Replacing Cards
Step 7 Insert the MPSM-8-T1E1 card in the slot used in the previous steps.
The MPSM-8-T1E1 will cycle through the Boot, Init, and Standby states, and become Active. If the
software version specified in the loadrev and runrev commands is already stored in the flash memory
on the MPSM, this process is faster than the start up time for the replaced service module. If the software
version isn’t in flash, it must be downloaded from the PXM and the bring up time will be about the same
as for the replaced service module.
Step 8 To finalize the upgrade, enter the commitrev command. The command format is:
M8850_SF.7.PXM.a > commitrev <slotNo> <mpsm-rev>
Use the same slot number and revision number used in the previous steps. For example:
M8850_SF.7.PXM.a > commitrev 13 30.0(0.85)A
Replacing the Secondary Card in a Redundancy Group
When upgrading the secondary 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 there is no redundancy protection for primary cards during the
upgrade.
The following procedure describes how to upgrade the secondary card in a redundant configuration to
MPSM-8-T1E1.
Step 1 If you have not done so already, upgrade the PXM software to a version that supports the MPSM software
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 5.1.00 or the Release
Notes for the Cisco MGX 8880 Media Gateway, Release 5.0.02.
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 Switch” section in Appendix A, “Downloading and Installing Software
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 “Determining the Software
Version Number from Filenames” in Chapter 9, “Switch Operating Procedures.”
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 “Service
Modules that Can Be Upgraded to MPSM-8-T1E1” section.
Step 6 Insert a MPSM-8-T1E1 in the secondary slot.
Step 7 Use the setrev command to initialize the MPSM card as described in the “Initializing Service Modules”
section in Chapter 4, “Preparing Service Modules for Communication.”
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 “Establishing Redundancy Between Two Service Modules”
section in Chapter 4, “Preparing Service Modules for Communication.”
