Interpreting POST Results

Each time the switch is powered on or reset, the switch automatically performs POST, a one minute
system check during which the port status LEDs flash different colors.
To determine whether POST completed without errors, verify that all LEDs return to a normal state
after POST is complete. If one or more LEDs do not return to a normal state, and this is not due to
the switch being set to beacon, see Interpreting LED Activity on page 3-1 (for more information
about beaconing, refer to the Fabric OS Procedures Guide).
Note:
Any errors detected during POST are written to the system log, accessible through the errShow
command. For more information about error messages, refer to the Fabric OS Reference.
