SYSTEM DESCRIPTION

The 6452A Boradband Translator is a multi-channel translator designed to be used by wireless cabel
operators to provide MMDS/ITFS service without the added expense of a headend. The unit inputs
multichannel superband (222 to 408 MHz) then upconverts and amplifies the signal to RF. The power
capability of the unit varies with the number of channels according to specifications with a peak envelope
power of 6.0 watts.

This manual covers the description, installation, set-up, operation, schematic and interconnect drawings, as
well as other useful technical information.

TECHNICAL MANUAL DESCRIPTION

This manual has been provided to assist with the set-up, operation, and maintenance of the translator. The
System section of the manual offers a brief system description, block diagrams, interconnect, front panel
description, rear panel description, and a specification sheet. If after reviewing this manual, you still have
questions, please contact the ADC Service Company at [phone]. A Customer Service Technician
will be glad to assist you.

INSTALLATION PROCEDURE

UNPACKING

ADC Telecommunications certifies that upon leaving our facility, your equipment was undamaged and in
proper working order. Please inspect all material upon arrival for any sign of damage. The shipping
container should be examined for obvious damage indicative of rough handling. Remove the translator and
all other material from the shipping container and check for damage: dents, large scratches, or broken
connectors etc. Open the translator and remove all packing material from inside the unit and inspect for
damage. Any claim s ag ainst in-transit damage should be directed to the Carrier.

SITE CONSIDERATIONS

Since the 6452A is tray based, it must be mounted in a 19" equipment rack. This cabinet must be housed in
an environmentally controlled cabinet or building. It is also very important to v erify that adequate AC power
is available.

Complete the following for equipm ent installation:

If the unit is supplied with a cabinet, carefully remove the cabinet from the shipping container. If the
translator tray has been shipped separately, the internal shipping material must be removed from inside the
cabinet before the tray is installed. Cut and remove the cable ties or cords which hold the tray harness
breakouts to the tray slides. Carefully remove the foam packing material from around the cables, connectors
and slides. Do
cabinet has been properly positioned, the trays can now be installed.

not

use a knife or other sharp object, as these may cut into the harness wires. Once the

Extend the cabinet mounted slide rails out to their full and locked position. Place the tray with the slides into
the cabinet slide rails until the tray locks into place. Press the side lock tabs on the rails to unlock the tray
and carefully move the tray completely into the rack. Check that the cable breakouts in the rear are not
caught on the tray as the tray is slid into place.

If the trays were shipped mounted in the cabinet, a front and rear shipping bracket must be removed in order
to allow the trays to be pulled out.

If the tray does not slide in and out of the cabinet smoothly, loosen the hardware holding the slides in place.
Move the tray accordingly and tighten the hardware again. Repeat if necessary until the tray slides in and
out freely.

Next, secure the small cable retractors (attached to the main harness) to the back of the tray by sliding them
into the clip located between the AC hook up and the fan on the back of the tray.

Connect the wires to the back of the tray. Each wire is marked with a number corresponding to the location
where it should be connected to the back of the tray.

CABINET NOT SUPPLIED

Two tray slides are provided with the translator. Locate the left slide (without the cable retractor) and mount
the slide to the left side of the cabinet (looking from the rear) using the supplied hardware. Refer to the
Cabinet Mounting Diagram for further detail. C heck that the slide is lev el from front to back.

NOTE:

Install the remaining slide to the right side of the cabinet. Install the long retractor and hinge bracket to the
stationary section of slide using the supplied hardware.

Extend the cabinet mounted slide rails out to their full and locked position. Place the tray with the slides into
the cabinet slide rails until the tray locks into place. Press the side lock tabs on the rails to unlock the tray
and carefully move the tray completely into the rack. Check that the cable breakouts in the rear are not
caught on the tray as the tray is slid into place.

ADJUST TRAY ASSEMBLY.

Check to see that the tray slides freely with no interference from other assemblies. If not, some adjustment
can be made by sliding the tray out, loosening the front or rear mounting bolts of the slide assemblies, and
moving the tray in the direction required for smooth operation. After the adjustment has been made, firmly
tighten the mounting bolts and check the movement again. Repeat if necessary .

Allow a clearance of approximately 5 inches between the point from where the
stationary section is attached to the cabinet slide and the rear cabinet mounting rail
to permit proper operation of the cable retractors.

INSTALL CABLE RETRACTOR ASSEMBLY.

The Cable Retractor Assembly consists of two parts; (A) a cabinet retractor and (B) a tray retractor.

A)

B)

Both retractors work together to avoid pinching the wiring when the tray is moved
in or out.

The cabinet retractor consists of a short aluminum channel hinged to a
mounting bracket that is to be placed on the right side (looking from the
rear) of the cabinet slide assembly. Refer to the Cabinet Mounting
Diagram for further detail.

The tray retractor is a short aluminum
channel hinged to a slide bracket. The
bracket slides down into the retractor
receptacle which is located at the rear of
the tray.
