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
