LED Descriptions

LEDs on the ARN front and back panels provide information about how the ARN
is operating. The following sections describe the LEDs on the ARN base modules,
expansion modules, adapter modules, and the ARN back panel.

Base Module LEDs

The ARN base module LEDs include diagnostic LEDs and either Ethernet or
token ring interface LEDs.

Diagnostic LEDs

The base module diagnostic LEDs
itself. All of these LEDs light briefly when you plug the ARN into the wall outlet
and turn on the power switch.
