Appendix A Downloading and Installing Software Upgrades
Quickstart Procedures for Software Upgrades
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.
Graceful RPM-PR Boot Software Upgrades
The RPM-PR card supports graceful boot software upgrades when 1:n redundancy is established in the
switch between RPM-PR cards. Boot software is generally upgraded less often than runtime software,
so be sure to compare the recommended boot software version with the boot software running on your
RPMs before starting an upgrade. The correct boot software might already be installed.
The following quickstart procedure describes how to upgrade redundant RPM-PR cards.
Note Redundancy must be established before you use this procedure. If redundancy has not been configured
between two RPM-PR cards, upgrade each RPM-PR card using the procedure in “Non-Graceful
RPM-PR Boot Software Upgrades,” which appears later in this chapter. To add redundancy to an
RPM-PR card, see the “Establishing Redundancy Between Two RPM-PR Cards” section in Chapter 5,
“Preparing RPM-PR Cards for Operation.”
Command Purpose
Step 1
ftp Copy the boot and runtime files you want to use to the switch.
See the “Copying Software Files to the Switch” section, which

Step 3
saveallcnf This optional step saves the current configuration to the hard disk.
See the “Saving a Configuration” section in Chapter 7, “Switch
Operating Procedures.”
Step 4
burnboot <slot> <revision>
dspcd <slot>
Burn the boot software on the standby AXSM or FRSM-12 card
by specifying the slot number of the standby card. For example:
M8850_LA.7.PXM.a > burnboot 1 3.0(0.0)
See the “Upgrading Boot Software on an AXSM or FRSM-12
Card” section, which appears later in this appendix.
