Table 3-2 describes the LEDs on the power supply side of the switch.
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: If the switch prompt does not display when POST completes, POST was not successfully
completed and the switch should be returned to your HP account representative for repair.
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.
