Non-Graceful AXSM Runtime Software Downgrades
AXSM runtime software downgrades are always non-graceful when the PXM45 runtime software is also
downgraded (because the PXM45 downgrade requires a clearing of the configuration). The quickstart
procedure provides an overview of how to downgrade the AXSM software after the PXM45 runtime
software has been downgraded.

Quickstart Procedures for Software Downgrades
Purpose
Establish a CLI session with the active PXM card using a user
name with SERVICE_GP privileges.
Save the current switch configuration.
See the
"Saving a
Configuration"section in
Operating Procedures."
This step gives you the option to upgrade to the software version
from which you are downgrading and use the former
configuration.
Copy the boot and runtime files you want to use to the switch.
Also copy the saved configuration file from the C:CNF directory
to a remote workstation so you have a backup file if something
happens to the hard disk.
See the
"Copying Software Files to the
this appendix.
Clear the current configuration.
See the
"Clearing a Switch
"Switch Operating Procedures."
Select the runtime firmware version the switch will use on the
PXM card and restart the switch with that firmware. For example:
sysVersionSet "002.001.000.000"
Note that these commands must be entered at the PXM backup
boot prompt: pxmbkup>.
See the
"Initializing the
Switch" section in
"Configuring General Switch

Quickstart" section in
