Chapter 2 Preparing to Install the Router
Preparing to Connect to a Network
To connect the router to an ASCII terminal, use an RJ-45 rollover cable and an RJ-45-to-DB-25 female adapter (not provided).
The default parameters for the console port are 9600 baud, 8 data bits, no parity, and 1 stop bit. The console port does not support hardware flow control. For detailed information about installing a console terminal, refer to the “Connecting to a Console Terminal or Modem” section on page 3-20.
For cable and port pinouts, refer to the Cisco Modular Access Router Cable Specifications document online or on the Documentation CD-ROM.
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 appears 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-25 adapter cable.
For detailed information about connecting devices to the auxiliary port, refer to the “Connecting to a Console Terminal or Modem” section on page 3-20.
For cable and port pinouts, refer to the Cisco Modular Access Router Cable Specifications document online or on the Documentation CD-ROM.
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.
Network connection considerations are provided for several types of network interfaces and are described in the following sections:
•Ethernet Connections, page 2-9
•Token Ring Connections, page 2-9
•Serial Connections, page 2-10
•ISDN BRI Connections, page 2-12
•56-K/Switched-56-kbps DSU/CSU Connections, page 2-13
Refer to the following online documents for more information about network connections and interfaces:
•Cisco Network Modules Hardware Installation Guide
•Cisco Interface Cards Installation Guide
•Cisco Modular Access Router Cable Specifications
Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. Statement 1021
