Action
Wait at least 5 seconds before installing the replacement card. Gently push
the replacement circuit pack into the shelf slot until the ejector latches come
in contact with the front of the shelf. Then push the latches in toward the
circuit pack to engage the circuit pack with the backplane connector.
While the software is being downloaded to the replacement processor card,
the yellow Init LED on the maintenance interface card (MIC) is lit. The yellow
Init LED on the MIC goes off when the software downloading is complete,
which takes approximately 12 minutes.
Note: On insertion of an inactive processor card, if the red fail LED lights on
both processors, replace the newly inserted processor.
If the automatic-in-service feature is set to on, and the circuit pack state
automatically changes to in-service (IS), skip to step 12.
From the processor equipment screen, change the state of the replaced card
to in-service:
