Connector and Cable Specifications

This appendix provides the following cabling and pinout information for the Cisco IAD1101 integrated access device:

Note This appendix specifies pinouts only for the pins used. Pins not listed in the tables in this appendix are not connected.

Console Port Signals and Pinouts

Use the yellow Ethernet (straight) cable and RJ-45-to-DB-9 female DTE adapter to connect the console port to the serial port on a Windows NT workstation with EMS and Dial-up Networking installed. Table B-1 lists the pinouts for the asynchronous serial console port, the RJ-45-to-DB-9 female DTE adapter, and the workstation serial port.

Note To configure your Windows NT workstation for Dial-up Networking access to the Cisco IAD1101 through the console port, see the RS-232 Connection application note.
