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.
