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
for details about LED activity.
