Rebooting a Device
When a fault occurs to a running device, you can remove the fault by rebooting the device, depending
on the actual situation.
You can reboot a device following any of the three methods:
z
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.
z
Trigger the immediate reboot through command lines.
z
Enable the scheduled reboot function through command lines. You can 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.
