ADMONISHMENTS
Important safety admonishments are used throughout this manual to warn of possible hazards to
persons or equipment. An admonishment identifies a possible hazard and then explains what
may happen if the hazard is not avoided. The admonishments — in the form of Dangers,
Warnings, and Cautions — must be followed at all times.
These warnings are flagged by use of the triangular alert icon (seen below), and are listed in
descending order of severity of injury or damage and likelihood of occurrence.
Danger: Danger is used to indicate the presence of a hazard that will cause severe personal
injury, death, or substantial property damage if the hazard is not avoided.
Warning: Warning is used to indicate the presence of a hazard that can cause severe personal
injury, death, or substantial property damage if the hazard is not avoided.
Caution: Caution is used to indicate the presence of a hazard that will or can cause minor
personal injury or property damage if the hazard is not avoided.

GENERAL SAFETY PRECAUTIONS
-

Warning: 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.
Danger: 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. An optical power meter should be used to verify active fibers. A protective cap or hood
MUST be immediately placed 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 3 foot
(91.4 cm) minimum clearance from the antenna while the system is operating. Wherever
possible, shut down the RAN before servicing the antenna.
Caution: Always allow sufficient fiber length to permit routing of patch cords and pigtails
without severe bends. Fiber optic patch cords or pigtails may be permanently damaged if bent
or curved to a radius of less than 2 inches (5.1 cm).
Caution: Exterior surfaces of the RAN may be hot. Use caution during servicing.

SAFE WORKING DISTANCES
The Digivance NXD antenna, which is mounted on top of a pole, radiates radio frequency
energy.
For the occupational worker, safe working distance from the antenna depends on the workers
location with respect to the antenna and the number of wireless service providers being serviced
by that antenna.
Emission limits are from OET Bulletin 65 Edition 97-01, Table 1 A.

STANDARDS CERTIFICATION
FCC: The Digivance NXD complies with the applicable sections of Title 47 CFR Part 15, 22,
24 and 90.
The Digivance NXD Hub has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference to
radio communications.
Changes and modifications not expressly approved by the manufacturer or registrant of this
equipment can void your authority to operate this equipment under Federal Communications
Commissions rules.
In order to maintain compliance with FCC regulations, shielded cables must be used with this
equipment. Operation with non-approved equipment or unshielded cables is likely to result in

PRODUCT DESCRIPTION
This section describes the Digivance Neutral Host (NXD) Radio Access Node (RAN).

1.1

General Description
The RAN, shown in Figure 1, is the remote component in the Digivance NXD Multi-Band
Distributed Antenna System. The RAN is a pole-mounted or pad-mounted, weather-resistent
cabinet, housing electronic modules that operate on an internal cPCI backplane. Included are a
central processing unit, a system interface, an optical interface, optical to RF data converters,
RF multicouplers, and DC power supplies. The RAN also houses rectifiers, backup batteries,
power amplifiers, and optical wave division multiplexers. Optical and RF functions are both
required because the RAN exchanges data with the system Hub using an optical link and
exchanges data with wireless users using RF signals. Each RAN provides the system with an RF
antenna and can accommodate up to four bands (PCS A-F, SMR A, Cell A”/A, or Cell B/B’). Dual
RANs installed at the same location can accommodate up to eight bands using a common
antenna.

1.2

System Function
The NXD Distributed Antenna System (DAS), in which the RAN is the remote component, is a
multi-frequency, multi-protocol RF access network providing microcellular Cellular and PCS
coverage via a distributed RF access system. In a typical configuration, such as shown in
Figure 2, multiple RANs are connected to a central Hub where multiple Base Transceiver
Station (BTS) interfaces are located. Signals received at the Hub are distributed to the RANs in
digital form by way of a fiber optical link. Within the RANs, the signals are converted from
digital to RF format to be transmitted from the RAN antennas. Signals also travel in a reverse
direction, from the RANs to the Hub, with a reverse data conversion.
Physically, the DAS consists primarily of electronic modules located in the Hub and RANs. At
the Hub, these modules are mounted in an equipment rack typically housed in a common
telecommunications structure with the base station electronics for Wireless Service Providers
(WSPs), either in the same room or nearby. These modules include high power attenuators, base
station modules, a power distribution unit, an Ethernet hub, a Hub reference module, an RF
chassis, and one or more digital chassis. The RAN electronic modules, mounted in the RAN
cabinet, perform the remote system functions of optical to RF data conversion and RF access.
These modules are described in subsequent topics within this product description. Digivance
Element Management System (EMS) software, running on a computer located at the Hub,
provides a graphical user interface to monitor system performance.

