Chapter 3 Installing a Cisco 7200 VXR Router

Connecting I/O Controller, NPE-G1, or NPE-G2 Cables

Note Both the console and the auxiliary ports are asynchronous serial ports; any devices connected to these ports must be capable of asynchronous transmission. (Asynchronous is the most common type of serial device; for example, most modems are asynchronous devices.)

The I/O controller uses two types of physical media for console port and auxiliary port connections. Table 3-13describes the I/O controller console and auxiliary port media type for each model.

The NPE-G1 and NPE-G2 use RJ-45 media for console port and auxiliary port connections. See Table 3-18for console port pinout information and Table 3-19for auxiliary port pinout information.

Table 3-13	Console and Auxiliary Port Physical Media
Model		Console Port	Auxiliary Port
C7200-I/O-GE+E		RJ-45 port	RJ-45 port
C7200-I/O-2FE/E		RJ-45 port	RJ-45 port
C7200-I/O-FE		DB-25 port	DB-25 connector
C7200-I/O		DB-25 port	DB-25 connector
C7200-I/O-FE-MII		DB-25 port	DB-25 connector

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, 2 stop bits (9600 8N2). After you establish normal router operation, you can disconnect the terminal.

DB-25 Port Cabling and Pinouts

The DB-25 ports and connectors conform to the EIA/TIA-232 serial data transfer standard for communications between DTE and DCE equipment. Figure 3-28shows console and auxiliary port connections for DB-25 physical media.
