CAUTION:

Diagnostic tests can temporarily lock the transmit and receive speed of the links during diagnostic testing.

For information about speciﬁc diagnostic tests, refer to the latest version of the HP StorageWorks Fabric OS administrator guide or type help followed by the name of the diagnostic test.

Powering on and off

4Gb SAN Switch power is provided by the enclosure. The 4Gb SAN Switch will run POST by default each time power to the enclosure is turned on. The POST process can last as long as three minutes.

To remove power from the switch, remove the 4Gb SAN Switch from the enclosure interconnect bay.

NOTE:

Each time the 4Gb SAN Switch is powered on, its settings are restored to the last saved conﬁguration.

Interpreting LED activity

You can monitor switch activity and status by checking 4Gb SAN Switch LEDs.

There are three possible LED states: no light, a steady light, or a ﬂashing light. The steady lights and ﬂashing lights can be green or amber.

The LEDs ﬂash any of these colors during boot, POST, or other diagnostic tests. This is normal and does not indicate a problem unless the LEDs do not indicate a healthy state after all boot processes and diagnostic tests are complete. A healthy state is indicated by a steady green light. See Table 12 for details about LED activity.