High-Level View
The RAN consists of the main components shown in a high-level view in Figure 3. These
components include:
• RAN Cabinet: exterior shell of the RAN containing cable connection points, ground
studs, and slots or shelves supporting other RAN components.
• RAN Chassis: standard Compact PCI (cPCI) shelf capable of housing 21 industry
standard cPCI circuit card modules. The modules are plugged into a common backplane
providing data bussing between them.
• Related Electronics: including rectifiers, Power Amplifier Assemblies (PAAs), batteries,
multiplexers, and a circuit breaker panel.
All components called out in the figure except for the multiplexers are separately installable in
the field. In most cases, however, the RAN is shipped with a basic set of components having
been ordered in advance by the customer and installed in the factory.

Note: 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 cause
interference to adjacent band users. The power reduction is to be by means of input power
or gain reduction and not by an attenuator at the output of the device.

RAN Cabinet
The RAN cabinet is a NEMA-3R enclosure designed to protect its electronic components from
weather and human tampering. The cabinet is weather-tight but contact with salt-air mist should
be avoided as it may decrease the mean time between failure of some components. The cabinet
has ventilation openings to allow entry of cool air and escape of hot air. The cabinet provides

Page 8
© 2007, ADC Telecommunications, Inc.

ADCP-75-210 • Issue 1 • March 2007

termination points for the coaxial antenna cable, fiber optic cable, ground cable, and AC cable.
The cabinet has inbuilt AC power surge protection and limited storage for fiber optic cables.
1.6.1

Mounting

The RAN cabinet may be mounted on a wood pole or on a concrete pad. Mounting bracket kits
(available from ADC) are required for each type of installation.
1.6.2

Fiber Optic Cable Entry

A nylon connector is provided on the rear of the RAN cabinet for routing a fiber optic cable into
the cabinet. The cord connector provides cable strain relief and a watertight seal at the fiber
optic cable entry point. As the connector nut is tightened, a soft neoprene bushing compresses to
tightly grip the cable without applying excessive force to the fibers. The connector
accommodates cables of a diameter in the range .38 to .50 inches (.97 to 1.27 cm).
Note: If the installer has a larger cable, the manufacturer (Hubbell Inc.) makes bushings
that fit this connector in the following size ranges: .500-.625, .625-.750, .750-.875, .8751.00, 1.00-1.125 inches.

In a typical installation, the connectorized end of a multi-fiber OSP cable is routed into the
cabinet through the cord connector and the individual fibers are connected to the optical
transceiver on the Synchronous Interface Card (SIF). Excess slack is stored inside the cabinet.
The stub end of the cable is routed to an external splice enclosure (not provided) for splicing to
the outside plant fiber optic cable.
1.6.3

Antenna Cable Connections

Five N-type plugs are provided on the rear of the RAN cabinet for connecting the antenna
coaxial cables. On the inside of the cabinet, coaxial jumper cables (included with the cabinet)
are used for connecting to the antenna port on the appropriate multiplexer.
1.6.4

AC Power Wiring Entry and Grounding

The NXD RAN uses 240 VAC power. A one inch (2.54 cm), 90 degree rigid elbow conduit
fitting is provided on the rear of the cabinet. The conduit should be routed to an external
junction box (not provided). It is suggested that an external AC outlet (not provided) be installed
near the cabinet to power test equipment and power tools. The AC source should supply 50/60
Hz, single-phase power through a circuit breaker rated at 20 Amps.
1.6.5

Ventilation

Ventilation openings are provided in the front door of the RAN cabinet to permit entry of air for
cooling. A filter removes dirt particles so that only clean air enters the cabinet. The heated air
exits the cabinet through the rear side. The four PAAs are each equipped with three cooling fans
that pull air through the module and exhaust it to the rear of the cabinet. A fan assembly at the
top of the RAN chassis forces the air out the rear side of the cabinet.

RAN Chassis and Electronic Modules
The RAN chassis, shown in Figure 6, is a standard Compact PCI (cPCI) shelf capable of
housing 21 industry standard cPCI circuit cards (called “electronic modules” in this manual).
The backplane supports the basic cPCI functions and it has been extended to allow the routing
of DIFTM, reference clocks and I2C signals between I2C modules. The RAN chassis also houses
cooling fans within the Fan Access Panel on the top of the chassis. Table 3 identifies the
electronic modules using the callout reference numbers from Figure 6.

