Chapter 2 Preparing for Router Installation

Auxiliary Port Connections

The router has an EIA/TIA-232 asynchronous serial auxiliary port (RJ-45) that supports flow control.
Depending on the cable and the adapter used, this port will appear as a DTE or DCE device at the end
of the cable.
For connection to a modem, your router is provided with an RJ-45-to-DB-9 cable and a DB-9-to-DB-25
adapter.
For detailed information about connecting devices to the auxiliary port, see the
Auxiliary Port" section on page
For cable and port pinouts, refer to the
Cisco.com.

Preparing to Connect to a Network

When setting up your router, consider distance limitations and potential electromagnetic interference
(EMI) as defined by the applicable local and international regulations.
The following sections describe network connection considerations for several types of network
interfaces:
