Appendix A Downloading and Installing Software Upgrades
If you have not done so already, establish a CLI session with the PXM card using the CP port on the
Step 1
PXM-UI-S3 or PXM-UI-S3/B back card and a user name with CISCO_GP privileges.
Step 2 If you have not done so already, change to PXM Backup Boot mode as described in the
PXM Backup Boot
Step 3 To burn the boot software on the PXM, enter the sysFlashBootBurn command as follows:
pxm45bkup> sysFlashBootBurn "path/filename"
Caution If the card is removed or reset, or if switch power is interrupted during the boot software upgrade, the
upgrade will not complete, the card will not operate, and the card must be returned to Cisco for repair.
Replace filename with the complete path to the boot file on the PXM45 hard drive. For example:
pxm45bkup> sysFlashBootBurn "C:FW/pxm45_004.000.000.201_bt.fw"
When the switch prompts you to confirm this action, type y and press Return.
Step 4
When the boot code burning process is complete, the switch displays a message similar to the following
example:
Flash download completed ...
value = 0 = 0x0
Step 5 When the boot code has been burned, reset the card with the reboot command. For example:
pxm45bkup> reboot 2
Beginning with Release 4.0, you must enter reboot 2. For all prior releases, enter reboot.
Note
Be patient and wait for the Login prompt to appear.
When the Login prompt appears, log in to the switch as you do at the beginning of a CLI session. The
Step 6
switch prompt should appear.
