Table A-3 VWIC LEDs

LED	Color	Description

Loopback	Amber	A loopback or line state is detected or is manually set by the user.

	Off	Normal operation.

Alarm	Amber	A local or remote alarm state.

	Off	Normal operation.

Carrier Detect	Green	A carrier has been detected and the internal DSU/CSU in the WAN
		interface card is communicating with another DSU/CSU. This LED is on
		during normal operation.

	Off	No carrier has been detected.

Note In a redundant configuration, when the relays of the VWIC open, the Carrier Detect LED on the T1 ports will remain lit and the Alarm LED will also come on. Therefore, the inactive router will show both the Carrier Detect light and the Alarm light, while the active router will show only the Carrier Detect light.
