Power On Self-Test; Checking Post Results - HP StorageWorks 2/32 - SAN Switch Installation Manual

Installing the SAN Switch 2/32

Power On Self-Test

Each time the switch is powered on, rebooted, or reset, the switch automatically
runs 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:
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 Activity," in Chapter 3.

activity, the error log, or CLI using the errShow command. For more
