Rebooting the device

To reboot the device, use one of the following methods:
Reboot the device at the CLI. You can remotely reboot the device in either of the following ways:
•
Reboot the device immediately by using the reboot command.
Schedule a reboot to occur at a specific time or date or after a delay by using the schedule
reboot command.
Power off and power on the device. This method cuts off the power of the device forcibly, which
•
might cause data loss. It is the least-preferrred method.

Restrictions and guidelines

Before you reboot the device, perform the following tasks:
•
Use the save command to save the running configuration. For more information about the save
command, see H3C WX5540H Access Controller Fundamentals Command Reference.
Use the display startup and display boot-loader commands to make sure you have specified
the correct next-startup configuration files and startup software images. If the main startup
software image is corrupt or does not exist, a reboot failure will occur. To avoid a reboot failure,
use the boot-loader file command to specify a new startup software image. For more
information about the display startup and display boot-loader commands, see H3C
WX5540H Access Controller Fundamentals Command Reference.
• The device will not reboot if a file is being accessed.
