Power-On Self Test; Checking Post Results - HP StorageWorks 2/16 - SAN Switch Installation Manual

Installing the SAN Switch 2/16

Power-On Self Test

Each time the switch is powered on, rebooted, or reset, the switch automatically
runs a Power-On Self Test (POST). During POST the port status LEDs flash,
verifying that the switch is operating properly. POST completes in approximately
six minutes, with total boot time approximately seven minutes.
POST runs through the following test cycles:
For example, if the switch prompt does not display when POST completes, POST
was unsuccessful. Contact your authorized HP switch supplier for more
information.
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
