Adapter Module LEDs

When the ARN/DC has an optional adapter module installed, its interface LEDs are visible on the front panel. For the location of the two ARN/DC adapter module slots, see Figure 1-4 on page 1-9.

Note: The ARN base module boots to a fully operational state before bringing up adapter module interfaces.
