Chapter 10 Switch Maintenance Procedures
Replacing Cards
The configuration for AXSM cards is stored on the PXM45. The switch will configure the new AXSM/B
card and bring it up in standby mode. In standby mode, the card will operate as an AXSM/A card.
Step 4
Enter the dspcd or dsprev command to verify that the AXSM/B card is using the correct boot software
version.
Note
The switch automatically selects and loads the correct runtime software for the AXSM based on the
configuration for that slot. The switch does not automatically burn boot code for an AXSM. For
instructions on upgrading boot code, see
Appendix A, “Downloading and Installing Software
Step 5
If you need to replace both AXSM cards in the redundant pair, repeat Steps 1 through 4 for the other card.
Step 6
When both cards have been upgraded to AXSM/B cards, enter the enableaxsmbaps command at the
PXM prompt.
This step causes the redundant AXSM/B cards to stop emulating AXSM cards and operate as AXSM/B
cards. Once the AXSM/B cards start operating in as AXSM/B card, the cards can no longer return to
AXSM operating mode.
Replacing Service Modules
The procedure you use for replacing a service module depends on whether you are replacing the service
module with the same type of service module or with a different type. The following sections describe
the following procedures:
•
Replacing Service Modules with the Same Type of Service Module
•
Replacing Eight-Port T1 and E1 Service Modules with MPSM-8-T1E1
•
Replacing Service Modules with a Different Type of Service Module
Replacing Service Modules with the Same Type of Service Module
If a service module front or back card fails, remove the old card and insert a new card of the same type
in the same slot. If the card is a standalone card, all communications are interrupted. If the card is part
of a redundant card set, you can replace the standby card without disrupting traffic through the active
card.
The configuration for each service module is stored on the PXM. The switch automatically configures
the replacement service module and starts it up. If the card is a standalone card, the card will start up as
an active card. If the card is part of a redundant pair, the card will start up in standby mode.
Note
The switch automatically selects and loads the correct runtime software for a service module based on
the configuration for that slot. The switch does not automatically burn the boot code for a service
module.
