NOTE

If optical interfaces such as CXPI/CXPL/EG4F/EF8F/EM4F/EM8F are concave in the board panel and difficult to remove by hands, use a fiber extractor to unfold the handle of the optical module and pull it out.

2.

Turn the pulled handle of the optical module downward, as shown in the figure.

3.

Hold the handle to pull out the optical module carefully from the optical interface, as shown in the figure.

4.

Place the removed optical module in the ESD bag.

Step 6 Insert the new optical module into the optical interface.

NOTICE An optical module must not be inserted inversely. If you cannot completely insert an optical module into the interface, do not push it. Instead, you should reverse it and insert it into the interface again.

1.

Take out the new optical module from the ESD bag and check whether there is any damage or component missing. Check whether the new optical module is of the same type as the optical module to be replaced.

2.

Insert the new optical module into the optical interface, as shown in the figure. When the click of the reed in the optical module is heard, the optical module is correctly inserted.

3.

Remove the dust cap from the connector and insert the optical cables in the original sequence. NOTE

Check whether the LINK indicator on the optical interface works normally. If the indicator is green, the links connected to the interface are Up.

Step 7 Log in to the device and run the display interface interface-type interface-number or display controller cpos cpos-number command to view the type and running status of the new optical module. Check whether the type of the new optical module is the same as that of the original optical module, as the following output in bold displays: GigabitEthernet0/2/1 current state : UP Line protocol current state : UP Link quality grade : GOOD Description:HUAWEI, GigabitEthernet0/2/1 Interface Route Port,The Maximum Transmit Unit is 1500 Internet protocol processing : disabled IP Sending Frames' Format is PKTFMT_ETHNT_2, Hardware address is 3e74-2e7c-cf01 The Vendor PN is FTM-9612C-SL10G The Vendor Name is SOURCEPHOTONICS Port BW: 1G, Transceiver max BW: 1G, Transceiver Mode: SingleMode WaveLength: 1310nm, Transmission Distance: 10km, Transceiver Type: BiDi Rx Power: -2.62dBm, Warning range: [-20.00dBm, -3.00dBm] Tx Power: -5.65dBm, Warning range: [-9.00dBm, -3.00dBm] Loopback:none, full-duplex mode, negotiation: disable, Pause Flowcontrol:Receive
