The console and auxiliary ports are asynchronous serial ports; any devices
Note
connected to these ports must be capable of asynchronous transmission. (Asynchronous is
the most common type of serial device; for example, most modems are asynchronous
devices.)
In order to maintain Class B EMI compliance, shielded cables must be used on the
Note
console and auxiliary ports of the GRP= and GRP-B=. An updated version of the GRP-B=
board (Rev. F0) is available. This version does not require shielded cables for Class B
compliance.
Before connecting a terminal to the console port, check your terminal's documentation to
determine the baud rate of the terminal you plan to use. The baud rate of the terminal must
match the default rate (9600 baud). Set up the terminal as follows: 9600 baud, 8 data bits,
no parity, 2 stop bits (9600 8N2). You need an EIA/TIA-232 DCE console cable to connect
the terminal to the console port. Cisco Systems does not provide console and auxiliary port
cables; cables are available from commercial sources.
