Installing and Operating BayStack ARN Routers
3-2 114200 Rev. A
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 (F
igure 3-1) indicate the status of the ARN
itself. All of these LEDs light briefly when you plug the ARN into the wall outlet
and turn on the power switch.
