1.3 Product Purpose and Description

Boxer is a compact, actively‐cooled, GR‐487 Issue 4‐compliant

outdoor cabinet that can house and protect a wide range of

electronic equipment. Up to 10 vertical RUs (17.5”) of 19‐inch

wide internal rack space is available to house Network equip

ment such as (but not limited to) multiplexers, copper bonding

solutions, Ethernet switches and media converters, xDSL

boxes, and DS3 hand‐offs. Protectively mounted on the Boxer

front door, separate from the interior rack space, is a heat ex

changer and fan unit. Mounted on the inside left wall is a

controller card with factory‐installed wiring for the fans, tem

perature and door alarms, and a 5A fan fuse. External wiring

at the card from the power source and alarm monitoring equip

ment is accomplished using “Euro‐connector” snap‐in

terminal blocks on the card which can be quickly disconnected

and later re‐attached for easy connections.

Boxer supports rapid equipment installation and wiring

through the use of adjustable and removable 19” rack channels.

An access panel is located at the rear of Boxer to allow easy ac

cess to the rear of the installed equipment. To ensure easy

access for input and out cabling, Boxer includes ample room

below the rack space as well as various sized conduit knock‐

outs.

1.4 Product Mounting

The Boxer cabinet is typically mounted outdoors, above

ground, on an H‐frame or wall. Optional mounting kits are

available to support a round pole (from 8” to 20” in diameter)

or a square pedestal or post (minimum 8” wide). Concrete pad

mounting is supported when used with the optional Boxer bat

2. FEATURES

This section describes the exterior and interior features of the

WestellrBoxerroutdoor cabinet in more detail. Refer to

Figure 2 through Figure 6 as needed while reading this section.

2.1 Exterior Features

The features located outside the large main cabinet are de

scribed hereunder. See Paragraph 2.2 for the interior features.

2.1.1 Construction and Materials

The Boxer cabinet is designed to be weather‐tight for above‐

ground applications. As such, the powder‐coat painted alumi

num cabinet withstands many harsh weather conditions such as

rain, snow, and sleet.

2.1.2 Cabinet

The cabinet utilizes an “in‐the‐door” heat exchanger design.

Cabinet cooling is accomplished through the front‐door‐

mounted heat exchanger, fans, and vents. Security is provided

via a tamper‐proof lock. Side‐wall lift ears (Paragraph 2.1.2.4)

are provided for temporary installation lift‐assistance. Mount

ing brackets (Paragraph 2.1.2.3) are attached at the top and

bottom of the back wall for permanent mounting. The bottom

floor of the main cabinet contains numerous, differently‐sized,

intact knock‐outs (Paragraph 2.1.2.7) to accommodate a variety

of cable, fitting, or conduit sizes and types.

2.1.2.1 Large Cabinet Door

A full‐size locking door provides ample technician and equip

ment access to the interior of the cabinet and also helps protect

the cabinet from tampering and vandalism. When the cabinet is

mounted and the door is open, the minimum clearance or dis

tance from the back of the mounting brackets to the outer edge

of the door's lock flange is 43.4” (shown in Figure 26). The cabi

net's cooling system is based in the door, with screened vents, a

heat exchanger and fans mounted on the door. At the inside bot

tom of the door, near the hinge, a wind‐latch, shown in Figure 2

and Figure 3, protects the door (and technician) from possible

wind damage. The wind latch restricts the door's swing‐out angle

to a safe but functional opening (95 degrees). In the closed posi

tion, a gasket installed around the inside perimeter of the

cabinet door compresses against the cabinet's door frame; when

both hex cup‐washer screws (or pin‐in‐hex screws on the

‐NHE3G) are tightened, the door and gasket provide a weather‐

tight seal to protect all equipment installed inside the cabinet.

The door open sensor switch is described in Paragraph 2.2.1.

2.1.2.2 Lock(s) for Door and Rear Access Panel

To lock the door and rear access panel, tamper‐proof screws are

provided. The cup‐washer screws on the ‐NHE3 model are loos

Section BXM‐10N‐HE3‐20A 030‐101741 Rev. B R

41311IARB

ened and tightened with a can wrench or 216 tool, and the

pin‐in‐hex screws are loosened and tightened with a pin‐in‐hex

wrench (wrench provided with the ‐NHE3G). In addition to pro

viding security, when fully‐tightened, these screws help to seal

the cabinet and protect the interior environment from outside

elements or contaminants by compressing the door/panel's seal

ing gasket(s). Additional security is offered for the door via holes

in the door flanges which accept a field‐provided lock or pad

lock.

