Managing the SAN Switch 2/16 Diagnostic Tests This section contains information on using POST and diagnostic tests. Interpreting POST Results Each time the switch is powered on or reset, the it 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 3.1.x/4.1.x User Guide. Note: If the switch prompt does not display when POST completes, POST did not successfully complete 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 3.1.x/4.1.x User Guide. Diagnostic Tests Diagnostic tests are provided to help troubleshoot the hardware and the 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, as well as 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 3.1.x/4.1.x User Guide. Note: The transmit and receive speed of the links may be temporarily locked to a specific speed during diagnostic testing. SAN Switch 2/16 Version 3.1.2 Installation Guide 65

SAN Switch 2/16 Version 3.1.2 Installation Guide

Diagnostic Tests

This section contains information on using POST and diagnostic tests.

Interpreting POST Results

Each time the switch is powered on or reset, the it 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

StorageWorks Fabric OS Procedures Version 3.1.x/4.1.x User Guide

Note:

If the switch prompt does not display when POST completes, POST did not

successfully complete 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 3.1.x/4.1.x User Guide

Diagnostic Tests

Diagnostic tests are provided to help troubleshoot the hardware and the 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, as well as 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 3.1.x/4.1.x User Guide

Note:

The transmit and receive speed of the links may be temporarily locked to a

specific speed during diagnostic testing.
