Upgrading Boot ROM

To do...
Enable the scheduled reboot function
and specify a specific reboot time and
date
Enable the scheduled reboot function
and specify a reboot waiting time
CAUTION:
The precision of the rebooting timer is 1 minute. One minute before the
■
rebooting time, the device will prompt "REBOOT IN ONE MINUTE" and will
reboot in one minute.
The execution of the reboot, schedule reboot at, and schedule reboot
■
delay commands can reboot a device. As a result, the ongoing services will be
interrupted. Be careful to use these commands.
If a primary boot file fails or does not exist, the device cannot be rebooted with
■
this command. In this case, you can re-specify a primary boot file to reboot the
device, or you can power off the device then power it on and the system
automatically uses the secondary boot file to restart the device.
If you are performing file operations when the device is to be rebooted, the
■
system does not execute the command for the sake of security.
A Boot ROM file is an application file used to boot the device. When multiple Boot
ROM files are available on the storage device, you can specify a file for the next
device boot by executing the following command.
Follow these steps to specify a file for the next device boot:
To do...
Specify a Boot ROM file on a
card or subcard
CAUTION: The file for the next device boot must be saved under the root
directory of the device (for a device supporting storage device partition, the file
must be saved on the first partition). You can copy or move a file to change the
path of it to the root directory.
During the operation of the device, you can use Boot ROM in the storage device to
upgrade those that are running on the device.
Since the Boot ROM programs of switching and routing processing units (Fabrics)
and line processing units (I/O Modules) vary with devices, users are easily confused
to make serious mistakes when upgrading Boot ROM. After the validity check
function is enabled, the device will strictly check the Boot ROM upgrade files for
correctness and version configuration information to ensure a successful upgrade.
You are recommended to enable the validity check function before upgrading
Boot ROM.
Follow these steps to upgrade Boot ROM:
