NOTE
Each SFP has a 10-pad gold-plated PCB-edge connector on the bottom. The correct position to
insert an SFP into the upper row of ports is with the gold edge down. The correct position to insert
an SFP into the lower row of ports is with the gold edge up.

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 run at link speeds of 1, 2, 4 and 8 Gbps depending on the speed of the link being
tested.
NOTE
Diagnostic tests might temporarily lock the transmit and receive speed of the links during
diagnostic testing.
For information about specific diagnostic tests, see the Fabric OS Troubleshooting and Diagnostics
Guide.
