Replacing Cards
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.
Note When the primary card is not an MPSM-8-T1E1 and the primary card is running a software version
released prior to Release 5, 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.
When upgrading redundant service module configurations, keep the following in mind:
• The secondary card must be an MPSM-8-T1E1.
• If the secondary card is not an MPSM-8-T1E1, the secondary card must be upgraded before
upgrading a primary card.
The following procedure describes how to upgrade a primary card in a redundant configuration to
MPSM-8-T1E1.
Step 1 If you have not done so already, upgrade the secondary card to MPSM-8-T1E1 as described in the
previous section.
Step 2 Establish a configuration session using a user name with SERVICE_GP privileges or higher.
Step 3 Use the loadrev command to prepare the primary card slot for the MPSM software. The command
format is:
M8850_SF.7.PXM.a > loadrev <slotNo> <mpsm-rev> mpsm
Replace the slotNo variable with the slot number for the legacy service module, and replace the
mpsm-rev variable with the version number of the MPSM software. For information on determining the
software version number using the filename, see “Determining the Software Version Number from
Filenames” in Chapter 9, “Switch Operating Procedures.”
The mpsm parameter is required to enable loading of MPSM software for a slot that is configured for a
different type of card. The following example shows how this command is used:
M8850_SF.7.PXM.a > loadrev 13 30.0(0.85)A mpsm
one or more card(s) in the logical slot may be reset.
loadrev: Do you want to proceed (Yes/No)? y
Step 4 Use the runrev command to configure the primary card slot to run the MPSM software. The command
format is:
M8850_SF.7.PXM.a > runrev <slotNo> <mpsm-rev> mpsm
Replace the slotNo variable with the primary card slot number, and replace the mpsm-rev variable with
the version number of the MPSM software. The version number is the same number used with the
loadrev command.
Again, the mpsm parameter is required to enable the operation of MPSM software for a slot that is
configured for a different type of card. The following example shows how this command is used:
