THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL
STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT
WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.
THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT

OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.
The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required
to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not
installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to
comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable
protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital
devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television
communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its
peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
• Move the equipment farther away from the television or radio.
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits
controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

To ensure that all service requests are reported in a standard format, Cisco has established severity
definitions.
Severity 1 (S1)—Your network is “down,” or there is a critical impact to your business operations. You
and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your
business operation are negatively affected by inadequate performance of Cisco products. You and Cisco
will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations
remain functional. You and Cisco will commit resources during normal business hours to restore service
to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or
configuration. There is little or no effect on your business operations.

routers and contains the following sections that describe router hardware, major components, and
functions of hardware-related features:
• Product Description, page 1-1
• Fixed Interface Units, page 1-6
• Field-Replaceable Units, page 1-7
• Functional Overview, page 1-11
NoteUnless otherwise indicated, the term Cisco uBR7100 series in this manual refers to all models of the
Cisco uBR7100 series universal broadband router, including the Cisco uBR7111, Cisco uBR7111E,
Cisco uBR7114, and Cisco uBR7114E routers.
Product Description
The Cisco uBR7100 series universal broadband router is a cable modem termination system (CMTS)
that provides Internet, local area network (LAN), and wide area network (WAN) access for cable
modems and set-top boxes (STBs) over a coaxial cable connection. The router enables high-speed data
services to be packaged similar to basic cable television service or video programming.
The Cisco uBR7100 series routers support two-way data and digitized voice connectivity over a
bidirectional cable television and IP backbone network, using one of the following two standards:
• The Cisco uBR7111 and Cisco uBR7114 support the Data-over-Cable Service Interface
Specifications (DOCSIS)—DOCSIS 1.0 and DOCSIS 1.1. DOCSIS supports the 6 MHz North

All Cisco uBR7100 series routers have one power supply with one AC-input power receptacle. A power
cable connects the AC-input power supply to the site AC power source. The router’s main power switch
is located next to the AC-input power receptacle. Separate power cords are available, depending on the
country of operation.
On the side of each chassis are two chassis ground receptacles—choose the most convenient set for a
chassis ground connection for a two-hole grounding lug, and the other set can provide a mounting
location for the cable management bracket. On the back of the chassis, there is a receptacle for
electrostatic discharge (ESD) equipment.
Four internal fans draw cooling air into the chassis (back to front) and across internal components to
maintain an acceptable operating temperature. There are four environmental sensors for monitoring the
cooling air as it leaves the chassis. For more information on environmental monitoring, see the
“Environmental Monitoring and Reporting Functions” section on page 6-2.
CautionTo ensure the proper flow of cooling air across the internal components, a port adapter must be installed
in the port adapter slot. If no port adapter is installed, install a blank port adapter (the product number
is MAS-7100-PABLANK=). Slot 5 has a blank face plate. For proper airflow, make sure that a blank
faceplate is always installed in slot 5. (The product number is SM-BLANK=).
OL-5916-01
The modular port adapter slides into the chassis slot and connects directly to the router; there are no
internal cables to connect.
The port adapter, fixed cable interface, and fixed LAN interface connect to two peripheral component
interconnect (PCI) buses on the router’s backplane that provide a path to packet I/O memory and the
system processor. For more information, see the “Peripheral Component Interconnect Buses” section on
page 1-14.
Cisco uBR7100 series routers can be installed on a tabletop or in an equipment rack. Rubber feet for
tabletop installation are included in the accessory kit that shipped with your router.
A rack-mount and cable-management kit is also standard equipment included with all Cisco uBR7100
series routers when they are shipped from the factory. The kit provides the hardware needed to mount
the router in a standard 19-inch, four-post or telco-type equipment rack. The rack-mount kit also
provides the hardware necessary to manage the interface cables attached to the router.
NoteHardware to install the Cisco uBR7100 series in a 23-inch or 24-inch rack can also be ordered separately
(the order number is ACS-7100-RMK=).

Fixed Interface Units
The Cisco uBR7100 series universal broadband router contains the following fixed interfaces:
• Ethernet/Fast Ethernet LAN Interface, page 1-6
• RF Cable Interface, page 1-6
Ethernet/Fast Ethernet LAN Interface
The Cisco uBR7100 series contains a fixed LAN Ethernet/Fast Ethernet autosensing interface with two
separately routable 100BASE-TX ports. Both ports support full-duplex and half-duplex operation, and
automatically determine whether the attached network is a 10-Mbps 10BASE-T Ethernet or a 100-Mbps,
100BASE-TX Fast Ethernet network. Each port uses an RJ-45 connector with Category 5 unshielded
twisted-pair (UTP) wiring.
Chapter 1 Product Overview
RF Cable Interface
The Cisco uBR7100 series router includes a fixed cable interface card that provides one downstream port
and from one to four upstream ports, depending on the model.
On the Cisco uBR7111 and Cisco uBR7114 routers, the cable interface supports the North American
DOCSIS channel plan, with a 6 MHz National Television Systems Committee (NTSC) channel width,
with a 5 to 42 MHz upstream frequency range. The downstream supports the 54 to 858 MHz frequency
range with 64 QAM and 256 QAM data rates, while the upstream supports QPSK and 16 QAM data
rates.
On the Cisco uBR7111E and Cisco uBR7114E routers, the cable interface supports the EuroDOCSIS
channel plan, with an 8 MHz pulse amplitude modulation (PAM) and SECAM channel width, with a
5 to 65 MHz upstream frequency range. The downstream supports the 54 to 858 MHz frequency range
with 64 QAM and 256 QAM data rates, while the upstream supports QPSK and 16 QAM data rates.
Two downstream connectors are provided:
• DS0 RF—Outputs the downstream after it has been processed by the router’s integrated upconverter,
thereby creating an RF signal suitable for connection to a combiner and transmission on the coaxial
cable network.
• DS0—Outputs the downstream as an IF signal, requiring an external upconverter to process the
signal for output on the coaxial cable network.
NoteOn the Cisco uBR7111E and Cisco uBR7114E routers, the DS0 connector is automatically muted when
the DS0 RF port is enabled.
