Chapter 3 Installing the Router
Connecting the PRP to an Ethernet Network
Ensure that a console terminal is connected to the RP console port and turned on, 
or that you have a remote login to the router from another device through a telnet 
session.
Connecting the PRP to an Ethernet Network
The PRP includes two 10/100 Mbps Ethernet ports, each using an 8-pin RJ-45 
receptacle for either IEEE 802.3 10BASE-T (10 Mbps) or IEEE 802.3u 
100BASE-TX (100 Mbps) connections. The transmission speed of the Ethernet 
ports is auto-sensing by default and is user configurable.
To connect cables to the PRP Ethernet interfaces (ports labeled ETH0 and ETH1), 
attach the Category 5 UTP cable directly to a RJ-45 receptacle on the PRP. 
Note
The Ethernet interfaces on the PRP are end-station devices, not repeaters; 
therefore, you must connect an Ethernet interface to a repeater or hub.
RJ-45 cables are not available from Cisco Systems, but are available from outside 
commercial cable vendors. 
Note
Only connect cables that comply with EIA/TIA-568 standards. See
and
for cable recommendations and specifications.
Note
To comply with Telcordia GR-1089 NEBS standard for electromagnetic 
compatibility and safety, connect all console, auxiliary, and Ethernet interfaces 
only to intrabuilding or non-exposed wiring or cabling. The intrabuilding cable 
must be shielded and the shield must be grounded at both ends.
Caution
The Ethernet ports are primarily used as a Telnet port into the Cisco XR 12000 
Series Router, and for booting or accessing Cisco IOS XR software images over 
a network to which an Ethernet port is directly connected. Cisco Express
