Chapter 10 Switch Maintenance Procedures
Decommissioning an AXSM Slot
Replacing RPM Cards
If you have properly initialized an RPM card as described in the “
” 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
” 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.
If you want to use a previously configured AXSM slot for a different type of AXSM card, you must first
decommission the slot to remove the existing configuration. Otherwise, the switch will attempt to run
the old configuration on the new card, and the new card will not operate correctly.
Note
If you enter the cnfpnportsig command to change default port values, you must run the delpnport
command to delete the port from the PXM45. If you do not run delpnport on the PXM45, the port will
remain in a provisioning state on the PXM45.
To decommission a slot, you need to remove the existing connections, partitions, and ports as described
below.
