Connecting Route Processor Cables
This section describes how to connect cables to the console, auxiliary, and Ethernet ports on the RP. The
console and auxiliary ports are both asynchronous serial ports; any devices connected to these ports must be
capable of asynchronous transmission. Most modems are asynchronous devices.
The following figure shows an example of an RP with data terminal and modem connections called out.

The ports labeled Ethernet, Console, and AUX are safety extra-low voltage (SELV) circuits. SELV circuits
should only be connected to other SELV circuits.
Caution
RP cables are not available from Cisco, but they are available from external commercial cable vendors.
Note
To comply with the intra-building lightning surge requirements of Telecordia GR-1089-CORE, Issue 6, you
must use a shielded cable when connecting to the Ethernet ports. The shielded cable is terminated by shielded
connectors on both ends, with the cable shield material tied to both connectors.
Note
Connecting to the RP Console Port
The system console port on the RP is an RJ-45 receptacle for connecting a data terminal to perform the initial
configuration of the router. Depending on the cabling pinout on the terminal server end, the console port will
