2. FEATURES

This section describes the exterior and interior features of the

WestellrBoxerroutdoor cabinet in more detail. Refer to

Figure 2 through Figure 10 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‐20 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 2‐point latch, a tamper‐proof screw lock and a padlock

hasp. Side‐wall lift ears (Paragraph 2.1.2.6) are provided for

temporary installation lift‐assistance. 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 clearance or distance from

the back of the cabinet to the outer edge of the open door is

approximately 43.5” (as shown in Figure 3). The cabinet's cool

ing system is based in the door, with screened holes, a heat

exchanger and fans mounted in the door. At the inside bottom

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

tects the door (and technician) from possible wind damage. The

wind latch restricts the door's swing‐out angle to a safe but func

tional opening (95 degrees). In the closed position, the inside

perimeter of the door mates with a gasket installed around the

outer perimeter of the cabinet's door opening. When the door

is closed and tightened, the door and gasket provide a weather‐

tight seal to protect all equipment installed inside the cabinet.

The door sensor is described in Paragraph 2.2.2.

2.1.2.2 Door Handle, Door Locks and Panel Lock(s)

Built into the 2‐point latching door handle is a padlock hasp and

a tamper‐proof lock. The lock (Figure 4) is loosened and tight

ened with a can wrench or 216 tool (for the ‐4HE3 model) or a

pin‐in‐hex wrench (for the ‐4HE3G model, wrench provided). In

addition to providing security, when fully‐tightened, this cup‐

screw lock helps to seal the cabinet and protect the interior envi

ronment from outside elements or contaminants by

compressing the door and panel against their gasket(s). Addi

tional security is offered for the door via a hasp in the handle that

accepts a field‐provided lock or padlock. Once the locks are

open, lift the bottom of the handle and rotate the handle count

er‐clockwise to release the 2‐point latch. When closing and

locking the door, the door must be pushed fully closed before actuat

ing the swing handle, or damage to the locking mechanism may

result.

2.1.2.3 Heat Exchanger Compartment

The cabinet's cooling system is based in the door, in a heat ex

changer compartment (see Figure 5). The compartment has a

secure cover, vents, a heat exchanger, and fans. To access the

heat exchanger compartment, loosen the Phillips screw that se

cures it, located near the center inside surface of the door

(under the internal fans, shown in Figure 6), then lift the com

partment cover up off the cover‐alignment posts at the top of

the compartment (see Figure 5).

2.1.2.4 Rear‐Access Panel (Detachable)

The rear‐access panel (Figure 7) can be removed for conve

nient access to the rear of equipment mounted inside Boxer‐20.

The purpose of the access panel is to facilitate equipment ac

cess, cabling, and servicing. The panel is secured with ten

tamper‐proof screws (hex‐nut‐in‐cup type for the ‐4HE3 mod

el and pin‐in‐hex type for the ‐4HE3G model). The panel can

be removed with a either a 216 tool or can wrench (for the

‐4HE3 model) or with a special hex wrench (provided with the

‐4HE3G model). With the panel removed, the access hole mea

sures approximately 17” wide by 23.5” high (see Figure 6).

2.1.2.5 Mounting Brackets

Full‐width mounting brackets are attached at the back of the

Boxer‐20 cabinet, one at the top and one at the bottom. The top

bracket has seven mounting holes in it (two of which are spaced

16” apart for stud wall mounting) and the bottom bracket has

five slots, for easy slide‐in installation. Use approved wall‐

mounting fasteners with a diameter of up to 3/8”. The vertical

equipment to be mounted in it.

2.1.2.6 Side Lift Ears

The Boxer‐20 cabinet is equipped with two removable external

lift ears or brackets, one on each side, attached at the top of the

cabinet (see Figure 3). These lift ears can be used to lift the cabi

net using lift equipment, 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. Remove the

ears if mounting with a Boxer side car (use the same hardware).

Do not use these lift ears for permanent mounting.

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‐20 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‐most three

are typically for customer cable access, and the rear‐most knock‐

outs are typically for Network cable access. The knock‐out sizes

and quantities are shown in Table 1 and Figure 9. A “concentric”

knock‐out is provided for both Customer and Network access:

depending upon which direction the knock‐out is removed, ei

ther a 1/2” or 3/4” hole will be produced. Do not remove a

knock‐out unless it is absolutely necessary to do so for cable in

gress 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‐20 cabinet where an option

al 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.

cable access. The fitting is connected to an AC outlet box imme

diately above it inside the cabinet.

2.2 Interior Features

The interior cabinet features are described hereunder.

2.2.1 Internal 19” Rack Channels

Two removable/adjustable rack channels inside the cabinet pro

vide 20‐RU‐high 19” relay rack mounting for equipment that is

to be mounted in the cabinet. Each adjustable channel is factory‐

installed so approximately 5” of equipment space is available

from the inside of the closed front door to the channel (for up

to a 5” equipment projection), and approximately 12” of equip

ment space is available behind the channel to the rear cabinet

wall. The channels can be moved forward or backward the entire

depth of the cabinet, as needed, if more equipment depth is

needed at either the front or back of the channel. Multiple holes

are provided for multiple channel positions. Each rack channel

has predrilled holes, with standard hole spacings (either 1”,

1.75”, or 2” rack hole patterns), to mount customer‐supplied

equipment in the cabinet. Network equipment up to 20 Rack

Units (20 RUs = 35”) high can be mounted on the internal rack

inside the cabinet, either as a single piece or multiple pieces of

equipment.

most channel mounting positions is chosen for the left channel.

