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 enable 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

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.
8/40 SAN, FCoE Converged Network, and 1606 Extension SAN Switch FRU units
Replace the power supply and fan assembly unit.
Verifying fan assembly FRU replacement
To determine if a fan assembly requires replacing, do any of the following:
•
Observe the system status LED. If the system status LED is flashing amber and green, it
could indicate that the fan has failed. The green power supply/fan LED flashes in the event
