Upgrading from the CLI
• Boot ROM image
• Comware images
(excluding patches)
This method is disruptive. You must reboot the
entire device to complete the upgrade.
Upgrading from the Boot
menu
• Boot ROM image
• Comware software
images
Use this method when the device cannot start up
correctly.
IMPORTANT:
The Boot menu method increases the service
downtime, because it requires that you upgrade
the member devices one by one.
This chapter only covers upgrading software from the CLI.
Upgrade procedure summary
To upgrade software from the CLI:
1. Download the upgrade software image file.
2. Register and activate licenses for license-based images. Skip this step if no license is required or
the device already has a valid running license for each license-based image.
3. (Optional.) Preload the Boot ROM image to the Boot ROM.
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.
