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.

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 6476BBROADBAND BOOSTER PAGE 3
INITIAL TURN ON
Prior to turning on the system, be sure all connections are in the correct place, and
AC power is connected to the back of each tray.
Turn on circuit breaker (CB1) located on the back of each tray.
Place the Broadband Booster Tray in OPERATE mode. The green OPERATE
LED should be on.
The following green LED’s should be on when in OPERATE mode.
