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.

1 Pins 5 and 4 are connected.


Console and Auxiliary Port Signals and Pinouts

Following are the pinouts for the router card auxiliary port (see 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 2518. 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 2518 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 2518.

1 The FDTE adapter that is available through Cisco is labeled "Terminal."
2 The MMOD adapter that is available through Cisco is labeled "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 TE2 NT3 Polarity
3 Transmit Receive +
4 Receive Transmit +
5 Receive Transmit --
6 Transmit Receive --

1 Pins 1, 2, 7, and 8 are not used.
2 TE refers to terminal terminating layer 1 aspects of TE1, TA, and NT2 functional groups.
3 NT refers to network terminating layer 1 aspects of NT1 and NT2 functional groups.

fig_1.gif 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, and BRI ports all use RJ-45 connectors.
