Step 5 To verify that the new RPM-PR files have been transferred to the switch, log into the switch and display
the contents of the E:/RPM directory.
For more information on browsing the switch file system, see the “Installing SCT Files” section, which
appears earlier in this appendix.
Upgrade Procedures for PXM45, AXSM, and FRSM-12 Cards
The following sections describe procedures that support upgrades to PXM45, AXSM, and FRSM-12
cards. For complete upgrade procedures, see the “Quickstart Procedures for Software Upgrades” section,
which appears earlier in this appendix. The procedures in this section detail some of the tasks listed in
the quickstart procedures.
Upgrading PXM45 Boot Software
This section describes how to upgrade the PXM45 boot software on a single PXM45 card. If you are
performing a graceful upgrade, use the quickstart procedure described in “Graceful PXM45 Boot
Upgrades,” which appears earlier in this appendix. The following procedure provides detailed
information on the upgrade task within the quickstart procedure.
Step 1 If you have not done so already, establish a CLI session with the PXM45 card using the CP port on the
UI-S3 back card and a user name with CISCO_GP privileges.
Step 2 If you have not done so already, change to PXM45 Backup Boot mode as described in the “Changing to
PXM45 Backup Boot Mode” section in Appendix B, “PXM45 Backup Boot Procedures.”.
Step 3 To burn the boot software on the PXM45, enter the sysFlashBootBurn command as follows:
pxm45bkup> sysFlashBootBurn “filename”
Replace filename with the complete path to the boot file on the PXM45 hard drive. For example:
pxm45bkup> sysFlashBootBurn "C:FW/pxm45_003.000.000.000_bt.fw"
Step 4 When the switch prompts you to confirm this action, type y and press Return.
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
Be patient and wait for the Login prompt to appear.
Step 6 When the Login prompt appears, log in to the switch as you do at the beginning of a CLI session. The
switch prompt should appear.
Step 7 To confirm that the PXM45 card is now using the correct boot code, enter the dspcd command.
