Upgrading Card Software

The upgrade process for redundant cards is graceful and does not interrupt service. When you invoke the

process, the system upgrades and restarts only the standby card. You then have the option to commit or

cancel the upgrade. When you commit the software, the system switches to the standby card and then

upgrades the other card.

Warning

Upgrading nonredundant cards interrupts service. Perform nonredundant upgrades

during light traffic periods or during a prearranged maintenance window.

Although you can download software in bulk to multiple nodes, you have to upgrade the software image

manually, one card type at a time. You perform this task from the Cisco WebViewer tool.

To upgrade the software image:

Step 1 Initiate a Cisco WebViewer session with the Cisco MGX 8260 Media Gateway. For more information,

see the “Cisco WebViewer Sessions” section on page 3-4.

Step 2 Log in as the SuperUser or a user with level 1 privileges

Step 3 Click Card>Up/Down Grade. The Upgradeable or Downgradeable Logical Card display opens.

Step 4 Click the + icon for the card you want to upgrade. The Upgrade Software Image and DBM form opens.

Step 5 Specify the name of the upgrade file.

Step 6 Click Up-Grade.

Step 7 For redundant cards, click Up-Grade Commit. The system switches to the standby card and upgrades

the other one. If you don’t want to use the new software, click Up-Grade Cancel.

Note You cannot cancel an upgrade for nonredundant cards.

Step 8 For redundant BSC or NSC upgrades, force a switchback. This is important because the standby card

cannot protect the active card. To force a switchback, click Card>All-Cards; then click the S icon of

the desired card.

Step 9 Repeat this procedure for each card type and each Cisco MGX 8260 Media Gateway.

Parameter Description

version information (R01.02.03) must be 9 characters in length. This name is the

same as the downloaded file name except for the extension.
