Base Module LEDs
The base module includes diagnostic LEDs and LAN interface LEDs, visible on
the front panel of the ARN.
Diagnostic LEDs
The base module diagnostic LEDs ( Figure 3-1 ) indicate the status of the ARN
itself. All of these LEDs light briefly when you turn on the ARN power switch.

Table 3-1 describes the base module diagnostic LEDs.
