Chapter 10 Switch Maintenance Procedures
Decommissioning an AXSM Slot
Note The SRME/B line configuration parameters (which are used only for bulk distribution) are similar to that
of the SRM-3T3, but there are some differences. Replacing a SRM-3T3 with an SRME/B sets all
parameters to the defaults assigned to the SRME/B.
If this is a redundant configuration, the SRME/B will start up in standby state. If this is a standalone
configuration, the SRM should come up in the active state, and the standalone replacement is complete.
Step 3 If this is a redundant configuration, use the switchcc command to switch control from the active PXM
and SRM cards to the standby PXM and SRM cards. The new SRME/B becomes the active card and the
other SRM can be replaced.
Step 4 If this is a redundant configuration, replace the current standby SRM front card with an SRME/B.
Replacing RPM Cards
If you have properly initialized an RPM card as described in the “Initializing RPM Cards” section in
Chapter 6, “Preparing RPM Cards for Operation.” the configuration for the RPM card is stored on the
PXM hard disk.
To replace a standalone RPM card, remove the old card and insert a new card of the same type in the
same slot. The switch will automatically configure the card and start it up.
Note RPM-PR and RPM-B cards are not interchangeable. When replacing an RPM-PR card, you must replace
it with another RPM-PR card. If you want to change types of cards, you must first decommission the slot
as described in the “Replacing PXM1E-4-155 Cards with PXM1E-8-155 Cards” section which appears
later in this chapter.
To replace an RPM card that is configured for redundancy, first switch control to the standby card, then
replace the card while it is operating in standby mode. If the card you are replacing has failed, there is
no reason to switch cards, as the failure should have triggered a switch to the standby card. If you need
to switch cards, enter the softswitch command as described in the “Switching Between Redundant RPM
Cards” section in Chapter 9, “Switch Operating Procedures.”
Note After you replace a card that is configured for redundancy, it starts up in standby mode. If the active card
is configured to operate as a standby card for multiple RPM cards, enter a softswitch command so that
the active card returns to its normal standby state.
Decommissioning an AXSM Slot
When an AXSM card is installed and configured, the configuration is associated with a specific slot
number and stored on the PXM45 card. If you replace the AXSM with another card of the same type,
the new card will start operating with the established configuration. Any configuration which has been
used previously on that card will be discarded, because the configuration is assigned to the slot, not the
physical card.
