Notes

To check cabling, look for bent pins, loose wires, loose cable shielding, or loose cable casing.

Fibre Channel arrays use SFP connectors to attach the array to hosts and expansion units. Each Fibre Channel I/O expansion module has two SFP ports. These ports are labeled Loop A or Loop B.

Prior to replacing a chassis, try the following:

--Reseat the FRU that is not operating correctly.

--Swap the questionable FRU with a known-good FRU from the same array.
