Upgrading Standalone Configurations
When upgrading a standalone service module 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
all active connections are terminated.
Tip
To avoid service interruption for standalone service modules, configure card redundancy and use the
procedure in the “
Replacing a Primary Card in a Redundancy Group
” section that follows this section.
Step 1
If you have not done so already, upgrade the PXM software to a version that supports the MPSM software
you will be using. 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.
Step 2
If you have not done so already, copy the MPSM runtime software to the switch as described in the
“
Copying Software Files to the Switch
” section in
Appendix A, “Downloading and Installing Software
MPSM runtime files are named using the following format: mpsm_t1e1_030.000.000.000.fw. The
numerals in the file name indicate the software version as described in “
Chapter 9, “Switch Operating Procedures.”
Step 3
Establish a configuration session using a user name with SERVICE_GP privileges or higher.
