Chapter1 Overview of the VISM and VISM-PR Cards
Installing VISM Hardware and Software
Step 3 Execute the PXM install command for the backup boot image:
install bt sm <SM slot#> <new bb rev>
where:
SM slot# is the slot number of the active card, and new bb rev is the version number of the new backup
boot image.
This command downloads the backup boot image to the flash in the VISM card slot you specified. The
new backup boot image takes effect upon the next card reset.
Step 4 Execute the PXM install command:
install sm <SM slot#> <new-rev>
where:
SM slot# is the slot number of the VISM card that was active before the upgrade process started, and
new-rev is the file name of the new firmware (for example, vism_8t1e1_002.001.000.000.fw).
This command causes the standby VISM card to reset and be placed in the hold state, running the
new-rev firmware. The active VISM card is unaffected by this command. At this point the primary
firmware is still the old-rev and the secondary firmware is new-rev.
Step 5 Execute the PXM newrev command:
newrev sm <SM slot#> <new-rev>
where:
SM slot# is the slot number of the VISM card that was active before the upgrade process started, and
new-rev is the filename of the new firmware.
This command causes the standby VISM card to become the active VISM card running the new-rev
firmware. The previously active VISM card is placed in the hold state, becoming the new standby VISM
card, and is still running the old-rev firmware. The primary and secondary firmware switches with the
new-rev becoming the primary firmware.
Step 6 Execute the PXM commit command:
commit sm <SMslot#> <new-rev>
where:
SM slot# is the slot number of the new standby VISM card and new-rev is the filena me o f th e new
firmware.
This command causes both VISM cards to run the new-re v f irmw are. Af ter a s hort time, the cards s witch
automatically so that the originally active VISM card becomes the active card and the origin ally standb y
VISM card becomes the standby card. The two VISM cards are now back to their original condition
except that both cards are now running the new-rev firmware.
Step 7 Log in to the active VISM card and use the display commands (dspendpts, dspcasvar, etc.) to confirm
that the configuration has been preserved through the upgrade process.
Cisco recommends that you further verify the configuration by making some minor modi fications to the
configuration, checking that the changes have been executed correctly, and then changing the
configuration back again.

VISM-PR card specifications.
