Installation and Upgrade Procedures
VISM Boot Code Upgrade Procedure with PXM1E and PXM45 Cards
There is a new backup boot code change from VISM Release 2.2(0) to software Release 3.1(1) for
VISM/VISM-PR. Complete the following steps to upgrade the new backup boot code when you are
using PXM1E or PXM45 cards in your MGX 8000 Series chassis:
Step 1 Complete the steps in the VISM Firmware and Boot Code Download Procedure for PXM1E and PXM45,
page 9.
Step 2 Log on to the PXM1E or PXM45 card.
Step 3 Use the burnboot sm-primary-slot-num new-rev command, where sm-primary-slot-num is the slot
number of the VISM/VISM-PR card you want to upgrade and new-rev is the firmware version number
of the new VISM software, to upgrade the VISM/VISM-PR boot code.
The VISM/VISM-PR card automatically resets and becomes active with the latest boot code image. You
have completed the boot code upgrade procedure.
VISM Downgrade Procedure
Use this procedure to downgrade VISM software from software Release 3.1(1) for VISM to the earlier
VISM Releases 3.1, 3.0, 2.2, 2.1, and 2.0. By following the downgrade procedure described here, the
configurations will be retained after downgrade.
Note It is important to note that the configurations that existed with old-rev firmware should have
been saved earlier. You cannot downgrade from VISM-PR to VISM.
Complete the following steps to downgrade the VISM software from software Release 3.1(1) for
VISM/VISM-PR to Release 3.1, 3.0, 2.2, 2.1, or 2.0:

The VISM card will be reset on executing this command. Wait for the card to come active.
Step 4 Execute the PXM restoresmcnf command:

where:
The filename is the name of the old configuration file that was saved while the old-rev firmware was
running. The file can be found in the C:CNF directory on the MGX shelf.
The SM slot# is the slot number of the VISM card to be downgraded.
