Figure 34 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 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 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. 8-Gb SAN Switch Hardware Reference Guide 73

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