2.2.2 Door Sensor Switch

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

cabinet door opening (Figure 10). This switch is factory‐pre

wired 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.

2.2.3 Cooling System

The Boxer‐20 cabinet features an active heat‐exchange system

that compensates for the effects of internal equipment heat and

external 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 11) 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 10) 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 Internal‐Air Fans (“FAN B” Connector)

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

Figure 10) 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.

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

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

Figure 11) 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.

2.2.6 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, tem

perature, and alarm wiring and connections) to the controller

card.

Boxer‐20 includes a factory‐wired controller card located on

the inside left wall of the cabinet (Figure 12). The card includes

connections 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‐connec

tor” snap‐in terminal blocks which can be disconnected from the

controller card, and later re‐inserted for quick and easy connec

tions. 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

wrench, to minimize possible product damage and person

al injury.

3.6 Mounting the Cabinet

The Boxer‐20 cabinet is typically mounted outdoors, above

ground, on an H‐frame, a wall, a concrete pad, or a pole. Option

al mounting kits are available to support pole (from 8” to 20” in

diameter), wall, and H‐frame mounting. Concrete pad mount

ing is typically performed in conjunction with the optional Boxer

battery box. An optional pad mount template kit is available for

easy and convenient cement anchor placement. All mounting

hardware (not provided) must be capable of supporting the

weight of the Boxer‐20 cabinet plus the weight of any equipment

mounted in it. For convenience, lift hooks or ears are provided

for temporary lifting purposes (do not use lift ears from which

to hang the cabinet in permanent installations). Run all cables

to the mounting location, perform any trenching, trench cable

placements, and backfilling prior to the cabinet mounting, and

clear the installation area of any debris, vegetation, and unneed

ed 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 0.575” knock‐outs (which are to be

knocked out from the outside of the cabinet) and except for the

‐ WEIGHT NOTE ‐

The Boxer‐20 cabinet weighs 110 pounds. The weight of the inter

nal equipment installed in the Boxer‐20 should not exceed 130

pounds. The mounting surface, structure, and hardware must be

able to support the combined weight (240 pounds).

3.6.1 Mounting on an H‐Frame

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

er‐20 cabinet on an H‐frame. See Figure 15 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 cabi

net 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 H‐frame horizontal‐rail mounting holes should be

42.7” (on centers). Westell recommends a height of 30”

from the ground. In addition to leaving a comfortable in

staller working height, leave adequate space under

Boxer‐20 for cable access, as well as in front of the cabinet

to allow the door to open, 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. Note that if a Boxer “Side Car”

cabinet is being installed with the Boxer‐20, remove the

small, blind, threaded receptacles on the Boxer‐20's right

side wall to accommodate the side car's mounting bolts..

3. Prepare the H‐frame mounting hardware. Bring the ap

propriate rail nuts (to secure the cabinet to the H‐frame)

to the installation site. The mounting hardware must be

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

the added internal equipment. Insert at least three rail

nuts into each rail (compress the spring on the nuts as

needed) and place them at the desired locations.

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‐20

door, and lock it using a can wrench or 216 tool (‐4HE3)

or the provided pin‐in‐hex wrench (‐4HE3G) and an op

tional 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‐20 cabinet to an approved wall (Figure 16). The approved

wall and hardware used must be able to support the combined

weight of the cabinet and the equipment mounted inside the

cabinet. Westell recommends a minimum cabinet installation

height of 30” from the ground.

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

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

cabinet spacing requirements and company practices.

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. Note th at if a Boxer Side Car also

will be mounted with the Boxer‐20 cabinet, the knock‐outs

on the right side wall of the Boxer‐20 should be removed,

as well.

3. Prepare the mounting hardware. Bring the appropriate

wall‐mounting hardware to the installation site. The hard

ware must be capable of supporting the weight of the

cabinet plus the weight of the added internal equipment.

Use a minimum of 6 mounting fasteners (such as lag bolts).

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 inside keyholes ae 4” apart on centers, and

two of the holes are 16” apart on centers, to facilitate

mounting on standard walls with studs 16” apart on cen

ters. The vertical distance between the holes in the

installed top and bottom mounting brackets (when at

tached to the cabinet) is 43.7”. Westell recommends a

minimum of 3 mounting bolts in each mounting bracket.

In addition to allowing for a comfortable installer working

height (leave about 30” under the cabinet), leave adequate

space under Boxer‐20 for cable access, as stated in Para

graph 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 mount

ing 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

mounting bolts, screws or fasteners, at the marked loca

tions. 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 bracket's key

holes 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 sym

metrical 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. Drill bottom mounting holes. Drill appropriately‐sized pi

lot holes, slightly smaller than the width and depth of the

bolts, for the lower mounting bracket. Use a minimum of

three bolts. 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

Order the optional A90‐BXA‐PM02 pole mount kit (shown in

Figure 17 and listed in Table 4) for details and instructions on

pole‐mounting the Boxer‐20 cabinet. See Figure 18 for a brief

installation procedure.

