SAN Switch 2/32 Diagnostics

Read the following sections for information on using POST and diagnostic tests.

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, refer to the HP
StorageWorks Fabric OS Procedures Version 3.0.x/4.0.x User Guide.
Note:
successfully completed and the switch should be returned to your switch supplier 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
HP StorageWorks Fabric OS Procedures Version 3.0.x/4.0.x User Guide.

Additional Diagnostic Tests

The SAN Switch 2/32 uses diagnostic tests to help troubleshoot hardware and
firmware. The diagnostic tests provided on the switch include tests of internal
connections and circuitry, fixed media, and any SFP modules and fiber optic
cables in use. The tests are implemented by command, either through a telnet
session or through a terminal set up for a Serial connection to the switch. Some
tests require the ports to be connected by external cables, to allow diagnostics to
verify the serializer/deserializer interface, and to verify the attached SFP and
cable.
All diagnostic tests are run at link speeds of both 1 Gbps and 2 Gbps. For
information about the specific diagnostic tests and how to run them, refer to the
HP StorageWorks Fabric OS Procedures Version 3.0.x/4.0.x User Guide.
