Replacing Cards
M8850_SF.7.PXM.a > runrev 13 30.0(0.85)A mpsm
one or more card(s) in the logical slot may be reset.
runrev: Do you want to proceed (Yes/No)? y
After you enter the runrev command, the primary card will reset and the card state, which you can view
with the dspcds command, will change to mismatch. The secondary card will become active and take
over the run-time operations for the primary card.
Step 5 Remove the primary card from the slot you have prepared for the MPSM.
Step 6 Insert the MPSM-8-T1E1 card in the slot used in the previous steps.
The MPSM-8-T1E1 will cycle through the Boot and Init, and enter the Standby state. 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 previous primary card. 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 previous primary card.
Step 7 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
After you enter this command, the switch automatically makes the primary card active and resets the
secondary card.
Replacing Service Modules with a Different Type of Service Module
To replace one type of service module front card with a different type, you must first delete the
configuration for the previously installed service module. The easiest way to do this is by using the
clrsmcnf -all command as described in the “Clearing a Slot Configuration” section of Chapter 9,
“Switch Operating Procedures.”
Replacing SRM Cards with SRME/B
The SRME/B card is designed to replace SRME and SRM-3T3 cards and to work with the back cards
used by SRME and SRM-3T3. When upgrading SRM cards, you must upgrade both the software and the
hardware. After an upgrade, the SRME/B uses the configuration previously assigned to the SRME or
SRM-3T3. The following procedure describes how to replace SRM cards with SRME/B.
Step 1 If you have not done so already, upgrade the PXM software to a version that supports the SRME/B,
which is Release 5 or later. 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 this is a redundant PXM and SRM configuration, replace the standby SRM front card with SRME/B.
Otherwise, replace the standalone SRM front card.
Note If this is a standalone PXM and SRM installation, replacing the standalone SRM interrupts all SRM
services.
