26462a Figure 24 Installing an SFP in the upper row of port slot Diagnostic Tests In addition to POST, Fabric OS includes diagnostic tests to help you troubleshoot the hardware and firmware. This includes tests of internal connections and circuitry, fixed media, and the transceivers and cables in use. The tests are implemented by command, either through a telnet session or through a console set up to the serial connection to the switch. Some tests require the ports to be connected by external cables, to allow diagnostics to verify the serializer/deserializer interface, transceiver, and cable. Some tests require loopback plugs. Diagnostic tests run at link speeds of 1, 2, 4 and 8-Gbps. IMPORTANT: Diagnostic tests might temporarily lock the transmit and receive speed of the links during diagnostic testing. For information about specific diagnostic tests, see the Fabric OS command reference manual. 8Gb SAN Switch hardware reference manual 55

xed media, and the transceivers and
cables in use. The tests are implemented by command, either through a telnet session or through a
console set up to the serial connection to the switch. Some tests require the ports to be connected by
external cables, to allow diagnostics to verify the serializer/deserializer interface, transceiver, and

Diagnostic tests run at link speeds of 1, 2, 4 and 8-Gbps.
