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.

Caution To 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.

Note Hardware 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=).

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.

Note On the Cisco uBR7111E and Cisco uBR7114E routers, the DS0 connector is automatically muted when

the DS0 RF port is enabled.

Chapter 1 Product Overview

Note Only one downstream connector should be connected and used for data traffic on the network at any one

time. On the Cisco uBR7111 and Cisco uBR7114 routers, the second downstream connector, however, can be used for local monitoring purposes.

The Cisco uBR7111 and Cisco uBR7111E routers support one upstream port, and the Cisco uBR7114 and Cisco uBR7114E routers support four upstream ports.

Flash Disks

The flash disk is the default memory device that ships with your Cisco uBR7100 series router. Cisco uBR7100 series routers support two installed PCMCIA flash disks that contain the default Cisco IOS software image. Flash disks can be installed in slot 0 and slot 1 of the PCMCIA card slots located at the back of the router. Slot 0 is the top slot and slot 1 is the bottom slot.

To ensure proper electromagnetic compatibility (EMC), the PCMCIA card slot has a cover that is secured with a captive screw.

Tip The flash disk slots are physically identified as slot 0 and slot 1, but they are addressed as disk0 and

disk1, respectively, when accessing the flash disks with Cisco IOS commands.

For procedures that explain the installation and use of the flash disk, see the “Flash Memory Card Usage”

section on page 6-5. Also see the Using the Flash Disk document that accompanies every flash disk

shipped from the factory.

Table 1- 2 lists the flash disk memory options and their product numbers.
