Wireless Modem Card and Subsystem Overview
The Cisco high-speed point-to-point broadband fixed wireless system provides a fixed, dedicated
wireless link from one site to another. This link delivers full-duplex data in the licensed MMDS band
(2.500 to 2.690 GHz), or unlicensed U-NII band (5.725 to 5.825 GHz).
The broadband fixed wireless system consists of a Cisco uBR7200 series universal broadband router
(Cisco uBR7246 or Cisco uBR7223) and one or more wireless modem cards (see Figure 1), each
with a power feed panel (see Figure 2), and one or two wireless transverters (see Figure 3). (The
diversity option, which minimizes the effects of fading, uses two wireless transverters, one for each
of two antennas.)

Electrical Equipment Guidelines
Follow these basic guidelines when working with any electrical equipment:
•
Before beginning any procedures requiring access to the chassis interior, locate the emergency
power-off switch for the room in which you are working.
•
•
•
•
Disconnect all power and external cables before moving a chassis.
•
•
Never install equipment that appears damaged.
Do not work alone if potentially hazardous conditions exist.
Never assume that power has been disconnected from a circuit; always check.
Do not perform any action that creates a potential hazard to people or makes the equipment
unsafe.
Carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damages equipment and impairs electrical circuitry. ESD occurs when
printed circuit boards are improperly handled and results in complete or intermittent failures
The network processing engine, I/O controller, port adapters, and wireless modem cards consist of
a printed circuit board that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding,
connectors, and a handle are integral components of the carrier. Handle the network processing
engine, I/O controller, port adapters, and wireless modem cards by their carrier edges and handles;
never touch the printed circuit board when handling either component.

an unpainted chassis surface to safely channel unwanted ESD voltages.
If no wrist strap is available, ground yourself by touching the metal part of the chassis.
Caution Be sure to tighten the captive installation screws on the network processing engine, the
I/O controller, and the wireless modem cards (use a number 2 Phillips screwdriver). These screws
prevent accidental removal, provide proper grounding for the router, and help to ensure that the
network processing engine, I/O controller, and modem cards are properly seated in the router
midplane.
Following are guidelines for preventing ESD damage:
•
Always use an ESD-preventive wrist strap or ankle strap when installing or replacing the network
processing engine, I/O controller, port adapters, or modem cards. Ensure that the ESD-preventive
strap makes contact with your skin.
•
Handle the network processing engine, I/O controller, port adapters, or modem cards by their
metal carrier edges and handles only; avoid touching the printed circuit board components or any
connector pins.
•
When removing the network processing engine, I/O controller, port adapters, or wireless modem
cards, place them on an antistatic surface with the printed circuit board components facing
upward, or in a static shielding bag. If you are returning an I/O controller, network processing
engine, port adapter, or modem card to the factory, immediately place it in a static shielding bag.
Caution Periodically check the resistance value of the antistatic strap. The measurement should be
within the range of 1 to 10 megohms (Mohm).
Warning Do not work on the system or connect or disconnect cables during periods of lightning
activity.
