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 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, see the Fabric OS Troubleshooting and Diagnostics
Guide .
Brocade 6520 management
You can use the management functions built into the Brocade 6520 to monitor the fabric topology,
port status, physical status, and other information to help you analyze switch performance and to
accelerate system debugging.
The Brocade 6520 automatically performs power-on self-test (POST) each time it is turned on. Any
errors are recorded in the system error log. For more information about POST, see
“POST and boot
specifications” on page 19.
