VISM Boot Code Upgrade Procedure with PXM1 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 PXM1 cards in your MGX 8230, MGX 8250, and MGX 8850 chassis:
Note This procedure re-programs the VISM boot code for previous VISMs using the VISM runtime image
version 1.0 to 2.0.
Step 1 Telnet to MGX shelf and cc to the VISM card.
Note VISM must be in the active state in order to update the VISM boot code.
Step 2 Access the server where the VISM boot code resides and TFTP the VISM boot code to the VISM card
with the following procedure:
a. Type tftp <IP address of the MGX shelf>
b. Type bin at the tftp prompt.
Caution Ensure that you perform Step 2b. If you to not perform Step 2b. the boot code will be corrupted and
not recoverable.
c. Type install [bt] [sm <slot>] <version> at the PXM prompt.
Caution Do not touch the VISM card until the status comes back ('Sent xxx bytes in yyy seconds'). Failure to
follow this recommendation will corrupt the boot code and it will not be recoverable.
When the boot code is being written to PROM, you will see comments displayed at the VISM prompt.
This is normal and expected behavior.
Step 3 Use the resetcd command for VISM from the PXM card for the latest boot take effect.
Step 4 Type the version command to verify the correct boot code.
