9.1.2. Hot Plugging

The device supports the hot plugging of the system control board in the normal running, and the configuration information of the original card is saved in the system in the plugging process.

„If the device is just configured with a system control board, the system will not run when you unplug the system control board.

„If the device is configured with two system control boards, the system will run normally when you unplug the standby system control board. If you unplug the master system control board,

the master/standby switchover will occur to the device.

After unplugging a card from a slot, you cannot plug a new card immediately, and you should do it in a minute.

Note

During the system startup process, the hot plugging is not supported.

9.1.3. Master/Standby Switchover

The master/standby switchover refers to that the master/standby relationship switchover happens when the system control board is operated manually or some faults occur to it in the redundancy mode.

The master/standby switchover is a self-protection function of the system. When some faults occur to the master system control board, the master/standby is implemented automatically. In this way, the service is transferred to the standby system control board, and the system can continue to run.
