Preparing a Card for Replacement
To minimize service disruptions, traffic currently being processed by a failing or failed circuit card should be switched
to another card. You have the following options based on the type of card being replaced:
to another card. You have the following options based on the type of card being replaced:
MIO/UMIO – If the active MIO/UMIO fails, a switchover to the standby MIO/UMIO is automatic. In the event
that an issue arises that is not severe enough for the system to perform an automatic switchover, a manual
switchover can be invoked by executing the Exec mode card switch from <5 or 6> to <6 or 5> command.

DPC/UDPC and DPC2/UDPC2 – An Exec mode card busy-out slot_number command moves processes from
the source DPC/UDPC to the destination DPC/UDPC, or disables the DPC/UDPC from accepting any new
calls. When busy-out is enabled, the DPC/UDPC stops receiving new calls but continues to process calls until
they are completed. The busy-out procedure is completed in background.

FSC – The FSCs are configured for n+1 redundancy. When an active FSC fails, an automatic switchover is
made to the standby FSC. At least one FSC must be in standby mode prior to initiating a switchover. In the
event that an issue arises that is not severe enough for the system to perform an automatic switchover, a manual
switchover can be invoked by executing the Exec mode card switch from slot_number to slot_number
command.

Important:
An FSC-200GB (equipped with two 200GB SSDs) can be replaced with an FSC-400GB (equipped
with a single 400GB SSD) only if the StarOS release supports the non-RAID 0 configuration of the FSC-400GB.
Cards other than MIO/UMIO that are in either the Active or Standby modes should be halted prior to removal. Halting
these cards places them into the “offline” mode. In this mode, the card is unusable for session processing as either an
active or redundant component. If a card in the active mode is halted, its tasks, processes, or network connections will
be migrated or switched to a redundant component prior to entering the offline mode.

Initiate a manual card migration by entering the Exec mode card halt slot# command.
Verify that the migration was successful by entering the Exec mode show card table command. Check the entry in the
Oper State column next to the card that was just halted. Its state should be Offline. If the card was in active mode prior
to the execution of this command, the state of the redundant component associated with it should now be Active.

to the execution of this command, the state of the redundant component associated with it should now be Active.
All status LEDs on the halted card should be OFF when a card is offline and ready to be replaced.
Caution:
Attempting to replace a circuit card that has not been taken offline may result in spurious error
messages and unexpected behavior that may initiate reload of other cards.
