Replacing 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.
Use the loadrev command to prepare the primary card slot for the MPSM software. The command
Step 3
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 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:
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.
Remove the primary card from the slot you have prepared for the MPSM.
Step 5
Insert the MPSM-8-T1E1 card in the slot used in the previous steps.
Step 6
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.
