Chapter 10 Switch Maintenance Procedures
The following procedure describes how to upgrade the secondary card in a redundant configuration to
MPSM-8-T1E1.
If you have not done so already, upgrade the PXM software to a version that supports the MPSM software
Step 1
you will be using. For more information, refer to the Release Notes for Cisco MGX 8850
(PXM1E/PXM45), Cisco MGX 8950, and Cisco MGX 8830 Switches, Release 5.0.00 or the Release
Notes for the Cisco MGX 8880 Media Gateway, Release 5.0.00.
Step 2 If you have not done so already, copy the MPSM runtime software to the switch as described in the
"Copying Software Files to the
Upgrades."
MPSM runtime files are named using the following format: mpsm_t1e1_030.000.000.000.fw. The
numerals in the file name indicate the software version as described in
Version Number from
Step 3 Establish a configuration session using a user name with SERVICE_GP privileges or higher.
Step 4 Remove the redundancy configuration for each primary card in the redundant group using the delred
command. The command format is:
PXM1E_SJ.8.PXM.a > delred <primarSlotNo>
Step 5 Remove the secondary card you are replacing. This should be one of the card types listed in the
Modules that Can Be Upgraded to
Step 6 Insert a MPSM-8T1E1 in the secondary slot.
Step 7 Use the setrev command to initialize the MPSM card as described in the
section in
Step 8 Use the addred command to establish redundancy between the primary cards reconfigured in Step 4 and
the new MPSM card as described in the
section in
After redundancy has been added to all primary service modules, the redundant configuration is restored
and the MPSM-8-T1E1 now serves at the secondary card for all protected cards. To upgrade primary
cards to MPSM-8-T1E1, use the procedure in the next section.
When the primary card is not an MPSM-8-T1E1 and the primary card is running a software version
Note
released prior to Release 5.0, provisioning is blocked whenever the secondary MPSM-8-T1E1 is active.
To prevent blocking provisioning, upgrade all primary cards to the latest release after upgrading the
secondary card to MPSM-8-T1E1.
Replacing a Primary Card in a Redundancy Group
When upgrading the primary card in a redundant service module configuration to MPSM-8-T1E1, you
must upgrade both the software and the hardware. The software configuration and feature licenses
remain intact during the upgrade, but active connections are briefly interrupted when switching between
primary and secondary cards.
