Document Cautions and Notes
Two types of messages, identified below, appear in the text:
CAUTION!
Caution text indicates operations or steps that could cause personal injury, induce a
safety problem in a managed device, destroy or corrupt information, or interrupt or stop
services.
NOTE:
Note text contains information about special circumstances.
General Safety Precautions
CAUTION!
Wet conditions increase the potential for receiving an electrical shock when installing or
using electrically powered equipment. To prevent electrical shock, never install or use
electrical equipment in a wet location or during a lightning storm.
CAUTION!
This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation can
seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do
not look directly into the optical transceiver of any digital unit or exposure to laser
radiation may result. Use an optical power meter to verify active fibers. Immediately
place a protective cap or hood over any radiating transceiver or optical fiber connector to
avoid the potential of dangerous amounts of radiation exposure. This practice also
prevents dirt particles from entering the adapter or connector.
CAUTION!
This system is a RF Transmitter and continuously emits RF energy. Maintain a minimum
clearance of three feet (91.4 cm) from the antenna while the system is operating.
Wherever possible, shut down the RAN before servicing the antenna.

Preface
Standards Certification
FCC: This equipment complies with the applicable sections of Title 47 CFR, Part 22
(800 MHz Cellular), Part 24 (1900 MHz - PCS), Part 90 (800/900 - SMR), and Part
27 (700 MHz, 2100 MHz - AWS).
IC: This equipment complies with the applicable sections of RSS-131 (800/900 –
SMR), RSS-132 (800 - Cellular), and RSS-133 (1900 – PCS). The term “IC:” before
the radio certification number only signifies that Industry Canada Technical
Specifications were met.
The Manufacturer's rated output power of this equipment is for single carrier
operation. For situations when multiple carrier signals are present, the rating
would have to be reduced by 3.5 dB, especially where the output signal is
re-radiated and can cause interference to adjacent band users. This power
reduction is to be by means of input power or gain reduction and not by an
attenuator at the output of the device.
NOTE:
The U.S. Federal Communications Commission (FCC) has developed guidelines for
evaluation of human exposure to RF emissions. The guidelines incorporate limits for
Maximum Permissible Exposure (MPE) for power density of transmitter operating at
frequencies between 300 kHz and 100 GHz. Limits have been set for portable, mobile, and
fixed equipment. ADC products fall in the category of fixed equipment; products intended
to be permanently secured and exposures are evaluated for distances greater than 20cm
(7-7/8”). Portable devices fall into exposures of less than 20cm, where SAR evaluations
are used.
Antenna gain is restricted to 1.5 W ERP (2.49 W EIRP) in order to satisfy RF exposure
compliance requirements. If higher than 1.5 W ERP, routine MPE evaluation is needed.
The antennas should be installed to provide at least 20cm from all persons to satisfy MPE
requirements of FCC Part 2, 2.1091.
UL/CUL: This will be installed in a restricted access location. This equipment
complies, per UL and CUL 50, Standard for Enclosures for Electrical Equipment.
UL/CUL: This equipment complies with UL and CUL 60950-1 Standard for Safety
for Information Technology Equipment, including Electrical Business Equipment.
UL: This equipment is UL Plenum rated under UL 2043.
CAUTION!
Modifications not expressly approved by the party responsible for compliance could void
the user's authority to operate the equipment.

Product Overview
PRODUCT OVERVIEW
InterReach Spectrum supports up to eight frequency bands in a single system.
Each antenna location supports those bands in modular, group pairings. Each
location includes a Main Remote Access Unit (MRAU), which can power up to three
additional Secondary Remote Access Units (SRAUs). An MRAU supports two
frequency bands, and each SRAU can support up to two frequency bands, for a
total of up to eight frequency bands. MRAUs and SRAUs are grouped logically,
based on common service provider groupings and include, as an example:
• 850/1900
• 700/700 MIMO
• 800/900 SMR
• 1900/AWS.
To add more frequency bands, you connect an SRAU to the existing MRAU.
Figure 1 illustrates how RF and IF signals are sent between Spectrum units and
modules.

