1. Verify that the LEDs on the Embedded Switch Module indicate a healthy Embedded Switch
Module state. LED patterns are described in “Interpreting LED activity.”
If one or more LEDs do not display a healthy state, verify that the LEDs are not set to beacon.
Use the Embedded Switch Module CLI switchShow command or Web Tools to verify the LED
state. For information about how to turn beaconing on and off, see the Fabric OS
Administrator’s Guide or the Web Tools Administrator’s Guide.
2. Use the PRIMERGY BX900 Management Blade GUI to verify that the Embedded Switch Module
is working correctly.
For details, refer to the PRIMERGY BX900 S1 Basic Unit Operating Manual.
3. Review the system log for errors.
Any errors detected during POST are written to the system log. Access this log through the
Module’s CLI errShow command. For information about this command, see the Fabric OS
Command Reference. For information about error messages, see the Fabric OS Message
Reference.
Diagnostic tests
In addition to POST, Fabric OS includes diagnostic tests to help troubleshoot the hardware and the
firmware including tests of internal connections and circuitry, fixed media, and the transceivers and
cables in use.
Initiate diagnostic tests with the command line using a Telnet session or a terminal set up with 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, transceiver, and cable. For
information on available diagnostic tests, enter diagHelp.
All diagnostic tests are run at link speeds of 1 Gbps, 2 Gbps, 4 Gbps, and 8 Gbps.
NOTE
Diagnostic tests can temporarily lock the transmit and receive speed of the links during diagnostic
testing.
