Replacing Cards
Step 4 Use the loadrev command to prepare the standalone service module 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
Filenames" in
The mpsm parameter is required to enable loading of MPSM software for a slot that is configured for
another 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 5 Use the runrev command to configure the standalone service module 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 slot number for the legacy service module, 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 another type of card. The following example shows how this command is used:
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 standalone service module will reset and the card state, which
you can view with the dspcds command, will change to mismatch.
Step 6 Remove the standalone service module from the slot you have prepared for the MPSM.
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.
