Quickstart Procedures for Software Upgrades
When you upgrade the software in a switch, you should refer to the Release Notes for Cisco MGX 8850
(PXM1E/PXM45), Cisco MGX 8950, and Cisco MGX 8830 Switches, Release 5.0.00 and the Release
Notes for the Cisco MGX 8880 Media Gateway, Release 5.0.00 for the latest information. Each type of
switch card runs boot and runtime software. The recommended sequence for upgrading the software on
switch cards is as follows:
1.
boot software
2.
runtime software
Note
If you plan to upgrade PXM cards and service modules, upgrade the PXM cards first. Wait until the PXM
cards are operating in active and standby modes with the correct software before upgrading service
modules.
Note
You do not need to upgrade any software on SRM cards.
Typically, the boot software requires less frequent upgrades. Some upgrades might only require updates
to one type of switch card. The Release Notes for Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950,
and Cisco MGX 8830 Switches, Release 5.0.00 and the Release Notes for the Cisco MGX 8880 Media
Gateway, Release 5.0.00 should explain which software components require upgrading.
When you upgrade the software on a switch card, proceed as follows:
•

•
Follow the appropriate quickstart procedure for that type of upgrade
•
