the startup process is
not complete, or the

occurred on one or
more ports. Errors might be listed in
the error log. See the
Brocade Diagnostic and
System Error Message
Reference
for more
information.
Interpreting POST
Each time you power on or reset the switch, the switch automatically performs a
POST, a one-minute system check. The LEDs flash during a POST, but all LEDs
should return to a normal state when the POST is complete.
To determine whether a POST completed without errors, verify that all LEDs return
to a normal state after the POST is complete. If one or more LEDs continue to
flash, see “Interpreting LED activity” on page 15. Verify that the flashing is not due
to the switch being configured to beacon.
Note: The switchBeacon command sets the switch beaconing mode on or off if
the operand is 1 or 0 respectively. When you turn on beaconing mode, the
port LEDs flash orange in a running pattern from port 0 - port 15, port 15 -
port 0, and then back to port 15 again.
For more information about the switchBeacon command, see the Brocade Fabric
OS Reference .
Note: If the switch prompt does not display, or if the Power Supply LED or the
Switch Status LED flashes, the POST did not successfully complete. You
should then return the switch for repairs.
If errors are detected during a POST, error messages are written to the system
error log. You can view this error log by using the
errShow command. For
information about error messages, see the Brocade Diagnostic and System Error
Message Reference .