2.1.2.3 Mounting Brackets

Full‐width molded mounting brackets are provided at the back

wall of the Boxer cabinet, one at the top and one at the bottom.

Each bracket has nine mounting holes (top bracket) or slots

(bottom bracket). Use mounting fasteners with a diameter of up

to 3/8”. The horizontal distance between holes is shown in

Figure 27. The vertical distance between the top and bottom

mounting bracket holes is 25.2”.

2.1.2.4 Side Lift Ears

The Boxer cabinet is equipped with two external lift ears or

brackets, one on each side, attached at the top of the cabinet.

These lift ears can be used to lift the cabinet using lift equip

ment, for mounting purposes. Each ear has a hole with a 2”

diameter, to accommodate various cable, strap, or hook sizes.

Always use two straps of equal lengths, one for each lift ear,

when using this method to lift the cabinet. Do not use the lift ears

for permanent mounting.

2.1.2.5 Rear‐Access Panel (Detachable)

A 10.5” x 19.5” rear‐access panel, shown in Figure 4, is located

at the rear of Boxer. The purpose of the access panel is to facili

tate equipment access, cabling, and servicing. A gasket on the

rear of the cabinet at the panel opening seals the panel open

ing. The rear‐access panel is secured with six cup‐washer

screws (on the ‐NHE3) or with six pin‐in‐hex screws (on the

‐NHE3G) and can be removed with a 216 tool or can wrench

(for the ‐NHE3) or a pin‐in hex wrench (provided with the

‐NHE3G).

2.1.2.6 AC Conduit Fitting

A 1/2” AC conduit fitting is provided on the exterior bottom

surface of the cabinet through a knock‐out hole near the back

right corner, to facilitate conduit attachment or power cable ac

cess. Inside the cabinet, the fitting is connected to an AC outlet

box immediately above it.

2.1.2.7 Bottom Floor Knock‐outs

Multiple knock‐outs are provided on the floor of the cabinet. One

near the center rear of the floor is for cable ingress and egress for

an optional battery cabinet that can be mounted below the Boxer

cabinet (or for Network cables). Provided on the right side of the

cabinet floor are multiple intact knock‐outs, for easy Network and

Customer cable access. The front three are typically for customer

cable access, and the rear‐most knock‐outs are typically for Net

work cable access. The knock‐out sizes and quantities are shown

in Table 1 and Figure 5. A “concentric” knock‐out is provided for

both Customer and Network access: depending upon which direc

tion the knock‐out is removed, either a 1/2” or 3/4” hole will be

produced. Do not remove a knock‐out unless it is absolutely nec

essary to do so for cable ingress and egress, and use either

tight‐fitting rubber grommets or liquid‐tight fittings, or other

proper and approved knock‐out hole sealants, to assure the best

internal air quality and weather‐resistance. Always use proper

and company‐approved tools to remove knock‐outs. There are

five, small, 0.575” diameter knock‐outs in the floor of the Boxer

cabinet where an optional battery box attaches to the cabinet

(hole patterns of both units match).

‐ KNOCK‐OUT REMOVAL NOTE ‐

Always remove knock‐outs where holes are desired before

mounting the cabinet or the optional battery box, regardless of

the type of knock‐out and the order of the mounting steps.

2.2.1 Door Sensor Switch

A door sensor switch is located at the bottom right corner of the

cabinet door opening (Figure 6). This switch is factory‐prewired

to the Controller Card for door alarm reporting purposes. To

temporarily disable the sensor, pull out the cylindrical door

switch actuator until it clicks. To re‐activate the sensor, either

gently push the actuator back in until a click is heard, or simply

close the cabinet door.

