Console and Auxiliary Port Signals and Pinouts
Ethernet Cable Assembly and Pinouts
Dual T1/PRI Card Port Pinouts
Dual E1/PRI Card Cable Assemblies and Pinouts

Note The tables in this appendix specify pinouts only for the pins used. Pins not listed are not used.

Console and Auxiliary Port Signals and Pinouts

The access server comes with a console and auxiliary cable kit that contains the cable and adapters you need to connect a console (an ASCII terminal or PC running terminal emulation software) or modem to your access server. The console and auxiliary cable kit includes the following items:

RJ-45-to-RJ-45 rollover cable. (See the next section, "Identifying a Rollover Cable," for more information.)
RJ-45-to-DB-9 female DTE adapter (labeled Terminal).
RJ-45-to-DB-25 female DTE adapter (labeled Terminal).
RJ-45-to-DB-25 male DCE adapter (labeled Modem).

For console connections, proceed to the section "Console Port Signals and Pinouts" later in this appendix; for modem connections, proceed to the section "Auxiliary Port Signals and Pinouts" later in this appendix.

Identifying a Rollover Cable

You can identify a rollover cable by comparing the two modular ends of the cable. Holding the cables side-by-side, with the tab at the back, the wire connected to the pin on the outside of the left plug should be the same color as the wire connected to the pin on the outside of the right plug. (See Figure C-1.) If your cable was purchased from Cisco Systems, pin 1 will be white on one connector, and pin 8 will be white on the other (a rollover cable reverses pins 1 and 8, 2 and 7, 3 and 6, and 4 and 5).

Figure C-1: Identifying a Rollover Cable

Console Port Signals and Pinouts

Use the RJ-45-to-RJ-45 rollover cable and RJ-45-to-DB-9 female DTE adapter (labeled Terminal) to connect the console port to a PC running terminal emulation software. Figure C-2 shows how to connect the console port to a PC. Table C-1 lists the pinouts for the asynchronous serial console port, the RJ-45-to-RJ-45 rollover cable, and the RJ-45-to-DB-9 female DTE adapter (labeled Terminal).
