RJ-45 Connector

Console Port Mode 2 Signaling and Pinouts (Sup2 Only)

Table B-11lists the pinouts for the Supervisor Engine 2 console port mode switch in mode 2 (switch in the out position). In this mode, you can connect a terminal to the supervisor engine using a Catalyst 5000 family Supervisor Engine III console cable and adapter (not provided). For instructions, see “Supervisor Engine 2” in the “Connecting a Terminal” section on page 3-9.

Table B-11 Console Port Pinouts (Supervisor Engine 2, Port Mode Switch Out)

Console Port		Console Device
Pin (Signal Name)		Input/Output
1	(RTS)1	Output
2	(DTR)	Output
3	(RxD)	Input
4	(GND)	GND
5	(GND)	GND
6	(TxD)	Output
7	(DSR)	Input
8	(CTS)1	Input

1. Pin 1 is connected internally to Pin 8.

RJ-45 Connector

The RJ-45 connector is used to connect a Category 3, Category 5, Category 5e, or Category 6 FTP from the external network to the module interface connector. (See Figure B-2.) Table B-12lists the connector pinouts and signal names for a 10/100BASE-T crossover (MDI-X) cable. Figure B-3shows a schematic of the 10/100BASE-T crossover cable. Table B-13lists the connector pinouts and signal names for a 1000BASE-T crossover (MDI-X) cable. Figure B-4shows a schematic of the 1000BASE-T crossover cable.

Caution Category 5e and Category 6 cables can store high levels of static electricity because of the dielectric properties of the materials used in their construction. Always ground the cables (especially in new cable runs) to a suitable and safe earth ground before connecting them to the module.

Caution To comply with Telcordia GR-1089 intrabuilding, lightning-immunity requirements, you must use foil-twisted pair (FTP) cable that is properly grounded at both ends.

Inline power for IP phones uses connector pins 1, 2, 3, and 6 in a Category 5, Category 5e, or Category 6 cable to transmit power (6.3 W) from the router. This method of supplying power is sometimes called phantom power because the IP phone power travels over the same pairs of wires used to transmit the Ethernet signals. The IP phone voltage is completely transparent to the Ethernet signals and does not interfere with their operation.