3.6.4 Mounting on a Concrete Pad

The Boxer‐20 cabinet can be mounted on a concrete pad, typi

cally with an optional Boxer battery box (and “side car”). To

facilitate the concrete anchor bolt placement, order and use the

optional A90‐BXA19‐PT1 pad mount kit (listed in Table 4) for

details on pad‐mounting the Boxer‐20 cabinet.

3. Pre‐thread inner nuts for rear

brackets. Thread a nut and washer

onto the long end of each rod; stop threading when the nut appears to be

about 1/4 of the distance into the pole depth (from the rear).

4. Lift, level, and secure cabinet to pole. Lift the cabinet to the desired

mounting height, straddle the pole with the protruding rods, press the cabi

net and the serrated edge of the attached brackets against the pole, and lev

el the cabinet. Hold the cabinet in place, and from behind the cabinet and

pole, hang another kit bracket from the top protruding rods, being careful to

select and align the holes correctly (select the same holes that were used

for the bracket attached to the cabinet) and also being sure to face the ser

rated edge of the kit's bracket toward the pole. Thread a washer, lock wash

er, and a nut onto each rod and alternately tighten each rod's nut firmly

against the bracket (so the lengths of the two rods left protruding are equal).

When tight, back‐thread the nuts previously threaded onto the rod (from

Step 3 above) backwards to abut the inside edge of the kit's rear mounting

bracket.

5. Repeat above step for the lower, rear,

power dissipation reduces the likelihood of condensation within

the cabinet. However, follow company practices for desiccant

maintenance procedures to prevent internal condensation.

‐ 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.

3.12 Mounting Equipment Inside Boxer‐20

Boxer‐20 utilizes a 20‐RU high and 19” wide rack with adjust

able/removable rack channels. Multiple threaded holes are

provided on the inside walls (best shown in Figure 7) which al

low the channels to be mounted in multiple positions (can be

adjusted forward or backward as needed to support Network

equipment). Boxer‐20's rack‐hole pattern accommodates a

wide variety of equipment and mounting bracket hole patterns.

Always follow company practices and the guidelines below when

mounting equipment inside the cabinet.

1. Verify the combined equipment height does not exceed 20

RUs.

2. Verify the combined weight of all customer‐supplied

equipment installed inside Boxer‐20 does not exceed 130

pounds.

3. Verify any equipment to be installed in the cabinet will not

extend into or past the fan guards or grills on the door of

the cabinet. Slightly deeper equipment can be mounted in

the lower positions of the channels (below the fans).

4. Verify each piece of equipment does not exceed the cabi

net's interior width or depth.

5. Determine the best mounting location for each piece of

equipment, for maximum capacity.

6. Verify the combined wattage of all equipment installed in

the cabinet does not exceed 400 watts.

7. Determine/adjust the rack channel depth (optional). The

channels are factory installed for 5” of clearance in front

of the rack and 12” of clearance behind the rack. If a differ

ent clearance is required, remove the bolts from each

channel (best shown in Figure 7), position the channels as

needed, and re‐install the bolts into each rack channel.

8. Use the bond posts provided on the ground plate as need

ed for bonding or grounding any cables or equipment

installed inside the cabinet.

3.13 Using the Rear Access Panel

As stated in Paragraph 2.1.2.4 and as shown in Figure 6 and

Figure 7, Boxer‐20 contains an access panel on the rear wall to

facilitate making cable connections at the inside rear of the cabi

net. The panel is secured with cup‐washer screws (‐4HE3) or

pin‐in‐hex screws (‐4HE3G, pin‐in‐hex wrench provided).

3.14 Connecting Communication Cables

The types of communication cables used and their connector

types (if any) vary per the application and the equipment

installed inside the cabinet. To accommodate a variety of cable

and connector sizes, the Boxer‐20 cabinet has cable‐hole

knock‐outs of various sizes, as shown in Table 1 and Figure 9.

1. Run the communications cables to the Boxer‐20 cabinet.

2. Insert and route the cable through the desired grommet.

Section BXM‐204‐HE3‐20A

1311IARB

3. Attach the cable's connector to the appropriate connector

of the targeted equipment.

4. Repeat for each cable.

5. Make any desired connections between pieces of equipment.

6. Use the bond posts and ground lugs provided on the ground

plate as needed for bonding and grounding any commu

nications cables brought into the Boxer‐20 cabinet.

3.15 Making TEMP/DOOR ALARM Connections

The high temperature alarm and door alarm connections are

located on the Controller Card located on the inside left wall

of the cabinet. Easy pull‐off/push‐on Euro‐connectors are pro

vided for these installer connections. To make connections to

the Euro‐connectors, pull‐off the Euro‐connector, strip ¼” off

the end of each wire to be connected, insert the wire into the

provided hole, tighten the set screw to secure the wire, repeat

for each wire, then push‐on the Euro‐connector.
