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 "."

Refer to 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 for the cable and adapter configurations that can be used to connect terminals and modems to the Cisco 2517.

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

³NT refers to network terminating layer 1 aspects of NT1 and NT2 functional groups.

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.

Token Ring Pinout

lists the pinout for the Token Ring interface ports.
