Network Cabling Specifications

The following sections describe the cables and thee specifications required to install Cisco 1100 Series ISRs:

Console Port Connections

The Cisco 1100 Terminal Gateway Routers has EIA/TIA-232 asynchronous (RJ-45) and ASYNC ports. The
console port does not have any hardware flow control.

EIA/TIA-232

Depending on the cable and the adapter used, this port appears as a DTE or DCE device at the end of the
cable. Only one port can be used at the same time.
The default parameters for the console port are 9600 baud, 8 data bits, 1 stop bit, and no parity. The console
portdoes not support hardware flow control. For detailed information about installing a console terminal, see
the Connecting to a Console Terminal or Modem section.
For cable and port pinouts, see the Cisco Modular Access Router Cable Specifications document located on
Cisco.com.

Console Port Considerations

The router includes an asynchronous serial console port. The console ports provide access to the router using
a console terminal connected to the console port. This section discusses important cabling information to
consider before connecting the router to a console terminal or modem.
Console terminals send data at speeds slower than modems do; therefore, the console port is ideally suited
for use with console terminals.

Preparing for Network Connections

When setting up your router, consider distance limitations and potential electromagnetic interference (EMI)
as defined by the applicable local and international regulations.

by itself, if possible. Power off other equipment in the rack (and in adjacent racks) to allow the router
under test a maximum of cooling air and clean power.
