Part Number OL-2523-01 Rev. B0, January 9, 2004
Installation and Upgrade Procedures
Initial Conditions
The following initial conditions are required before the graceful upgrade procedure can be started:
• The MGX 8000 Series shelf must be configured with at least two VISM cards in a redundant
configuration (refer to the add redundancy, addred, command in the MGX 8850, MGX 8250, and
MGX 8230 command references for more information).
• The VISM cards must be running VISM 2.0 and be configured to the desired configuration.
• The software Release 3.0(0) for VISM/VISM-PR must have been already downloaded to the MGX
shelf.
• Ensure that you have the version of VISM software that supports CALEA, if you are using the
CALEA feature.
Upgrade Procedure
Upgrades are available for the following releases:
• From VISM 1.5 to VISM 3.0
• From VISM 2.1 to VISM 3.0
• From VISM 2.2 to VISM 3.0
In the following procedure:
• Two VISM cards are involved, one initially active and one initially standby. In this procedure
description, the initially active VISM is identified as VISM 1 and the initially standby VISM as
VISM 2.
• Old-rev refers to the firmware before the upgrade (2.2).
• New-rev refers to the firmware after the upgrade (3.0).
Complete the following steps to upgrade the VISM cards:
Step 1 Log in to the active PXM card (slot 7 or 8).
Step 2 Save the existing configuration as a contingency plan by entering:
savesmcnf <SM slot#>
This will save the existing configuration in the c:cnf directory. This file can be used during the
downgrade procedure, if necessary.
Step 3 Execute the PXM install command:
install sm <SM slot#> <new-rev>
where:
SM slot# is the slot number of the VISM 2 card and new-rev is the file name of the new firmware (for
example, vism_8t1e1_003.000.000.000.fw).
This command causes the standby VISM 2 to reset and come up in the “hold” state, running the new-rev
firmware. The active VISM 1 is unaffected by this command. At this point, the primary firmware is still
the old-rev and the secondary firmware is new-rev.
