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: ■ Preliminary POST diagnostics ■ Initialization of operating system ■ Initialization of hardware ■ Diagnostic tests are run on a number of functions, including circuitry, port functionality, memory, parity, statistics counters, and serialization 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. Note: For more information about beaconing, refer to the HP StorageWorks Fabric OS Procedures Version 3.0.x/4.0.x User Guide. Checking POST Results Check the success/fail results of the diagnostic tests run during POST via LED activity, the error log, or CLI using the errShow command.

SAN Switch 2/32 Installation Guide
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:
■
Preliminary POST diagnostics
■
Initialization of operating system
■
Initialization of hardware
■
Diagnostic tests are run on a number of functions, including circuitry, port
functionality, memory, parity, statistics counters, and serialization
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.
Note:
For more information about beaconing, refer to the
HP StorageWorks Fabric
OS Procedures Version 3.0.x/4.0.x User Guide
.
Checking POST Results
Check the success/fail results of the diagnostic tests run during POST via LED
activity, the error log, or CLI using the
errShow
command. For more
information about error messages, refer to the
HP StorageWorks
Fabric OS
Version 3.0.x/4.0.x Reference Guide.
