Connecting Port Adapter Cables

Connecting Port Adapter Cables
The instructions for connecting the cables for the port adapter installed in the Cisco 7301 router are
contained in the respective configuration notes for each port adapter. For example, if you are connecting
the optical fiber cables for the PA-POS-OC3 port adapter, refer to the configuration note PA-POS-OC3
Packet OC-3 Port Adapter Installation and Configuration at
http://www.cisco.com/univercd/cc/td/doc/product/core/7206/port_adp/sonet_pa/paposoc3/index.htm.
Port adapter documents are also available on the Documentation CD-ROM.

Connecting I/O Cables

This section contains connection equipment information for the Gigabit Ethernet, console, and auxiliary
ports.
The ports labeled "Ethernet," "10BaseT," "Token Ring," "Console," and "AUX" are safety extra-low

voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Because the
BRI circuits are treated like telephone-network voltage, avoid connecting the SELV circuit to the
telephone network voltage (TNV) circuits. Statement 22

Connecting Console and Auxiliary Port Cables

The console cable kit product number is ACS-2500ASYN.
Note
The Cisco 7301 router has a DCE-mode console port for connecting a console terminal, and a DTE-mode
auxiliary port for connecting a modem or other DCE device (such as a CSU/DSU or other router) to your
router.
Both the console and the auxiliary ports are asynchronous serial ports; any devices connected to these
Note
ports must be capable of asynchronous transmission. (Asynchronous is the most common type of serial
device; for example, most modems are asynchronous devices.)
The Cisco 7301 router uses RJ-45 ports for both the auxiliary port and console port.
Before connecting a terminal to the console port, configure the terminal to match the router console port
as follows: 9600 baud, 8 data bits, no parity, 1 stop bits (9600 8N1). After you establish normal router
operation, you can disconnect the terminal.
For console and auxiliary port pinouts for the RJ-45 connector, see
Specifications."