2.2.2 Internal 19” Rack Channels

Two removable/adjustable rack channels inside the cabinet pro

vide 19” relay rack mounting for equipment that is to be

mounted in the cabinet. Each channel is installed so approxi

mately 5” of equipment space is available from the inside of the

closed front door to the channel (for up to a 5” equipment pro

jection), and approximately 12” of equipment space is available

behind the channel to the rear cabinet wall. The channels can be

moved forward 2” or backward 3”, if a few additional inches of

equipment depth is needed at either the front or back of the

channel. Six channel positions are provided in the channel

bracket. Simply loosen the hex nut, lift and slide the channel

backward or forward the next slot position, then tighten the nut.

Both vertical rack channels contain predrilled holes, with stan

dard hole spacings (either 1”, 1.75”, or 2” rack hole patterns), to

mount customer‐supplied equipment in the cabinet. Network

equipment up to 10 Rack Units (10 RUs = 17.5”) high can be

mounted on the internal rack inside the cabinet, either as a

single piece or multiple pieces of equipment.

‐ LEFT CHANNEL NOTE ‐

Access to the controller card may be limited if one of the front‐

most channel mounting positions is chosen for the left channel.

2.2.3 Cooling System

The Boxer cabinet features an active heat‐exchange system that

compensates for the effects of internal equipment heat and ex

ternal solar and temperature loading inside the cabinet. The

heat exchanger fans are temperature activated. The fans turn

on when the interior of the cabinet reaches 35° C (95° F) and

turn off when the internal cabinet temperature cools to 25° C

(77° F). At the core of the heat exchange system are numerous

aluminum fins (best seen in Figure 2) on each “side” of a sealed

divider wall within the heat exchanger. The dual air‐path ex

changer uses one set of fans (shown in Figure 8) to blow cool

outside air past the “exterior air side” fins of the heat exchanger

and to direct the heated air out the screened holes on the sides

of the fan cover. Conversely, a second set of fans (shown in

Figure 2 and Figure 6) circulates warm inside air down past the

“interior air side” fins of the heat exchanger and blows cooled air

back through the main cabinet compartment. Both sets of fans

are field‐replaceable (see Table 4 for part numbers).

2.2.4 External‐Air Fans (“FAN A” Connector)

Two, factory‐installed, temperature‐controlled fans (shown in

Figure 8) to circulate cooler exterior air up through the heat ex

changer are located under the cover of the heat exchanger

compartment. These fans are factory‐wired to the “FAN‐A” con

nector on the controller card mounted on the left side wall of the

cabinet, and are powered from either a field‐provided +24VDC

power source or a ‐48VDC power source. To access or view the

fans, loosen the Phillips screw near the inside center of the door,

then lift off the cover off it's two posts.

2.2.5 Internal‐Air Fans (“FAN B” Connector)

Two, factory‐installed, temperature‐controlled fans (see

Figure 6) to circulate warm interior air down through the heat

exchanger and back into the cabinet are are located on the inside

of the cabinet door. These fans are factory‐wired to the

“FAN‐B” connector on the controller card mounted on the left

side wall of the cabinet, and are powered from either a field‐pro

vided +24VDC power source or a ‐48VDC power source.

2.2.6 Controller Card

This section and Table 2 describe the features of the controller

card. Internal wiring has been factory‐wired. See Paragraph 3.8

and 3.9 to perform external connections (installer power, temper

ature, and alarm wiring and connections) to the controller card.

Boxer includes a factory‐wired controller card located on the

inside left wall of the cabinet (Figure 9). The card includes con

nections for power and for the fans, temperature alarm, door

alarm, a fan test button and a 5A fan fuse. Internal wiring has

been factory‐wired. External wiring to the power source and

alarm monitoring equipment is done using “Euro‐connector”

snap‐in terminal blocks which can be disconnected from the con

troller card, and later re‐inserted for quick and easy connections.

Table 2 lists all of the connectors and positions on the controller

card. The only installer connections needed are the TEMP ALARM,

DOOR ALARM, and power connections (‐V and +V). To make

these connections to the Euro‐connectors, pull‐off the Euro‐

connector, loosen the screws inside the set‐screw holes, strip

approximately 3/8” off the end of each wire, insert wire(s) into

hole(s), tighten screws, and push‐on the Euro‐connector (see

Paragraph 3.8 and 3.9 for more installation details).

door of the Boxer cabinet to access the knock‐outs.

