Interpreting POST Results
POST is a system check that is performed each time the switch is powered on, rebooted or reset,
and during which the LEDs flash different colors. Any errors that occur during POST are listed in
the error log.
To determine whether POST completed successfully, and whether any errors were detected:

Verify that the switch LEDs indicate that all components are healthy (refer
page 3-2
and
Table 3-2 on page 3-4
If one or more LEDs do not display a healthy state:
1.
Verify the LEDs on the switch are not set to "beacon" (this can be determined through
the switchshow command). For information about how to turn beaconing on and off,
refer to the Brocade Fabric OS Procedures Guide.
2.
Follow the recommended action for the observed LED behavior, as listed in
Table 3-1 on page 3-2
or
Verify the switch prompt displays on the terminal of a computer workstation connected to
the switch.
If the switch prompt does not display when POST completes, press ENTER. If the switch
prompt still does not display, try opening another telnet session or accessing through
another management tool. If this is not successful, the switch did not successfully
complete POST; contact your switch supplier for repair.
Review the switch system log for errors.
Any errors detected during POST are written to the system log, accessible through the
errshow command.For information about accessing the error log, refer to Brocade Fabric
OS Procedures Guide. For information about error messages, refer to the Brocade
Diagnostic and System Error Message Reference.
