If a Boot ROM upgrade is required, you can perform this task to shorten the subsequent upgrade
time. This task helps avoid upgrade problems caused by unexpected electricity failure.
If you skip this task, the device upgrades the Boot ROM automatically when it upgrades the startup
software images.
The Boot ROM image preloaded into the Boot ROM does not affect the device running status.
4. Specify the image file as the startup software image file.
5. Reboot the device.
6. Verify the upgrade.
Preparing for the upgrade
1. Use the display version command to verify the current Boot ROM image version and startup
software version.
2. Use the release notes for the upgrade software version to evaluate the upgrade impact on your
network and verify the following items:
{ Software and hardware compatibility.
{ Version and size of the upgrade software.
{ Compatibility of the upgrade software with the current Boot ROM image and startup software
image.
3. Use the release notes to verify whether the software images require a license. If licenses are
required, register and activate licenses for each license-based software image. For more
information about licensing, see "Managing licenses."
4. Use the dir command to verify that sufficient storage space is available for the upgrade images. If
the storage space is not sufficient, delete unused files by using the delete command. For more
information, see "Managing the file system."
NOTE:
On the MSR4000 router, make sure both MPUs have sufficient storage space for the upgrade
images.
5. Configure FTP and TFTP settings.
6. Use FTP or TFTP to download the upgrade file to the root directory of a storage medium.
NOTE:
On the MSR4000 router, you can save the up
g
rade file to the root directory of the CF card on
any MPU. If the file is not on the MPU you are up
g
radin
g
, the router automatically copies the ima

from the specified file path to the MPU.
For more information about FTP and TFTP configuration and operations, see "Configuring FTP" or
"Configuring TFTP."
