Procedure
Step 1 Wear the ESD wrist strap, and insert the grounding end into the ESD jack on the
device, or wear ESD gloves.
Step 2 Make sure that the spare part is the same as the one to be replaced in terms of
name, model, and parameters. If they do not meet the requirements, contact
Huawei GTAC.
Step 3 Check whether the control board to be replaced is the slave control board. If it is
the master control board, perform a master/slave control board switchover.
Step 4 Check the version information of the software package in use. Check whether the
software package file, configuration file, and patch file in use are the same as the
startup software package file, configuration file, and patch file, respectively.
Step 5 Save the configuration file in use.
Step 6 Record the slot of the control board and fiber or cable connections of interfaces
on the boards. When the part replacement is complete, restore the fiber or cable
connections.
Step 7 Remove cables connected to the board and attach labels onto these cables.
Step 8 Remove the board from the chassis, and insert the new one into the chassis.
