Powering on and off
8Gb SAN Switch power is provided by the enclosure. The 8Gb SAN Switch runs POST by default
each time power to the enclosure is turned on. The POST process can take up to three minutes.
To remove power from the switch, remove the 8Gb SAN Switch from the enclosure interconnect
bay.
NOTE:
Each time the 8Gb 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 8Gb 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.
LED indicators
All 8Gb SAN Switch LEDs are located on the port side (see
