Status

The Status LED indicates the status of a firmware download. The LED will increment from left to right while firmware is being downloaded. It will be dark during normal operation.

Diagnostic

The Diagnostic LED is used to diagnose any problem on the DES-5024. If any part of the DES-5024 fails the POST or if a problem occurs the Diagnostic LED displays a code indicating the problem. See Chapter 6 for the meaning of the LED code and a recommended action.

Utilization

The Utilization LED indicates the utilization of the DES-5024’s CPU. It increments from left to right. The higher the number the greater the utilization.