2. Remove knock‐out(s). Prior to mounting the cabinet, per

company practice, remove as many appropriately‐sized

knock‐outs at the bottom of the cabinet as needed for the

specific application (consider ground, power, and com

munication cable access needs, venting, and whether

optionally mounting a battery box with the cabinet).

3. Install rubber grommets or conduit fittings. Install either

a heavy‐duty rubber grommet or the conduit fitting of

choice (liquid‐tight recommended) in each selected

knock‐out hole. If an optional vent is desired, the provided

vent cap can be installed in one of the smaller knock‐outs.

4. Close the cabinet door. Once the knock‐outs are removed,

lock the door using the 216 tool or can wrench, to minimize

possible product damage and personal injury.

3.6 Mounting the Cabinet

The Boxer cabinet is typically mounted outdoors, above ground,

on an H‐frame, a wall, a concrete pad, a post, or a pole. Optional

mounting kits are available to support a round pole (from 8” to

20” in diameter) or a square pedestal or post (minimum 8”

wide). Concrete pad mounting is supported when used with the

optional Boxer battery box or skirt. All mounting hardware (not

provided) must be capable of supporting the weight of the Boxer

cabinet (approximately 70 pounds) plus the weight of any equip

ment mounted in it (up to 50 pounds). For convenience, lift

hooks or ears are provided. Run all cables to the mounting loca

tion, perform any trenching, trench cable placements, and

backfilling prior to the cabinet mounting, and clear the installa

tion area of any debris, vegetation, and unneeded equipment or

obstacles.

‐ KNOCK‐OUT REMOVAL NOTE ‐

Always remove knock‐outs where holes are desired before

mounting cabinet or securing the battery box, regardless of the

knock‐out type and regardless of the order of the mounting steps.

All knock‐outs should be knocked out from the inside of the

cabinet, except for the small 0.58” knock‐outs,which are to be

knocked out from the outside of the cabinet.

‐ WEIGHT NOTE ‐

The Boxer cabinet weighs 70 pounds. The weight of the internal

equipment installed in the Boxer should not exceed 50 pounds.

The mounting surface, structure, and hardware must be able to

support the combined weight (120 pounds).

3.6.1 Mounting on an H‐Frame

Follow company practice or the steps below to mount the Boxer

cabinet on an H‐frame. See Figure 12 for an H‐frame mounting

drawing. If the installation includes the battery box, attach the

battery box and the H‐Frame mounting kit to the cabinet prior

to mounting to the H‐Frame.

1. Determine exact mounting location in H‐frame. Select and

mark the exact horizontal and vertical final mounting loca

tion within the H‐frame. The spacing between the top and

bottom horizontal‐rail mounting holes should be 25.2”.

Westell recommends a height of 30” from the ground. In

addition to leaving a comfortable installer working height,

leave adequate space under Boxer for cable access (or an op

tional battery box), as stated in Paragraph 3.3, as well as in

front of the Boxer to allow the door to open (see Figure 26),

and at the sides in the event of any multiple installations.

2. Remove knock‐outs. See the steps in Paragraph 3.5 (Re

moving the Knock‐outs) to remove the knock‐outs where

any cable access holes (or holes for mounting the optional

battery box) are desired.

3. Prepare the mounting hardware. Bring the appropriate

mounting hardware to the installation site. The hardware

must be able to support the weight of the cabinet plus the

weight of any internal equipment to be installed. Insert at

least three rail nuts into each rail (compress the spring on

the nuts as needed) and slide them over to the desired

mounting location.

4. Lift cabinet. Lift the cabinet to the mounting height. If us

ing lift equipment, use two cables or straps of equal length,

one connected to each lift ear, for a balanced symmetrical

lift. The lift ears are provided at the top of the cabinet, one

at each side wall, and each lift ear has a 2” hole in it.

5. Attach cabinet to H‐frame rails. Align the holes in the cabi

net's top mounting bracket with the holes in the inserted

rail nuts in the H‐frame rails, then insert and install an ap

propriate bolt through each set of aligned holes. Westell

recommends a minimum of 3 mounting bolts per mount

ing flange (top and bottom). Tighten hardware appro‐

priately. Repeat for the bottom mounting bracket and H‐

frame rail. Verify the cabinet is in the proper horizontal

position, make any needed adjustments, then securely

tighten all mounting hardware.

