contained in packaging for the frame ID that you are working on.
2. Find the card position for the IOA or IOP that you are removing and select Concurrent maintenance.
Attention: If multiple resources are shown with the same card position, one or more of these
resources will show a status of Missing (″?″ after the description). Only one resource will be listed as
not missing. Select this resource for the concurrent maintenance operation.
3. A listing of the power domain is shown. Find the IOA or IOP that you are removing and select Power
off domain. Everything within the IOA’s or IOP’s power domain will be powered off .
4. To see the status of the power domain, select Display power status.
5. Find the IOA or IOP that you are removing and select Toggle LED blink off/on.
6. Remove the cover to access the card that you are removing from the system. See FC 5078, FC
0578, FC 5088, FC 0588 - Covers.
