LED activity

System activity and status can be determined through the activity of the LEDs on the Extension

Switch.

There are three possible LED states:

• No light

• Steady light

• Flashing light

Active lights are in one of the following colors:

• Green

• Amber

The status LEDs may display solid amber or flash 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.
