Upgrading Boot Software On Service Modules - Cisco MGX 8850 (PXM1E/PXM45) Configuration Manual

Appendix A Downloading and Installing Software Upgrades
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 <slot> with the slot number of a standalone PXM card, or a PXM card operating in standby
mode. Replace <revision> with the software revision number to which you are upgrading. For example:
pop20one.7.PXM.a > burnboot 8 3.0(0.0)
Step 4 When prompted to confirm the upgrade, type y and press Return.
After you confirm the upgrade, the new boot code is burned into the PXM and the card is reset. Be
patient, the card reset takes some time. You can enter the dspcds command to display the status of the
PXM card. At first, the status may show that the card slot is empty or the card is rebooting. Reenter the
command periodically to see the current status of the card. When the card status returns to active or
standby, you are ready to continue.
To confirm that the PXM card is now using the correct boot code, enter the dspcd <slot> command. The
Step 5
Boot FW Rev row in the display should show the new revision as shown in the following example:
M8950_SF.7.PXM.a > dspcd 7
M8950_SF
MGX8950 (JBP-2)

Upgrading Boot Software on Service Modules

The upgrade procedure for the boot software on a single service module is the same for graceful and
non-graceful upgrades. The difference between the graceful and non-graceful upgrades is the sequence
of commands before and after the upgrade on a single card. For information on the proper sequence for
graceful upgrades, see the
appendix.
To upgrade service module boot software, use the following procedure.
