Before powering off the USG, ensure that configuration data is saved. Otherwise, the
configuration data may be lost.
If the USG will be administratively shut down for a long time, turn off the power switch.
After powering off the USG, set it aside properly according to storage requirements.
If the USG has hard disks, do not power off the USG by removing the power cable or
switching off the power supply to prevent data loss and hard disk damage. You must run the
disk offline command in the system view first and wait for about 30 seconds. After the system
prompts you with a message indicating that hard disks have stopped, turn off the power
switch of the USG.
