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 for FC ports run at link speeds of 1, 2, 4 and 8 Gb/s.
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 Brocade Fabric OS Troubleshooting
and Diagnostics Guide .

Installing Field-Replaceable Units

This section lists FRUs and provides FRU installation procedures.

8/8 SAN Switch and 8/24 SAN Switch FRU units

No components in the 8/8 SAN Switch and 8/24 SAN Switch are field replaceable. If the switch
becomes inoperable, replace the entire switch.
