Interpreting LED Activity

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.

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 10 on page 62 for details about

LED activity.
