Installation and Upgrade Procedures • Two VISM cards are involved in a redundancy group, initially with the primary card in the active state and the secondary card in the standby state. • Old-rev refers to the firmware before the upgrade (2.2). • New-rev refers to the firmware after the upgrade (3.1). Step 1 Log in to the active PXM1 card (slot 7 or 8).

Installation and Upgrade Procedures Note If the VISM card is not part of a redundancy group, Step 1 to Step 3 are sufficient. VISM to VISM-PR Hardware Upgrade Complete the following steps to upgrade your system from VISM cards to VISM-PR cards. Caution You must install the redundant (standby) VISM-PR card first; failure to follow this recommendation results in traffic loss.
PAGE 12
Installation and Upgrade Procedures Caution Installing VISM software updates from VISM Release 2.2 with CALEA to VISM Release 3.0 without CALEA is not graceful. Caution Temporary traffic loss occurs during Step 4 and Step 5 of the VISM graceful upgrade procedure of the Upgrade Procedure for software Release 3.1(1) for VISM/VISM-PR.

Caveats The VISM card will be reset again. When the card comes active, it will have the old-rev firmware running and will have the old configuration. Step 5 Reconfigure redundancy group, if required. Caveats This section describes resolved and open software caveats for this release of VISM. Caveats describe unexpected behavior or defects in VISM software. Resolved Caveats Table 7 describes the caveats issued against VISM software that have been resolved in software Release 3.1(1) for VISM/VISM-PR.
