Console Port Cabling Specifications and Pinouts
The console port, which is located on the front panel of the supervisor engine or route switch processor,
provides access to the Cisco 7600 router. The following sections provide information about the console
port cabling specifications and the port’s signals and pinouts.
• Console Port Cabling Specifications, page B-10

Console Port Cabling Specifications
Table B-9 lists the maximum transmission distances for console port cables. See the “Console Port
Signals and Pinouts” section on page B-11 for console port and cable pinout information.
The accessories kit that is shipped with your router contains the necessary cable and adapters to connect
a terminal or modem to the front-panel console port.
