Maintenance and Diagnostic Tests
The FC 16B does not require any regular physical maintenance, and is
designed to minimize the chance of failure, including diagnostic tests and
field-replaceable units.
Diagnostic tests are provided to help troubleshoot the hardware and the
firmware. The diagnostic tests provided on the switch include tests of
internal connections and circuitry, fixed media, and any SFP modules and
fiber optic cables in use. The tests are implemented by command, either
through a telnet session or through a terminal set up for a 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, as
well as the attached SFP and cable.
All diagnostic tests are run at link speeds of both 1 Gbps and 2 Gbps. For
detailed information about the specific diagnostic tests and how to run
them, refer to the Fabric OS Procedures Guide.
