Safety Guidelines
ALPHA DRAFT - CISCO CONFIDENTIAL
Telephone Wiring Guidelines
Use the following guidelines when working with any equipment that is connected to telephone
wiring or to other network cabling:
• Never install telephone wiring during a lightning storm.
• Never install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
• Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
• Use caution when installing or modifying telephone lines.
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.
Figure8 shows the location of a printed circuit board when it is installed in a network processing
engine, I/O controller, or CiscouBR7200 series modem card metal carrier. Do not touch the printed
circuit board when handling either component.
Figure8 Handling the Cisco uBR7200 Series Wireless Modem Cards—Side View
Although the metal carrier helps to protect the printed circuit boards from ESD, wear a preventive
antistatic strap whenever handling the network processing engine, I/O controller, port adapters, or
wireless modem cards. Ensure that the strap makes good skin contact and connect the strap’s clip to
an unpainted chassis surface to safely channel unwanted ESD voltages to ground.
If no wrist strap is available, ground yourself by touching the metal part of the chassis.
CautionMake sure to tighten the captive installation screws on the network processing engine, the
I/O controller, and the wireless modem cards (use a number2 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.

Removing and Installing a Wireless Modem Card
ALPHA DRAFT - CISCO CONFIDENTIAL
Following are guidelines for preventing ESD damage:
• Always use an ESD 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 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.
CautionPeriodically check the resistance value of the antistatic strap. The measurement should be
within the range of 1 and 10 megohm (Mohm).

(return), and red or white is used for –48V. Make certain the lead color coding you choose for the
DC-input power supply matches lead color coding at the DC power source.
WarningBefore working on equipment that is connected to power lines, remove jewelry (including
rings, necklaces, and watches). metal objects will heat up when connected to power and ground and
can cause serious burns or weld the metal object to the terminals.
WarningBefore performing any of the following procedures, ensure that the power is removed
from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board
that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch
handle of the circuit breaker in the OFF position.
Wiring the DC power consists of attaching the wires of the DC power source to a removable wiring
block, then plugging that block into the connection on the power feed panel. Refer to Figure19 and
Figure20 and follow these steps.
Step1 Ensure that the leads are disconnected from the power source.
WarningThe Illustration shows the DC power supply terminal block. Wire the DC power supply
using the appropriate wire terminations at the wiring end, as illustrated. The proper wiring sequence
is ground to ground, positive to positive (line to +), and negative to negative (neutral to –). Note that
the ground wire should always be connected first and disconnected last.
WarningWhen stranded wiring is required, use approved wiring terminations, such as closed-loop
or spade-type with upturned lugs. These terminations should be the appropriate size for the wires
and should clamp both the insulation and the conductor.
Step2 Ensure that the power switch for both the main and diversity ODU are in the OFF (0)
position. (See Figure18.)

Step3 Using a wire stripper, strip approximately 0.55 in. (14 mm) from the +48V, –48V and
ground leads.
Step4 Insert the stripped ends of the wire in the removable wiring block according to the scheme
in Figure19. Figure19 illustrates the polarity of each connection. The connection on the
left is for the –48VDC wire, the middle connection is for safety ground. The connection
on the right is for the positive return wire.
Figure19 Wiring Connections
Secure the wires using the 1/8 in. blade screwdriver to tighten the screws in the top of the
terminal block.
Step5 Connect the DC input wiring to the DC source.
WarningFor personal safety, the green or green/yellow wire must connect to safety (earth) ground
at both the equipment and supply side of the DC wiring.
Step6 Plug the terminal block into the receptacle on the power feed panel. (See Figure20.)
Figure20 Plugging the Terminal Block into the Receptacle
Warning
After wiring the DC power supply, remove the tape from the circuit breaker switch handle
and reinstate power by moving the handle of the circuit breaker to the ON position.

Cabling the Power Feed Panel
Connecting the Control Cables (from the Modem Card)
Attach the end of the control cable coming from the Control-Main port on the modem card to the
Control-Main/MC port on the power feed panel. If you will be using the diversity option, also attach
the second control cable coming from the Control-Diversity port on the modem card to the
Control-Diversity/MC port on the power feed panel.
Connecting the Control Cables (to the ODU)
Attach a cable with a DB9 connector to the Control-Main/ODU port on the power feed panel. If you
will be using the diversity feature, attach a second cable to the Control-Diversity/ODU port.
Connecting the IF Cables (from the Modem Card)
Connect the cables coming from the Main/PFP port of the modem card to the Main/MC port on the
power feed panel. If you will be using the diversity feature, also connect the cable coming from the
Diversity/PFP port of the modem card to the Diversity/MC port on the power feed panel.
Connecting the IF Cables (to the ODU)
Attach one end of the IF cable to the Main-ODU/Output connector. If you will be using the diversity
feature, attach a second cable to the Diversity-ODU/Output connector.
This completes the procedure for installing and cabling a power feed panel.
Installing an Outdoor Unit
Installing an outdoor unit (ODU) requires the installation of the duplexor assembly prior to
mounting the ODU either on an antenna pole or on a wall.
Installing the Duplexor in the Outdoor Unit
The duplexor acts as a filter for Tx/Rx isolation. The duplexor assembly is shipped as a separate unit
based on the RF channel plan you have selected for your installation.
