Cabling Specifications


This appendix provides the following cabling and pinout information for the Cisco AS5400 and Cisco AS5400HPX universal gateways:

Console and Auxiliary Port Cables and Pinouts

Ethernet Port Pinouts

BITS Cable and Port Pinouts

Alarm Port Pinouts

Bantam Jack Port Pinouts


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



Note Unless specifically noted, all references to the Cisco AS5400 also apply to the Cisco AS5400HPX.


Console and Auxiliary Port Cables and Pinouts

The universal gateway arrives with a console and auxiliary cable kit, which contains the cable and adapters you need to connect a console (an ASCII terminal or PC running terminal emulation software) or modem to your universal gateway. The console and auxiliary cable kit includes:

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 Cables and Pinouts" on page C-2. For modem connections, proceed to the section "Auxiliary Port Signals and Pinouts" on page C-4.

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 connector (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 Cables 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).

Use the RJ-45-to-RJ-45 rollover cable and RJ-45-to-DB-25 female DTE adapter (labeled TERMINAL) to connect the console port to a terminal. Figure C-3 shows how to connect the console port to a terminal. Table C-2 lists the pinouts for the asynchronous serial console port, the RJ-45-to-RJ-45 rollover cable, and the RJ-45-to-DB-25 female DTE adapter (labeled TERMINAL).

Auxiliary Port Signals and Pinouts

Use the RJ-45-to-RJ-45 rollover cable and RJ-45-to-DB-25 male DCE adapter (labeled MODEM) to connect the auxiliary port to a modem. Figure C-4 shows how to connect the auxiliary port to a modem. Table C-3 lists the pinouts for the asynchronous serial auxiliary port, the RJ-45-to-RJ-45 rollover cable, and the RJ-45-to-DB-25 male DCE adapter (labeled MODEM).
