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 serial
console 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 2, 4, 8, 10, or 16 Gbps depending on the speed of the link
being tested and the type of port.
NOTE
Diagnostic tests might temporarily lock the transmit and receive speed of the links during diagnostic
testing.
For information about specific diagnostic tests, refer to the
Fabric OS Troubleshooting and
Diagnostics Guide
