Chapter 3 Installing Cisco uBR7100 Series Universal Broadband Routers
Connecting to the Network
Connecting to the Network
This section describes how to connect the router to your network. The cables required to connect the
router to a network are not provided. For ordering information, contact customer service. For cable
product numbers and port pinouts, see Appendix C, “Cable Specifications”.
The router has integrated LAN Fast Ethernet ports and arrives with the modular port adapter already
installed, unless you order a port adapter separately as a spare. For information on installing port
adapters, see the installation and configuration notes for your port adapter.
Warning
Do not work on the system or connect or disconnect cables during periods of lightning activity.
Statement 1001
Warning
Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF
or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables,
detach the end away from the unit first.
Statement 1026
Connecting Upstream and Downstream Ports
The upstream and downstream ports are connected as follows:
• DS0 RF outputs the downstream after it has been processed by the Cisco uBR7100 series integrated
upconverter. This is an RF signal suitable for output to a combiner.
• DS0 outputs the downstream as an IF signal. This signal must be output into an external
waveconverter before sending it to a combiner.
• US connects the upstream cables to the upstream ports. If an upstream port is not being used, it
should remain unconnected.
Use high-quality RG-59 cabling for both the upstream and downstream ports. RG-6 cable is not
recommended for headend use.
