Upgrade Procedures for PXM Cards and Service Modules
Keep the following in mind when you use the abortrev command to abort the new runtime software
during an upgrade:
• If you enter the abortrev command on a redundant card set after the loadrev command was entered,
and while the cards are in the Loadrev Done-U state, only the standby card will be reset.
• If you enter the abortrev command on a redundant card set after you entered the runrev command,
while the cards are in the Runrev Done-U state, both the active and standby cards will be reset.
• If you enter the abortrev command on a single card, after you entered the loadrev command and
the card is in the Loadrev Done-U state, the card will not be reset.
• If you enter the abortrev command on a single card, after you entered the runrev command and the
card is in the Runrev Done-U state, will be reset.
To display the current state of the card, enter the dsprevs -sl command. The card state appears under the
Rev Chg Status column. In the following example, the PXM cards in slot 7 and 8 are in the Loadrev
Done-U state.

Caution Reverting to the previously used version of runtime software resets both PXM cards and terminates all
calls in progress.
To revert to the previously used runtime software version, use the following procedure.
Step 1 Establish a configuration session using a user name with SERVICE_GP privileges or higher.
Step 2 To display the software revisions known to the switch, enter the dspcd <slot> command. (You can also
view the revision levels with the dsprevs command.)
Replace slot with the slot number of the active card. To complete the next step, you need to know the
secondary software revision shown in the display.
