Update Software
Each module in the Universal Chassis System has two flash memory banks that store software:
• The Active Flash Memory holds the software currently in use
• The Inactive Flash Memory holds the new software from a download or the older version of
software
Software is downloaded to the inactive region to avoid disrupting service. Resetting the module
and swapping banks does not affect module operation and is transparent to user traffic.
Use the Software Upgrade report and menu screen to check the current version of the DMM
firmware and to upgrade software for any module, except the CIM, in the domain or a managed
module partner, if necessary.
To access the Software Upgrade screen, follow these steps:
1. At the Domain Management Module menu, type 4 , Software Upgrade, and press <Enter>.
The Software Upgrade screen appears.
2. Record the Processor Version and the numbers for the Active and Inactive Firmware.
3. Contact your technical support person for assistance to determine if you need to update your
software and to receive the new file.
Caution: To insure compatibility when a system includes two or more of the same module,
you must upgrade all those modules with the same software.
