Expansion Module Leds; Ethernet Leds; Token Ring Leds - Nortel 114200-E Installation And Operating

Expansion Module LEDs

When the ARN has an installed expansion module, its interface LEDs are visible
on the front panel. For the location of the optional ARN expansion module, see
Figure 1-4 on page 1-9.
Note: The ARN base module boots to a fully operational state before bringing
up expansion module interfaces.