INSTALL THE RAUS AND ANTENNAS
Follow the steps in the order provided to install the RAUs and antennas.
Mount the RAUs and Antennas
CAUTION!
Install RAUs in indoor locations only. Do not connect an antenna installed in an outdoor
location to a RAU, unless it is in an approved AOC weatherproof NEMA4 housing.
CAUTION!
Attach all RAUs securely to a stationary object (that is, a wall, pole, or ceiling brackets).
To mount a RAU securely to a wall, ceiling bracket, or pole, use #6 diameter fasteners in
the four slotted mounting holes.
CAUTION!
Do the following to maintain proper ventilation:
•
Keep at least 76 mm (3-inch) clearance around the RAU.
•
Do not stack RAUs on top of each other.
•
Always mount the RAU with the solid face (containing the mounting holes) against the
mounting surface.

ADCP-77-168 • Issue 2 • 07/2011
Install the RAUs and Antennas
NOTE:
RAUs are suitable for use in environmental air space in accordance with Section
300-22(c) of the National Electrical Code, and Sections 2-128, 12-010(3) and 12-100 of
the Canadian Electrical Code, Part 1, CSA C22.1.
NOTE:
You can place the RAU, without its fastening hardware, on a flat surface, such as a shelf,
desk, cabinet, or any other horizontal surface that allows stable placement, with the
mounting base facing down to the mounting surface.
CAUTION!
If installing the RAU on a flat surface, the surface must be able to hold a minimum
7-pound load securely.
1 Mount all MRAU and SRAUs in the locations marked on the floor plans.
2 Install the passive antennas according to the manufacturer’s installation
instructions.
NOTE:
It is common practice to install passive antennas below the ceiling. If you install a
passive antenna above the ceiling, when estimating the antenna coverage area, account
for additional loss due to the ceiling material.
3 Connect a passive multi-band antenna to the N connector on each RAU using
coaxial cable with the least amount of loss possible. (See “Appendix C: Omni
Antenna” on page 21 for information on the Omni Antenna ports.)
CAUTION!
Firmly hand-tighten the N connector. DO NOT over-tighten the connector.

Connect the IFEU to the MRAU
NOTE:
The IFEU should be powered up before starting this procedure; see the InterReach
Spectrum Expansion Module Group Installation Guide (ADCP-77-167).
4 Follow these rules for the CATV cables when connecting the IFEU to the MRAU:
• The FWD and REV cables should be close to the same length.
• The FWD and REV cables should be the same cable type (both RG6 or both
RG11).
• A pair of CATV cables connects each MRAU to the IFEU. The IFEU REV
Module IF IN port and the IFEU FWD Module IF OUT port must match. For
example, if IFEU REV Module IF IN Port 3 is used, use IFEU FWD Module IF
OUT Port 3.
• Refer to “Appendix B: 75-Ohm CATV Cable” on page 16 for information on
maximum RG-6 or RG-11 CATV cable lengths.
5 Test the cable termination for each CATV cable before installing it.
6 Connect F connector CATV cables on the IFEU and MRAU, in the order given
below.
If the LEDs do not perform as described in this procedure, refer to “MRAU LEDs”
on page 6.
a Connect a CATV cable from one of the IFEU FWD Module IF OUT connectors
(1 - 8) to the MRAU FWD IF IN connector.
b Confirm that the MRAU FWD IF IN LED is yellow, which indicates a correct
physical connection.
Connect a CATV cable from the IFEU REV Module IF IN connector (1 - 8) to
the MRAU REV IF OUT connector, making sure that you pair the port used
to the same port number selected in Step 6a.

Appendix B: 75-Ohm CATV Cable
APPENDIX B: 75-OHM CATV CABLE
The 75-Ohm CATV Cable:
• connects the IFEU to MRAU(s) and the MRAU(s) to the SRAU(s)
• transmits (FWD) multiband and receives (REV) IF signals
• delivers DC electrical power to the RAUs. The Spectrum IFEU DC voltage output
is 54VDC nominal. If the IFEU reaches its current limit, a current-limiting circuit
protects it.
• carries configuration and status information
• uses 75 type-F connectors with captive centerpins.
CATV Cable Requirements
Belden CATV cable or equivalent is required (see Figure 2).
• For the RG-6 cable, use a Belden 1695A Coax.
• For the RG-11 cable, use a Belden 7732A Coax.
NOTE:
ADC requires solid copper center conductor CATV cable for proper DC voltage to the RAU
and maximum distances.
