5 DIAGNOSTICS Overview The 2250 switch model is designed for maintenance-free operation, and contains self-diagnostic capabilities that provide switch status and operating statistics. In the case of a failure, the self-diagnostics aid in isolating the problem. Each 2250 switch has the following loopback paths incorporated into the switch hardware: • An internal loopback path test that checks internal Fibre Channel port logic functions, and the paths between the interfaces and central memory. • An external loopback path test that checks installed fiber optic cables and port fault isolation in cross-port configurations, and also checks the main board, fixed media, and the GBIC module in each port. This test requires ports to be connected by external cables. 77
