Console and Auxiliary Port Considerations

This section discusses important cabling information that must be considered before you
connect the terminals or modems to console and auxiliary ports. The console port and the
auxiliary port are used to provide access to the system either locally or remotely.

Console Port Connections

Each multiport serial router includes an EIA/TIA-232 (RJ-45) console asynchronous serial
port. This port connects to a terminal using an RJ-45 cable and an RJ-45-to-DB-25 adapter
or a PC using the RJ-45 to DB-9 adapter. Depending on the cable and the adapter used, this
port appears as a data terminal equipment (DTE) or data communications equipment
(DCE) device at the end of the cable. To connect to a terminal, use an RJ-45 roll-over cable
with a female DTE connector (labeled Terminal) for connection to the console port. For
detailed information on installing the terminal, see the section "Connecting to the Console
Port" in the chapter "Installing the Cisco Multiport Serial Routers.")
Table B-1 in the appendix "Cisco Multiport Router Cable Specifications" lists the pinout
for the console port. The default parameters for the console port are 9600 baud, 8 data bits,
no parity, and 2 stop bits. The console port does not support hardware flow control or
modem control.

Auxiliary Port Connections

An EIA/TIA-232 (RJ-45) auxiliary asynchronous serial port is included on all multiport
serial routers. This port can connect to a modem for remote maintenance or terminal
services. Use an RJ-45 roll-over cable with a male modem (MMOD) adapter (labeled
Modem) for this connection. For detailed information on connecting devices to the
auxiliary port, see the section "Connecting a Modem to the Auxiliary Port" in the chapter
"Installing the Cisco Multiport Serial Routers." See Table B-1 in the appendix "Cisco
Multiport Router Cable Specifications" for the pinout for the auxiliary port.
