Quickstart Procedures for Software Upgrades
When you upgrade the software in a switch, you should refer to the Release Notes for Cisco MGX 8850
and MGX 8830 Software Version 3 (PXM45/B and PXM1E) or the Release Notes for Cisco MGX 8950
Software Version 3 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. PXM45 boot software
2. PXM45 runtime software
3. AXSM and FRSM-12 boot software
4. AXSM and FRSM-12 runtime software
5. RPM-PR boot software
6. RPM-PR runtime software
Note If you plan to upgrade PXM45 cards and AXSM or FRSM-12 cards, upgrade the PXM45 cards first. Wait
until the PXM45 cards are operating in active and standby modes with the correct software before
upgrading AXSM or FRSM-12 cards. The software version used by the PXM45/B cards should be equal
to or later than the version used on the AXSM, AXSM/B, AXSM-E. AXSM-32-E, or FRSM-12 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 and MGX 8830 Software Version 3
(PXM45/B and PXM1E) or the Release Notes for Cisco MGX 8950 Software Version 3 should explain
which software components require upgrading.
When you upgrade the software on a switch card, proceed as follows:
• Decide whether you are performing a graceful or non-graceful upgrade
• Follow the appropriate quickstart procedure for that type of upgrade
• For additional information on a task within a quickstart procedure, see the appendix section to which
