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,

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.
