Replacing Service Modules With A Different Type Of Service Module; Replacing Srm Cards With Srme/B - Cisco MGX 8850 (PXM1E/PXM45) Configuration Manual

Chapter 10 Switch Maintenance Procedures
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
"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.
If you have not done so already, upgrade the PXM software to a version that supports the SRME/B,
Step 1
which is Release 5.0 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 5.0.00 or the Release
Notes for the Cisco MGX 8880 Media Gateway, Release 5.0.00.
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.
If this is a standalone PXM and SRM installation, replacing the standalone SRM interrupts all SRM
Note
services.
The SRME/B line configuration parameters (which are used only for bulk distribution) are similar to that
Note
of the SRM-3T3, but there are some differences. Replacing a SRM-3T3 with an SRME/B sets all
parameters to the defaults assigned to the SRME/B.
If this is a redundant configuration, the SRME/B will start up in standby state. If this is a standalone
configuration, the SRM should come up in the active state, and the standalone replacement is complete.
Step 3 If this is a redundant configuration, use the switchcc command to switch control from the active PXM
and SRM cards to the standby PXM and SRM cards. The new SRME/B becomes the active card and the
other SRM can be replaced.
Step 4 If this is a redundant configuration, replace the current standby SRM front card with an SRME/B.
