Appendix A Downloading and Installing Software Upgrades
Upgrade Procedures for PXM Cards and Service Modules
For non-graceful upgrades, the load process defines the software version to which the switch is about to
be upgraded.
shows how the revision levels change during a non-graceful upgrade.
If you are performing a graceful upgrade, use the quickstart procedure described in the “
and Service Module Runtime Software Upgrades
” section earlier in this appendix. The following
procedure provides detailed information on the load task within the quickstart procedure.
Step 1
To load the upgrade runtime software version on a PXM card or service module, enter the following
command:
mgx8850a.7.PXM.a >
loadrev
<
slot
> <
revision
>
Replace <slot> with the card slot number for the card to be upgraded, and replace <revision> with the
software version number for the update. For graceful upgrades, you can specify either the active or the
standby card. The switch software will automatically load the upgrade software on the standby card
when it is installed. The following example shows how to enter this command:
mgx8850a.7.PXM.a >
loadrev 7 4.0(0.0)
After you enter the loadrev command, the standby card comes up in the standby-U state.
You can find the software version number in 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. You can also determine the version number from the runtime
software filename as described in the “
Determining the Software Version Number from Filenames
section in
Chapter 9, “Switch Operating Procedures.”
Step 2
When prompted to confirm the command, type y and press Return to continue.