6. Test installation firmness. Test the installation by attempt

ing to move the cabinet. Correct any looseness, if detected.

Tighten all bolts again.

7. Determine next step. If ground, power, and communica

tions cables and internal equipment will not be connected

and mounted at this time, proceed to the next step to final

ize the cabinet installation. If ground, power, and

communications cables and internal equipment will be

connected, mounted, and powered‐up at this time, skip

the next step and proceed to Paragraphs 3.7 through Para

graph 3.16 for those procedures.

8. Close up cabinet and clean the site. Close the Boxer door,

and lock it using a can wrench or 216 tool and an optional

padlock. Pick up any tools and materials at the installation

site, and clean the site of any trash or debris.

3.6.2 Mounting on a Wall

Follow company practices or the steps below to mount the Box

er cabinet to an approved wall (Figure 13). The approved wall

and hardware used must be able to support the combined

weight of the cabinet, the equipment mounted inside the cabi

net, plus the optional battery box (and batteries), if installed.

Westell recommends a minimum cabinet installation height of

30” from the ground. See Figure 11 for cabinet and mounting

hole dimensions.

1. Find best wall position. Locate the best mounting position

for the cabinet on the wall. Verify this location meets all cabi

net spacing requirements and company practices.

2. Remove knock‐outs. See Paragraph 3.5 (Removing the

Knock‐outs) to remove the knock‐outs where any cable ac

cess holes are desired.

3. Prepare the mounting hardware. Bring the appropriate

4. Determine mounting height and mark top hole locations.

Measure and mark the top mounting hole locations on the

wall, in a straight level line. This can be done by lifting and

leveling the cabinet then marking the mounting hole loca

tions, or without lifting and using the equipment as a

template. The horizontal distance between the holes in

the mounting flanges is shown in Figure 11. Two of the

holes are 16” apart on centers, to facilitate mounting on

standard walls with studs 16” apart on centers. The vertical

distance between the holes in the top and bottom mount

ing flanges is 25.2”. Westell recommends a minimum of 3

mounting bolts in each mounting flange. In addition to al

lowing for a comfortable installer working height (leave

about 30” under the cabinet), leave adequate space under

Boxer for cable access (or an optional battery box), as

stated in Paragraph 3.3, as well as in front of the mounting

to allow the door to open and at the sides in the event of

any multiple installations. With a marking utensil, mark

the top mounting holes to be drilled, in a level horizontal

line, at the desired wall height.

5. Drill top mounting holes. Drill appropriately‐sized pilot

holes, slightly smaller than the width and depth of the mount

ing bolts, screws or fasteners, at the marked locations. Do not

drill the holes too large.

6. Partially install bolts. Partially install the bolts until only 1/2”

remains.

7. Lift cabinet, and align mounting holes. Lift the cabinet to

the protruding bolts, align the top mounting flange keyholes

with the bolts, then hang the cabinet from the bolts. If using

lift equipment, use two cables or straps of equal length, one

connected to each lift ear, for a balanced symmetrical lift.

The lift ears are provided at the top of the cabinet, one at

each side wall, and each lift ear has a 2” hole in it.

8. Fully install the top mounting bolts. Verify the cabinet is

level. Finish driving the top mounting bolts until they are

snug and the cabinet is flush and tight against the wall.

Manually test the bolt tightness to verify the bolts will sup

port the cabinet weight before the next step. Correct any

level or mounting bolt discrepancies.

9. Mark and drill bottom mounting holes. Mark the exact

locations for the bottom bracket's mounting bolts through

the predrilled slotted holes in the bottom mounting brack

et. Drill appropriately‐sized pilot holes, slightly smaller

than the width and depth of the bolts, at the marked loca

tions. Do not drill the holes too large.

10. Install bottom mounting bolts. Insert and drive all bottom

bolts completely in to their final seated position. Finish the

installation by verifying all bolts are firm and snug.

11. Determine next step, or close up cabinet and clean the site.

Repeat Steps 6‐8 of Paragraph 3.6.1 to determine the next

step or finish the physical cabinet installation.

3.6.3 Mounting on a Pole or Post
