Table 5-12lists the RJ-45 auxiliary port signals for the NPE-G1.

Table 5-12		Auxiliary Port Signals for the NPE-G1
Pin1	Signal		Direction	Description
1	RTS		Out	Ready To Send
2	DTR		Out	Data Terminal Ready
3	TXD		Out	Transmit Data
4	RING2		In	Ring Indication
5	GND		—	Signal Ground
6	RXD		In	Receive Data
73	DSR/DCD(RLSD)		In	Data Set Ready/Data Carrier Detect (Receive Line Signal

1.Any pin not referenced is not connected.

2.RING is not supported on Cisco-supplied adapters. To use this pin, you must create a customized cable.

3.Pin 7 can be used as a DCD input for connection to a modem. The RJ-45-to-DB-25F adapter maps DCD to this pin when used with a straight-through cable.

Fiber Optic Cleaning Information

We strongly recommend cleaning all optical fiber connections before reconnecting optical cables to equipment. For information about cleaning optical connectors, see the Inspection and Cleaning Procedures for Fiber-Optic Connections document and the Compressed Air Cleaning Issues for Fiber-Optic Connections document.
