Interpreting LED activity
You can monitor switch activity and status by checking the 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.
