Appendix A Downloading and Installing Software Upgrades
Upgrade Procedures for PXM45, AXSM, and FRSM-12 Cards
Replace <slot> with the slot number of a standalone AXSM/FRSM-12 card, or an AXSM/FRSM-12 card
operating in standby mode. Replace <revision> with the software revision number to which you are
upgrading. For example:
pop20one.7.PXM.a > burnboot 1 2.1(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 AXSM or FRSM-12 card 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 AXSM or FRSM-12 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.
Step 5 To confirm that the AXSM or FRSM-12 card is now using the correct boot code, enter the dspcd <slot>
command. The Boot FW Rev row in the display should show the new revision as shown in the following
example:
8850_NY.7.PXM.a > dspcd 1

Aborting a Runtime Software Upgrade
After upgrading PXM45, AXSM, or FRSM-12 runtime software, you can revert to the previously used
version of software at any time, as long as you have not committed to the new software version with the
commitrev command (which is described in the next section).
Caution Reverting to the previously used version of runtime software resets both PXM45 cards and terminates
all calls in progress.
