Purpose
At the backup boot prompt, enter the sysPxmRemove command:
This step prevents the active card from resetting the standby card
while you are working with it.
Burn the boot code. Remember to enter quotation marks before
and after the boot software filename, and specify the complete
path. For example:
sysFlashBootBurn "C:FW/pxm1e_004.000.000.201_bt.fw"
Note Remember to enter quotation marks before and after the
boot software filename. The filename you use depends on
the release to which you are upgrading. For more
information, refer to the Release Notes for Cisco MGX
8850 (PXM1E/PXM45), Cisco MGX 8950, and Cisco
MGX 8830 Switches, Release 5.0.00 and the Release
Notes for the Cisco MGX 8880 Media Gateway, Release
5.0.00.
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.
See the "Upgrading PXM Boot Software from Releases Prior to
3.0.10" section later in this appendix.
Establish a CLI session with the active PXM card (which is the
non-upgraded card). Use the CP port on the PXM-UI-S3 or
PXM-UI-S3/B back card and a user name with CISCO_GP
privileges.
Switch the roles of the active and standby cards so you can
upgrade the non-upgraded card in standby mode.
Change to the PXM Backup Boot mode.
Note that the software versions 3.0 and earlier require you to
press Return during the reboot sequence to enter backup boot
mode.
