Interpreting port-side LEDs
System activity and status can be determined through the activity of the LEDs on the switch. There are
three possible LED states: no light, a steady light, and a flashing light. Flashing lights may be slow, fast,
or flickering. The lights are green or amber. Sometimes, the LEDs flash either of the colors during boot,
POST, or other diagnostic tests. This is normal; it does not indicate a problem unless the LEDs do not
indicate a healthy state after all boot processes and diagnostic tests are complete.
