6470B Series Broadband MMDS Booster 20 W - 1000 W

6470 SERIES

MMDS

Overview

Wireless cable systems may have shadowed areas that cannot be serviced by the

main transmitter site. Booster systems offer an economical solution to increase your

subscriber base and expand your coverage area.

Broadband Booster

The 6470B series are rack mounted broadband amplifiers that provide multichannel

retransmission of 2076-2686 MHz signals, digital or analog. Operators can choose

from seven models which provide from 20 to 1000 watts of peak power.

256 QAM or 16 VSB Compatible

6470B boosters are compatible with any level of QAM modulation up to and

including M=256 and any level of VSB modulation up to and including M=16.

These units are also compatible with other digital modulation schemes, both single

carrier and OFDM.

Excellent BER Performance

Feedforward equalization techniques are employed to meet performance

specifications while minimizing power consumption.

Anytime, Anywhere Communication and Backup

With the Remote Monitoring System, operators have real time remote and local

control of the booster system and site. Graphic user interfaces operate on the

Windows operating system.

INSTALLATION PROCEDURE

UNPACKING

Please inspect all material thoroughly upon arrival. Axcera certifies that upon leaving
our facility the equipment was undamaged and in proper working order. The shipping
container should be inspected for obvious damage indicative of rough handling.

Remove the unit(s) from the shipping container and inspect for damage. Check for
dents, and scratches, or a broken switch, meter or connector. Remove the top cover of
the unit and again inspect for shipping damage. Extract all packing material from
inside and around the unit. Check for loose hardware and connectors, retighten if
needed. Any claims against in-transit damage should be directed to the carrier. Save
all packing material in case it is needed in the future.

INSTALLATION OF TRAY(S)

Units are shipped with chassis slides mounted to the each side. Included in the

Installation Material Kit are two cabinet mount slide assemblies that will be
mounted in the rack. Install the Tray slides into the cabinet. Refer to the "Cabinet
Mounting Instructions Slides Drawing" which follows, for detailed instructions.

Slide the unit into the cabinet. If it does not slide in and out smoothly, some

adjustment is necessary. Pull out the unit (only enough for clearance) and loosen
the hardware holding the cable slides to the cabinet. Move the front of the Tray up
or down or side to side to remove the rubbing. Retighten the hardware after the
adjustment is complete.

Also included with the unit is a cable retractor assembly which consists of two

parts, a cabinet mount retractor and a tray mount retractor.

The cabinet mount retractor has a long aluminum channel hinged to a

mounting piece with two bolts. This is mounted to the rear of the left hand,
facing the front of the unit, cabinet mount slide assembly.

The retractor is a short aluminum channel hinged to a slide mount. This piece

slides into a receptacle mounted to the rear panel of the unit.

These cable retractors work together to move the wire harness and coaxial cables in
and out with the movement of the unit to avoid pinched wires.

After the units(s) are physically in place, the process of interfacing them into the

system begins by making connections to the back of the units.

SYSTEM 6476B BROADBAND BOOSTER PAGE 2

CABINET MOUNTING INSTRUCTIONS FOR SLIDES DRAWING

CONNECTIONS

Once all equipment is in place, making connection to the back of the tray (s) is a
relatively simple process. Each wire is clearly marked with a number corresponding to
the tray where it connects.

NUMBERING

The numbering system used on wires that connect to the back of the trays is as
follows:

FIRST NUMBER - Channel designator

SECOND NUMBER - Connector on back of tray

EXAMPLE: A wire marked 2 10 would go to channel 2 in the group,
connector J10

Finally, verify that AC power (J1) is connected to each unit. Once this is complete,
proceed to the initial turn on procedures.

NOTE: All Axcera products are designed for operation with either 115VAC or
208/240VAC 50/60Hz input. Systems are shipped from the factory properly configured
for the standard of the country of destination.

OPERATION 6476B BROADBAND BOOSTER PAGE 3

MAINTENANCE 6476B BROADBAND BOOSTER

MAINTENANCE

PROPER CARE OF THE SYSTEM

This product is designed with components that require no periodic maintenance except for
cleaning and record keeping.

The amount of cleaning necessary depends greatly on the conditions in the transmitter room.
While the electronics have been designed to function well even if covered with dust, heavy
buildups of dirt and insects will impede the effectiveness of the cooling and lead to shutdown
or premature failure.

When it is apparent that the front panel is becoming dust covered, the top cover should be
opened and the accumulated foreign material removed. A small, soft brush used in
conjunction with a plastic wand-like attachment on a small vacuum cleaner is an excellent way
to suction the dirt out. Alcohol and other cleaning agents should not be used unless you can
be certain that the solvents will not damage components or markings on the transmitter and
boards. Water based cleaners can be used, if only a small amount of moisture is used. The
fans and heatsinks should be cleaned carefully.

Occasionally check that all RF connections are secure, but be careful not to overtighten.

WARNING!!!

DO NOT ATTEMPT TO REPAIR OR TROUBLESHOOT THIS EQUIPMENT
UNLESS YOU ARE FAMILIAR WITH ITS OPERATION AND EXPERIENCED IN
SERVICING HIGH VOLTAGE EQUIPMENT. LETHAL VOLTAGES ARE PRESENT
WHEN POWER IS APPLIED TO THIS SYSTEM. IF POSSIBLE, TURN OFF
POWER BEFORE MAKING ADJUSTMENTS TO THE SYSTEM.

EMERGENCY FIRST AID INSTRUCTIONS

Personnel engaged in the installation, operation, or maintenance of this equipment are urged to become
familiar with the following rules both in theory and practice. It is the duty of all operating personnel to be
prepared to give adequate Emergency First Aid and thereby prevent avoidable loss of life.

1. Find out if the person is
breathing.

You must find out if the person
has stopped breathing. If you
think he is not breathing, place
him flat on his back. Put your ear
close to his mouth and look at his
chest. If he is breathing you can
feel the air on your cheek. You
can see his chest move up and
down. If you do not feel the air
or see the chest move, he is not
breathing.

RESCUE BREATHING

2. If he is not breathing, open
the airway by tilting his head
backwards.

Lift up his neck with one hand
and push down on his forehead
with the other. This opens the
airway. Sometimes doing this will
let the person breathe again by
himself. If he does not start
breathing, begin rescue
breathing.

BURNS

SKIN REDDENED: Apply ice cold water to burned
area to prevent burn from going deeper into skin
tissue. Cover area with clean sheet or cloth to keep
away air. Consult a physician.

SKIN BLISTERED OR FLESH CHARRED: Apply ice
cold water to burned area to prevent burn from
going deeper into skin tissue.

3. If he is still not breathing,
begin rescue breathing.

-Keep his head tilted backward.
Pinch nose shut.

-Put your mouth tightly over his
mouth.

-Blow into his mouth once every
five seconds

-DO NOT stop rescue breathing
until help comes.

LOOSEN CLOTHING - KEEP
WARM

Do this when the victim is
breathing by himself or help is
available. Keep him as quiet as
possible and from becoming
chilled. Otherwise treat him for
shock.

Cover area with clean sheet or cloth to keep away
air. Treat victim for shock and take to hospital.

EXTENSIVE BURN - SKIN BROKEN: Cover area with
clean sheet or cloth to keep away air. Treat victim
for shock and take to hospital.
