Rebooting the device
When a fault occurs to a running device, reboot the device with any of the following methods to remove
the fault:
• Power on the device after powering it off, which is also called hard reboot or cold start. This method
impacts the device a lot. Powering off a running device will cause data loss and hardware damages.
It is not recommended.
• Trigger the immediate reboot at the CLI.
• Enable the scheduled reboot function at the CLI. Set a time at which the device can automatically
reboot, or set a delay so that the device can automatically reboot within the delay.
The last two methods are command line operations. Reboot through command lines is also called hot
start, which is mainly used to reboot a device in remote maintenance without performing hardware
reboot of the device.