Figure 7 is a schematic showing the data flow in the RAN chassis, as represented by the PCS-A
band. As shown, data flows in two directions, from the Hub through the RAN to the antenna,
and from the antenna through the RAN back to the Hub. In each direction, data conversion
occurs, with optical data “upconverted” to RF data in the up direction in the schematic, and RF
data “downconverted” to optical data in the down direction. In an up direction, the RUC module
converts Digitized Intermediate Frequency (DIF) data into PCS, Cellular, and SMR frequency
RF bands. The RF signals are amplified and then transmitted from the RF antenna. In the down
direction, the RDC module converts PCS, Cellular, and SMR frequency bands into DIF data.
The overall series of events is managed by the CPU using an Ethernet connection to the chassis
backplane.

Power Amplifier Assembly
The Power Amplifier Assembly (PAA) is an electronic device that amplifies RF signals in the
forward path just before they are transmitted to the RAN antenna. Up to four PAAs may be
mounted in the RAN, each providing one band. Each PAA consists of a Power Amplifier (PA), a
control board called the PA Interface Controller (PIC), and a cooling system. The PA is multichannel. Different units are used for PCS, Cellular, and SMR 800 bands.
The PIC interfaces to the discrete signals of the PA. The PIC also provides DC power to the PA
by converting from -48 VDC to +12 VDC or +28 VDC depending upon which PA is being used.
Each PA has its own PIC. The PIC is managed is managed by the CPU over an I2C connection
through its corresponding RUC. The cooling system consists of a heat sink and three fans that
provide cooling for the PA by blowing external air across the heat sink. The fans are softwarecontrolled. The PIC module monitors the tachometer outputs of the fan.
Figure 20 shows the PA assembly connection points and indicators. Table 14 describes the items
called out in the figure.

1.12 Backup Batteries
The NXD RAN has two backup battery options:
• Extended Batteries: provide backup protection for up to two hours. These are four 12V,
85-100 AH internal batteries connected in series for a -48V system. The four batteries
together with associated wiring and hardware weigh 325 pounds (147.7 kg).
• Glitch Batteries: provide backup protection for up to five minutes. These are small,
motorcycle type batteries connected in a series configuration.

1.13 Antenna
ADC provides a pole-mount antenna kit for use when the RAN is mounted on a wooden utility
pole. The kit must be separately ordered from the RAN. Pole mounting is the most common
type of RAN installation.
The antenna offered interfaces with the PCS and Cellular/SMR bands and supports two branch
diversity receive paths. Also included in the kit is the GPS antenna used by the RAN.
The RAN may also be mounted outdoors on a concrete pad. This type of installation may use a
conventional directional antenna in either a sector or quasi-omni antenna configuration,
depending on the coverage objective and design. Proper antenna selection and the mounting
installation are the responsibility of the design engineer.
Antenna installation is covered in separate publications, available for downloading from the
ADC web site, www.adc.com. Refer to RELATED PUBLICATIONS on Page vii.

STANDARD INSTALLATION PROCEDURES
This section provides the standard procedures for a typical installation. The RAN may be
installed either on a wooden pole or on a concrete pad.
This section is organized as follows:
• Sections 2-1 through 2-4 provide information that is relevant before installing the cabinet.
These subsections contain an installation overview, unpacking instructions, a list of
required material and tools, and site preparation guidelines.
• Section 2-5 tells how to install a cabinet on a wooden utility pole. Included are instructions
for installing the pole mount bracket and then installing the cabinet on the bracket. Also
included are instructions for installing the rain shields.
• Section 2-6 tells how to install the RAN on a concrete pad. Included are instructions for
pouring the concrete pad, mounting the RAN on the pad, and installing the pedestal
enclosure.
• Section 2-7 contains other standard procedures typically done at every installation. These
procedures describe how to install the solar shield, grounding wire, RF cables, fiber optic
cable, AC power, and backup batteries.
Note: Section 3 contains instructions for installing a second RAN at the same location.
Section 4 provides information on non-standard installation procedures such as installing
an electronic module.
Installation of the RAN cabinet may proceed separately from the installation of the
corresponding Hub equipment. When the installation of the RAN is completed, refer to the
Digivance NXD Multi-Band Distributed Antenna System Operation Manual (ADCP-75-209)
for system turn-up and test procedures.
The procedures in this section assume that the required Outside Plant (OSP) fiber optic cable
has already been routed between the Hub and the RAN, that the required antenna has been
installed, and that a coaxial cable terminated with an N-type connector has been routed to the
RAN from the antenna.
Danger: 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: Always allow sufficient fiber length to permit routing of patch cords and pigtails
without severe bends. Some fiber optic patch cords or pigtails may be permanently damaged if
bent or curved to a radius of less than 2 inches (50 mm).

