Appendix A Downloading and Installing Software Upgrades
Quickstart Procedures for Software Upgrades
Note If you plan to upgrade PXM45 cards and AXSM or FRSM-12 cards, upgrade the PXM45 cards first. Wait
until the PXM45/B 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, and FRSM-12 cards.
Note Cisco Systems recommends that you upgrade software on one AXSM or FRSM-12 card at a time within
a switch. Wait until each AXSM or FRSM-12 card upgrade is complete before starting an upgrade on
another AXSM or FRSM-12 card.
Non-Graceful AXSM Boot Upgrades
Ungraceful upgrades disrupt all switch traffic and are usually used in lab installations where the use of
standalone cards provides no opportunity for a graceful upgrade. The quickstart procedure is provided
as an overview and as a quick reference for those who have already performed ungraceful upgrades on
the switch.
Note If you plan to upgrade PXM45 cards and AXSM 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 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, and AXSM-E cards.
