Aftereffects that may be caused by maloperation

Operations on boards

Hot swapping the master main control board is prohibited

  • When the standby main control board runs normally, data backup from the master board to the standby one requires a certain period. In this case, the latest data on the main control board cannot be backed up entirely to the standby board. Therefore, removing the in-service master control board may result in incorrect statistics and data loss.

  • When the standby main control board fails to run, removing the in-service master board may result in interrupt of partial or even global services.

Pressing the Reset button on the main control board at will is prohibited

  • If you press the Reset button on the panel, the board is forced to reset the hardware. This operation can be carried out only by the qualified personnel in case that fatal faults occur in the system.

  • If the Reset button on the panel is pressed by mistake, the main control board will be reset. Its results are the same as those of removing the in-service master control board.

Pressing the OFL button on the board at will is prohibited.

If you press the OFL button, the board is powered off and the service is interrupted.

Inserting and removing boards without wearing ESD wrist strap are prohibited

  • Electrostatic on human body does great harm to electrical parts on the board.

  • If the maintenance personnel insert and remove boards without wearing ESD wrist strap, the board may be damaged or not run stably.

Debugging the Console with the Console cable is prohibited

Only Huawei professional engineers can use the debugging Console; otherwise, abnormality of board running or board resetting may be caused.

Operations for cable

Plugging in and plugging out the network cables inside the cabinet at will are prohibited

  • The network cables inside the cabinet are used for communication between the host and the terminal.

  • Plug-in and plug-out of the cables inside the cabinet at will may make the terminal fail to log on to the router.

Operations for power supply

Operating the power supply in the power distribution frame of the cabinet is prohibited

  • The maintenance personnel can operate the power supply based on the guide only in the case of upgrading, expansion, parts replacement or fatal faults.

  • Operations at will may cause fatal faults such as shut-down of the device and interruption of the services.