2.1

Installation Overview
A standard (typical) installation of the RAN consists of the following steps:
Warning: Electronic components can be damaged by static electrical discharge. To prevent
ESD damage, always wear an ESD wrist strap when handling electronic components.

Site Preparation
This section describes site preparation for installation and is presented only as a guideline for a
typical RAN installation.
2.4.1

Space Requirements

When an installation site for the RAN is selected, either on a utility pole or concrete pad, care
must be exercised to ensure that the site provides adequate space and clearance to accommodate
the current installation and any future upgrades. Table 17 gives RAN dimensions.

ADCP-75-210 • Issue 1 • March 2007

31.25 in. (76.7 cm)

73 in. (185.4 cm)

27.5 in. (69.9 cm)

2.4.2

Power Requirements

Power must be available at the RAN site. The RAN requires 240 VAC, single phase, 20 Amps
service. Included with the power meter must be surge protection and circuit breakers.
The RAN can have up to three 1500 watt rectifiers. For the minimum specified voltage (176
VAC), each can draw up to 10 amps. The RAN will draw up to 1800 watts normally, but when
batteries are re-charging that amount will increase the current draw into a RAN to up to 16
Amps. Therefore, one 20 Amps service is required per four band RAN.
In a pole mount installation, the power meter is typically installed on the pole below the unit in
separate boxes. In a concrete pad installation, an external junction box is typically placed near
the RAN providing AC power, surge protection, and circuit breakers.
2.4.3

Antenna Requirement

ADC offers a pole-mount antenna kit (accessory) for use when the RAN is mounted on a
wooden utility pole. Either a 2 in. (5.08 cm) O.D. model or a 9 in. (22.86 cm) O.D. model can
be ordered. Pole mounting is the most common installation. The antenna interfaces with the
PCS and Cellular/SMR bands and supports two branch diversity receive paths. Also included in
the kit is the GPS antenna used by the RAN. Installation instructions for the pole mount antenna
are included with the kit.
When the RAN is mounted on a concrete pad, a conventional directional antenna may be used
(customer supplied). The antenna may be set to operate in either a sector or quasi-omni
configuration, depending on the coverage objective and design. Proper antenna selection and the
mounting installation are the responsibility of the design engineer.
2.4.4

RF Cable Requirements

RF cables are required at the installation site to provide the physical link between the RAN and
the antenna. In a pole-mount installation, U-duct of an appropriate size is also required to cover
the RF cables on the pole. The U-duct provides only physical protection. It should not be
considered to provide electrical isolation from conductors on the pole. Adequate clearance must
be obtained for the routing of these cables past the existing services as defined in the previous
topic. In a concrete pad installation, RF cables from the antenna are routed and protected per the
installation plan provided by the design engineer.

ADCP-75-210 • Issue 1 • March 2007

2.4.5

Fiber Requirements

Optical fibers are required at the site to provide the physical link between the RAN and the Hub.
In a typical installation, the identified fibers are broken out of a multi-fiber sheath and routed to
a splice box where they are spliced to pigtails connecting the main sheath to the RAN. The
actual fiber bundle location on the utility pole may vary per the agreed to attachment point.
Refer to Figure 25. The nylon cable connector on the rear of the RAN accommodates cables of
a diameter in the range .38 to .50 inches (.97 to 1.27 cm). For larger size cables, refer to
Section 1.6.2 on Page 9.

2.5

Installing a RAN Cabinet on a Wooden Utility Pole
Figure 25 shows the main components and their spatial placement in a typical NXD RAN pole
mount installation.
2.5.1

Site Requirements Unique to Pole Mounting Locations

If power lines are present at the top of the pole, spacing requirements applicable to the RF
cabling and any other hardware installed in the electric space must be considered. Per the
National Electrical Safety Code, vertical clearance at supports for primary-supply conductors
above other facilities is required to be 16 in. (40.64 cm) above neutrals and 40 in. (101.6 cm)
above communications (60 in. [152.4 cm] if above 8700V).
For supply conductors at voltages up to 8700 between conductors, the minimum horizontal
clearance provided by the NESC ANSI C2 is 12 in. (30.5 cm). For higher voltages, it is required
that .4 in. (10.2 mm) be added for every 1000V above 8700. Table 18 lists the required
clearances for some common high voltages.

