RF Safety
To comply with FCC RF exposure compliance requirement, adhere to the following warnings:
Warning! Antennas used for this product must be fixed mounted on indoor permanent structures, providing a
separation distance of at least
75 cm from all persons during normal operation.
Warning! Each individual antenna used for this transmitter must be installed to provide a minimum separation
distance of 75 cm or more from all persons and must not be co-located with any other antenna for meeting RF
exposure requirements.
Warning! Antenna gain should not exceed 12.5 dBi.
Warning! The design of the antenna installation needs to be implemented in such a way so as to ensure RF
radiation safety levels and non-environmental pollution during operation.
ATTENTION
Compliance with RF safety requirements:
• MobileAccess products have no inherent
significant RF radiation
• The RF level on the d ownlink is ve ry low a t
the downlink ports. Therefore, there is no
dangerous RF radiation when the antenna
is not connected.
CAUTION
Use of controls, adjustments or performance of
procedures other than those specified herein may
result in hazardous radiation exposure.

Laser Safety
Fiber optic ports of the MobileAccessQX system
emit invisible laser radiation at the 1310/1550 nm
wavelength window.
The laser apertures /outputs are the green
SC/APC Bulkhead adapters located on the front
panel of the equipment.
External optical power is less than 10 mW,
Internal optical power is less than 500 mW.
To avoid eye injury never look directly into the
optical ports, patchcords or optical cables. Do not
stare into beam or view directly with optical
instruments. Always assume that optical outputs
are on.
Only technicians familiar with fiber optic safety
practices and procedures should perform optical
fiber connections and disconnections of
MobileAccessQX devices and the associated
cables.
Care of Fiber Optic Connectors
Do not remove the protective covers on the fiber
optic connectors until a connection is ready to be
made. Do not leave connectors uncovered when
not connected.
The tip of the fiber optic connector should not
come into contact with any object or dust.
Refer to the cleaning procedure for information
on the cleaning of the fiber tip.
MobileAccessQX has been tested and certified as
a Class 1 Laser product to IEC/EN 60825-1
(2007). It also meets the requirements for a
Hazard Level 1 laser product to IEC/EN 60825-2:
2004 to the same degree.
MobileAccessQX complies with 21 CFR 1040.10
and 1040.11 except for deviations pursuant to
Laser Notice NO. 50 (2007).
MobileAccessQX employs a Class 3B laser and
therefore the following label is affixed inside the
unit adjacent to the laser:

MA2000 QX operates along with an SCU-F
unit, which converges the services from one
or more MA2000 QX units and provides the
interface to the DAS infrastructure. Both QX
and SCU-F are described in this manual.

Introduction I P/N: 709C0011101I Page 1
1.2 System Architecture
The QX and SCU-F are located at the floor level remote end. QX receives RF over optic service
signals from the head end, reconverts the signals to RF over copper, adjusts them to the
required level and outputs each service to dedicated interfaces. The signals are combined by
the SCU-F (along with services from other QX units) and distributed over a common DAS
(Distributed Antenna System) infrastructure.
In the uplink, cellular service signals received at the DAS are separated by the SCU-F and
routed to their dedicated QX ports. The signals are then converted to optic and forwarded to
the head-end for reconversion to RF and distribution to the relevant BTS or BDA systems.
Note: 3rd party equipment is sold separately (i.e. cabling, antennas).
QX Architecture Diagram Figure 1-2
Headend:
At the headend CMA elements provide interface to the wireless service provider’s network,
condition the signals and convert them to optical signals for transportation over fiber optics
towards the rem ote ends.
• Radio Interfac e Unit (RIU) - the RIU conditions and custom tunes the RF Downlink (DL)
signals from an ope rator’s si gnal source (BTS o r BDA) to ensu re a con stant RF level . In the
Uplink (UL), the signal (at the required level) is routed back to the operator’s signal source.
System Architecture I P/N 709C011101 I Page 2
• RF to Optic converter unit – this can eit her be a Base Un it (BU) or an Optic al Contro l
Head End Unit (OCH), where th e OCH is QX model speci fic. These are wideband units that
convert the RF Downlink (DL) signals from the RIU into optical signals for routing over
single or multi-mode fiber optic cabling (SMF/MMF) to/from the QX units located at the
remote locations up to 2Km away.
• System Controller (SC-450) - the system controller enables centralized remote
management and control of MobileAccess elements. This unit connects directly to the RIU
and BU and/ or OC H an d all ow s man agem en t o f t hese as wel l as th ei r host ed el e ments (e.g.
QX) via a controller Web session.
Remote End:
At the remote end, the optical signal is reconverted to RF, filtered, amplified to the appropriate
level, combined with other signals and distributed over the b roadband antenna infrastructure.
The QX unit is installed, along with the Four Port Service Combiner Unit (SCU-F). The QX
system remote end consists of the following elements:
• QX - each QX unit provides coverage for four RF services (e.g. CELL, PCS, 700LTE and
AWS) via two types of service dedicated internal modules (RHU and AO). Each of these
modules is monitored via the Controller as an independent unit.
• Service Combiner Unit (SCU-F): a passive module that combines and distributes the UL
and DL signals from one or more QX units to (up to) four broadband antennas.

1.3.2 QX Main Internal Modules
The QX main components consist of the following internal modules:
• Remote Hub Unit (RHU) – servi ce speci fic u nit , supports t wo voi ce ser vices, c onverts t he
optical signals received from the BU/OCH to RF signals (and vice versa) an d routes t hem t o
the coax antenna infrastructure (via the Four Port Service Combiner Unit – SCU-F).
• Add-On (AO) – adds an additional voice service to the host RHU (QX includes two AO
modules hosted by the RHU)
Note: The voice services are combined by the connected Service Combiner Unit (SCU).
• Antenna Mon itor ing Un it (AM U) – digital unit that enables antenna monitoring and relay
messaging of the following information:
• Antenna status
• Fans status
• Fans control
• AMU/QX alarms.
The AMU is connected to the SCU. The AMU modules of a number of QX units can be daisy
chained to a single SCU-F (see section
3.5.2.1).
• Fan Module – two extractable fans, simple to maintain and replace (see section
4.2).

2 Installation Guidelines
2.1 Infrastructure Prepar ati on
This following installation rules are based on the assumption that site survey and installation
planning (including power requirements) have been completed.
2.2 Installation Requ irements
The infrastructure preparation consists of two main phases:
Floor Planning : Planning the distribution of the antennas on each floor to provide the required
coverage.
Telecom Closet Planning : Planni ng the l ayout of th e devices an d cabl es in the tel ecom clos et
or shaft.
2.3 Coaxial Cable Connections
2.3.1 General Cable Installat ion Procedures
Observe the general cable installation procedures that meet with the building codes in your
area. The building code requires that all cabling be installed above ceiling level (where
applicable). The length of cable f rom the risers t o each antenna mu st be conceal ed above the
ceiling.
The cable must be properly supported and maintained straight using tie-wraps, cable trays and
clamps or hangers every 10 feet (where practical above ceiling level). Where this is not
practical, the following should be observed:
• The minimum bending radius of 7” is required for the supplied ½” coax cable.
• Cable that is kinked or has a bending radius smaller tha n 7” must be replaced.
• Cable runs that span less than two floors should be s ecured to suit ably located mechan ical
structures.
• The cables should be supported only from the building structure.
