Standby OMU Replacement Guide

 

Scenario: Old Old and  and New New  OMUs OMUs  Running Running the  the Same Operating System This section describes how to replace the standby OMU on BSC6900 configured with two OMUs when the OMU to be replaced and the new OMU have the same operating system.

Prerequisites  

 A new OMU board is ready, ready, and it is of the the same type as the the board to be replaced. NOTE: The OMUc board only runs the Dopra Linux OS.

Context CAUTION:  

To protect the OMU board from the Electrostatic Discharge (ESD), wear an ESD wrist strap and insert its connector into the ESD socket on the cabinet before replacing the board. For detailed operations, see Wearing an ESD Wrist Strap. Strap . If an ESD wrist strap or ground point is unavailable, wear a pair of ESD gloves instead.

Procedure

The OMU application installation package must be uploaded to the \mbsc\upg the \mbsc\upgrade rade directory  directory of the OMU. The OMU application installation package must be named after the version number. That is, after the OMU application installation package is uploaded to the OMU, the directory of the installation package on OMU is "\mbsc\upgrade\V900R014C00." If patches also need to be installed, you must check whether the original patch files exist in the patch folder patch  folder in the OMU application installation package before installing the OMU application. If yes, you must delete the original patch files in the patch patch folder  folder in the OMU application installation package and copy the patch installation package (for example, the V900R01XC0XSPCXXX  folder) saved on the local computer. NOTE: If you need to delete the patch files V900R01XC0XSPCXXX  in the patch  directory, navigate to patch directory, the \mbsc\upg the  \mbsc\upgrade\V900R015C00\ rade\V900R015C00\patch patch directory  directory and then run rm -r  \V900R01XC0XSPCXXX  \V900R01XC0XS PCXXX..

If whether there is any damage, fill in physical BSC6900 Site Maintenance Record Form and Form and pack the replaced board. When packing a board, pay attention to the following points:  

Wear an ESD wrist strap or a pair of ESD gloves.

 

Ensure that each ESD bag or case holds only one board.

When packing multiple boards, isolate them with ESD materials.

Contact the local Huawei office to dispose of the replaced board. NOTE: You You may obtain the name and the PCB version from the panel or bottom of the faulty board.

Setting the Link Mode of the External OMU Ethernet Adapter(For Dopra Linux) This section describes how to set the link mode of the external OMU Ethernet adapters so that it is the same as that of the LAN switch.

Prerequisites The link mode, duplex mode, and rate of the LAN switch have been acquired.

Context There are two link modes of the LAN switch: force mode and auto-negotiation mode. The link mode of the OMU external Ethernet adapter must be consistent with that of the LAN switch. If the link mode of the external Ethernet adapters of the OMU is inconsistent with that of the LAN switch, the network may be interrupted. If the link mode of the LAN switch is specified, the link mode of the external Ethernet adapter of the OMU should also be specified. If active and standby OMUs are a re configured, perform the following steps on both the active and standby OMUs: NOTE:  

 

The following procedure assumes that the link mode of the external Ethernet adapter is force mode and the adapter works at 100 Mbit/s in full duplex mode.