Pole Loading Analysis

A pole loading analysis should be performed before the RAN is mounted on the pole to verify
that the pole can support the weight of the RAN in various conditions. The analysis should take
into account the pole top antenna, the RAN and batteries, and the possibility of an expansion
RAN with batteries. Table 19 lists the weights of various NXD components and configurations.

Three load types should be considered: static weight loading, ice loading, and wind loading.
These types should be considered on the pole, wires, and any equipment installed on the pole.
A qualified engineer should perform the pole loading analysis, taking into account both vertical
and horizontal forces. The specified horizontal load is applied 2 ft. (60.1 cm) from the top and
the assumption is that the pole acts as a cantilever with maximum stresses applied at the ground
level. Table 20 provides acceptable loads by pole class.

Installing RF Cabling

RF cabling on the RAN connects the RF antenna to the RF input on the back of the RAN. There
are five Type N receptacles on the antenna and five Type N receptacles on the back of the RAN,
identified in Table 21 on page 47.
There are two main steps in installing RF cables: weatherproofing the cables, and routing and
securing the cables.

ADCP-75-210 • Issue 1 • March 2007

2.7.3.1

Weatherproofing RF Cables

RF cables should be weatherproofed before being installed. The following materials are
required (customer supplied):
Note: Read and understand the manufacturer’s instructions prior to using these products.
• 3M 8426-9M cold shrink
• 3M Skothkote Electrical Coating 14853
Use the following procedure to weatherproof the RF cables:
1. Prior to connecting the RF cables to either the RAN or antenna, place one 3M 8426-9M
cold shrink kit over the cable end, then connect the cable end to its intended termination
point. Follow the manufacturer’s directions, which are included with each kit.
2. After the cold shrink has been applied, coat the entire length of the cold shrink material
with the 3M Scotchkote Electrical Coating, number 14853.
2.7.3.2

Routing and Securing RF Cables

For cable installation, the following materials are required (customer supplied):
• 10 Type N male plugs (CommScope PN: 540ANM or equivalent)
• Coax cable (CommScope PN: FXL540OPE or equivalent)
• Electrician’s tape
• Water seal
Use the following procedure to route and secure the RF cabling:
1. Measure from the antenna base connectors to the RAN connectors to determine the coax
cable length including service loops and drip loops. Refer to Figure 25 on Page 35.
2. Install the Type N plugs on each end of each of the RF cables.
Note: Right angle connectors may not be needed if there is enough space or if the coax
cable is flexible enough to create a proper bend radius in the cable. Reference the coax
cable manufacturer specifications for allowable bend radii.
Note: A cable sweep test is highly recommended. When testing the RF and GPS coaxial
cables, use a matched load. The VSWR should be 1:1:1. The return loss should be 26.444
dB or better.
3. Attach each end of the cables to the appropriate connectors on the antenna base and the
RAN. Refer to Figure 33 and Table 21.
4. Tighten each connector to 20 ft.-lbs.
5. After each connector is tightened, cover the entire connection with electrician’s tape, then
wrap the connection in water seal and finally cover the water seal with wraps of
electrician’s tape.

2.7.4

Installing Pre-Connectorized Indoor/Outdoor Fiber Optic Cable

Fiber optic cable installation consists of routing a pre-connectorized outdoor-rated fiber optic
cable from an external splice enclosure to the NXD RAN cabinet, routing the cable into the
cabinet, and then breaking out the individual fibers for connection. The NXD RAN has a fiber
interface on the front of the Synchronous Interface (SIF) Module in the RAN chassis. The fiber
enters the cabinet on the rear side.

ADCP-75-210 • Issue 1 • March 2007

All fiber optic cable connections require single-mode Dual-LC type connectors.
Figure 34 shows the basic configuration of the optical path between the Hub SIF and the RAN
SIF. For optical specifications, refer to Table 2 on page 6.

Figure 34. Optical Path Between Hub SIF and RAN SIF

For fiber cable ingress, the RAN is equipped with a nylon fiber optic connector located on the
rear side of the cabinet. The connector accommodates cables of a diameter in the range .38 to
.50 inches (.97 to 1.27 cm).
Note: If the installer has a larger cable, the manufacturer (Hubbell Inc.) makes bushings
that fit this connector in the following size ranges: .500-.625, .625-.750, .750-.875, .8751.00, 1.00-1.125 inches.

