This appendix provides the following pinout information:

Management Card Console Cable and Pinouts

Figure D-1 shows the management card console cable, and Table D-1 lists the pinouts.

Console and Auxiliary Port Signals and Pinouts

Following are the pinouts for the router card auxiliary port (Table D-2), and the router card console port (Table D-3):

Note To use the auxiliary port as a console port, you must set jumpers on the router card. See the section "Router Card Jumper Settings" in the appendix "Router Card Maintenance."

Refer to Table D-4 for a list of the pins used on the RJ-45 connector, the male/female DTE adapter, the male/female DCE adapter, and the male modem adapter used to connect terminals and modems to the Cisco hub. The connection of pins between the RJ-45 connector and the end device depends on the type of cable used, either straight or rolled. A straight cable connects pin 1 to pin 1, pin 2 to pin 2, and so on. A rolled cable connects pin 1 to pin 8, pin 2 to pin 7, and so on. The Cisco 2517 and Cisco 2519 ships with a rolled cable. Refer to Table D-5 for the cable and adapter configurations that can be used to connect terminals and modems to the Cisco 2517.

Table D-4: Pins for the RJ-45 Connector, M/F DTE, M DCE, and MMOD Adapters

¹ The FDTE adapter that is available through Cisco is labeled "Terminal."
² The MMOD adapter that is available through Cisco is labeled "Modem."

Table D-5: Connection Configuration

Router Card Port	RJ-45 Cable Type	DB-25 Adapter	End Device

Console/auxiliary	Straight	MDTE¹	Modem
Auxiliary/console	Rolled	MMOD¹	Modem

¹ Modify by removing DB-25 pin 6 and replacing it in the Pin 8 position.

BRI Port Pinout and Signals

Table D-6 lists the router card BRI port pinout and signals.

Table D-6: BRI Port Pinout (RJ-45)

Pin¹	TE¹	NT²	Polarity
3	Transmit	Receive	+
4	Receive	Transmit	+
5	Receive	Transmit	-
6	Transmit	Receive	-

Caution To prevent damage to the system, make certain you connect the BRI cable to the BRI connector only and not to any other RJ-45 connector. The console, auxiliary, Token Ring, and BRI ports all use RJ-45 connectors.

¹ TE refers to terminal terminating layer 1 aspects of TE1, TA, and NT2 functional groups.
² NT refers to network terminating layer 1 aspects of NT1 and NT2 functional groups.

Token Ring Pinout

Table D-7 lists the pinout for the Token Ring interface ports.
