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 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. Access the Canoga Perkins Web site, click Downloads, scroll to the DMM filename, and
compare the version number listed there with the version numbers you recorded. The DMM
firmware file name is similar to
DMM0106.zip , where "DMM" indicates the module and
"0106" indicates the version.
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.
If the firmware for the DMM or other module is outdated, you need to upgrade it. To start the
software upgrade, follow these steps:
1. Go to the Host Access Table (see page 3-15) and verify that the entry for the host you will
use for the file transfer allows FTP or SFTP access, depending on the method you plan to use.
2. Log in to the FTP or SFTP server from the account that allows access.
Note: You can run only one FTP or SFTP session at a time.