Use the following procedure to install the fiber optic cable:
Note: The routing of an Outside Plant (OSP) fiber optic cable from the Hub to a splice
enclosure in the vicinity of the RAN cabinet and the splicing of selected OSP cable fibers
to the fibers in the outdoor-rated cable is the responsibility of the installer.
Warning: 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 transmitter of any unit or exposure to laser radiation may result.
An optical power meter should be used to verify active fibers. A protective cap or hood MUST
be immediately placed over any radiating transmitter or optical fiber connector to avoid the
potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles
from entering the connector.
1. Route the connectorized end of the fiber optic cable from the splice enclosure (not
provided) to the rear side of the cabinet. Estimated length of cable is 30 feet (9 meters)
although this is dependent upon distance from the splice enclosure.

ADCP-75-210 • Issue 1 • March 2007

Note: The fiber should not have armored jacketing which may be a source for ElectroMagnetic Interference (EMI).
2. Install the compression nut and an appropriate sized split ring and bushing over the cable
end. Note that the beveled side of the split ring should face toward the compression nut.
3. Insert the end of the cable into the fiber entry opening on the bottom of the cabinet and
pull the cable into the cabinet.
4. Connect fiber to the LC receptor located on the SIF electronic module. For location, refer
to Figure 11 on Page 16.
5. Pull back any excess fiber from within the NXD cabinet.
6. Tighten the compression nut on the fiber entry connector body to secure the cable.
7. Seal all connections.
2.7.5

Installing AC Power
Note: Power interfacing for the RAN must be performed by a licensed electrician.

Prime power for the RAN is 240 VAC, 20 Amps, single phase. A separate service disconnect
and lightning arrestor for each RAN must be installed with proper grounding. An electric meter
is optional depending on local agreements.
A non-connectorized #14 AWG 3-wire power cable is provided with the RAN cabinet for the
AC power connections. The power cable is connected to a wiring harness within the cabinet and
is approximately 20 feet (6 meters) long. The stub end of the cable must be routed out of the
cabinet through conduit to an external junction box (not provided). At the junction box, the
power cable must be connected to the AC power system wiring. The RAN electrical input fitting
is located on the right rear of the cabinet, labeled “AC.”
The AC power cable provides three wire leads for Line, Neutral, and Ground connections. All
AC wires must be run within conduit. The interface at the RAN is a 1 in. (2.54 cm) 90 degree
receptor elbow.
For installation of AC power, the following materials are required (customer provided):
• Electrical conduit
• Conduit fittings
• Connector sealant material
The following tools are required to perform this procedure:
• Wire cutters
• Wire strippers
• Conduit cutter
• Conduit bender

ADCP-75-210 • Issue 1 • March 2007

Note: All electrical work must comply with local codes and requirements. A locally
licensed electrical contractor is best qualified to perform this work. For operation at less
than 20 Amps, consult with ADC Technical Service.
Danger: Use extreme caution when working with high voltage AC power. Ensure all power is
disconnected before working on power circuits.
Use the following procedure to install the AC power wiring:
1. Install outdoor conduit between the the AC power junction box and the AC power fitting
(rigid 90 degree receptor elbow) on the back of the cabinet.
2. Use a UL approved outdoor conduit connector (not provided) to connect the conduit to the
AC power junction box.
Note: A reducer fitting must be provided to accommodate any size change to the conduit.
3. Route the AC power cable through the conduit to the AC junction box.

MAINTENANCE PROCEDURES
This section provides procedures for completing various maintenance tasks at the RAN. Refer
to the procedures in this section as necessary when scheduled maintenance is required. For fault
and troubleshooting procedures, refer to the system operation and maintenance manual, ADCP75-209.

5.1

cPCI Fan Replacement Procedure
The RAN chassis is equipped with a cooling fan that exhausts heated air from the chassis
assembly. Cool air enters the cPCI chassis through vent openings on the front door of the
cabinet. The recommended replacement interval is 60 months.
Use the following procedure to remove and replace the cPCI cooling fan.
1. Loosen the two thumbscrews that secure the fan access panel front door.
2. Open the hinged door (it swings down) to access the fan compartment.
3. Slide out the fan being replaced, note how it is connected, and then disconnect the fan.
4. Connect the new fan like the previous fan and slide it into the fan compartment.
5. Verify that the fan is running properly.
6. Close the fan panel door and secure it with the thumbscrews.

5.2

Cleaning or Replacing an Air Inlet Filter
The RAN cabinet air filter cleans the intake air before it enters the cabinets. The filter should be
cleaned approximately once per year and more often in extremely dirty environments. If the
