2. FEATURES
This section describes the exterior and interior features of the
WestellrBoxertoutdoor cabinet in more detail. Refer to
Figure 2 through Figure 13 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
Boxer‐30 is designed to be weather‐tight for above‐ground install
ation. The powder‐coat painted aluminum 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. Security is provided via a 3‐point
latch, a cup‐washer screw, and a padlock hasp. Side‐wall lift
ears (Paragraph 2.1.2.5) are provided for temporary installa
tion lift‐assistance. Two full‐width mounting brackets at the top
and bottom of the cabinet facilitate wall and H‐frame mount
ing. The bottom floor of the main cabinet contains numerous,
differently‐sized, intact knock‐outs (Paragraph 2.1.2.6) to ac
commodate a variety of cable, fitting, or conduit sizes or types.

Note: When closing and locking the door,
the door must be pushed fully closed be
fore actuating the swing handle, or dam
age to the locking mechanism may result.
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 43.2” (as shown in Figure 3). The cabinet's cool
ing system is a heat exchanger mounted to the door. At the inside
bottom of the door is a wind‐latch, shown in Figure 2, which 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 (105 degrees). In the closed position, the inside
perimeter of the door abuts 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 3‐point latching door handle is a padlock hasp
and a tamper‐proof hex nut‐in‐cup‐washer screw for locking
the door. The cup‐washer screw (Figure 4) is loosened and

tion to providing security, when fully‐tightened, this cup‐
washer screw helps to seal the cabinet and protect the interior
environment from outside elements or contaminants by com
pressing the door and panel against their gasket(s). Additional
security is offered for the door via a hasp in the handle that ac
cepts a field‐provided lock or padlock. Once the locks are open,
lift the bottom of the handle and rotate the handle counter‐
clockwise to release the 3‐point latch. When closing and locking
the door, the door must be pushed fully closed before actuating the
swing handle, or damage to the locking mechanism may result.
2.1.2.3 Rear‐Access Panel (Detachable)
The rear‐access panel (Figure 6) can be removed for conve
nient access to the rear of equipment mounted inside Boxer‐30.
The purpose of the access panel is to facilitate equipment ac
cess, cabling, and servicing. The panel is secured with 7/16” hex
nut‐in‐cup washer screws and can be removed with a 216 tool
or can wrench. With the panel removed, the access hole mea
sures approximately 19.25” wide by 48.75” high (see Figure 5).
2.1.2.4 Top/Bottom Mounting Brackets
Two full‐width, heavy‐duty, mounting brackets, one at the top
and one at the bottom of the cabinet, come factory‐installed.

2.2.4 Cooling System / Heat Exchanger
2.2.4.1 The Boxer‐30 cabinet features an active heat‐ex
change system that compensates for the effects of internal
equipment heat and external solar and temperature loading in
side the cabinet. At the core of the heat exchange system are
numerous aluminum fins on each “side” of a sealed divider wall
within the heat exchanger. The dual air‐path exchanger uses
one fan 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

ÖÖ
second fan 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.
2.2.4.2 The internal and external fans of the heat exchanger
are thermostat controlled. The internal heat exchanger fan will
turn on at 10% speed when the internal temperature reaches
70_F (21.1_C) and will reach full speed when the internal tem
perature reaches 80_F (26.7_C). The external heat exchanger
fan will turn on at 10% speed when the external temperature
reaches 90_F (32.2_C) and will reach full speed when the intern
al temperature reaches 100_F (37.7_C). Each fan will turn off
when the temperature drops 5_F (3_C) below it on temperature.
2.2.5 AC Duplex & GFI Outlets for Installed Equipment
In the bottom‐right rear corner of the cabinet are two AC du
plex outlets (with a 1/2” fitting below one on the cabinet
exterior surface), for powering any customer‐supplied AC‐
powered equipment mounted in the cabinet. When an external
AC power source is connected to these outlets, AC power also
can be provided to the GFI convenience outlet in the lower‐left
front corner of the cabinet (to facilitate the installer's test
equipment powering), by installing the provided AC 3‐wire
cable.
2.2.6 Grounding and Bonding Center
Boxer‐30's grounding and bonding center is located on the bot
tom interior surface of the cabinet (Figure 13), close to the
front door. A ground plate is provided that contains eight sets
of ground posts and one copper ground lug, for cable and chas
sis/earth ground. Bond equipment/cables to the ground posts
per company practice, and connect a #6 AWG chassis or earth
ground wire to the ground lug. An Electro‐Static Discharge
(ESD) wrist‐strap jack is also located on the ground plate.

3.5 Removing the Knock‐outs
Knock‐outs should be removed prior to mounting the cabinet.
Do not remove knock‐outs if they will not be used. See Figure 9
or Table 1 for knock‐out sizes, quantities, and locations, and fol
low the steps below to remove the knock‐outs.
1. Open the cabinet door. If knock‐outs will need to be re
moved, using a 216 tool or can wrench, open the large front
door of the Boxer‐30 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‐30 cabinet is typically mounted outdoors, above
ground, on a concrete pad. Top and bottom mounting brackets
facilitate wall or H‐frame mounting. Concrete pad mounting is
typically used 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 hard
ware (not provided) must be capable of supporting the weight
of the Boxer‐30 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). Always use ap
propriate life equipment. Run all cables to the mounting
location, 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 0.575” knock‐outs, which are to be
knocked out from the outside of the cabinet.
3.6.1 Mounting on a Concrete Pad
The Boxer‐30 cabinet can be mounted on a concrete pad, typi
cally with an optional Boxer battery box (and “side car”). When
mounting with a battery box, remove the five small knock‐outs
on the bottom of the Boxer‐30 cabinet which match holes in the
top surface of the battery box. To facilitate the concrete anchor
bolt placement, order and use the optional A90‐BXA19‐PT1
pad mount kit (listed in Table 2) for complete details on pad‐
mounting the Boxer‐30 cabinet. The mounting surface and hard
ware used must be able to support the combined weight of the cabinet
and the equipment mounted inside the cabinet. Always use appro
priate lift equipment.
3.6.2 Mounting on an H‐Frame
To mount the Boxer‐30 on an H‐frame, follow company prac
tice or the steps below. See Figure 14 for an H‐frame mounting
illustration. The approved mounting surface, framework and hard
ware used must be able to support the combined weight of the cabinet
and the equipment mounted inside the cabinet. Use appropriate lift
equipment.
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 62.6”
(on centers). Westell recommends leaving a comfortable
installer working height, leave adequate space under Box
er‐30 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. If not removed already, see the steps
in Paragraph 3.5 (Removing 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‐30, remove the small knock‐outs on the Boxer‐30's
right side wall to accommodate the side car's mounting
bolts and any cable knock‐outs.
3. Prepare the H‐frame mounting hardware (insert rail
nuts). Bring the appropriate rail nuts (to secure the cabi
net to the H‐frame) to the installation site. All 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 mount
ing hole 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 to ac
cept large straps or hoisting cables. Do not use the lift ears
for permanent mounting.

propriate H‐frame mounting bolt through each set of
aligned holes. Westell recommends a minimum of 3
mounting bolts per mounting bracket (top and bottom).
Tighten hardware appropriately. Repeat for the bottom
mounting bracket and H‐frame rail. Verify the cabinet is
in the proper horizontal position, make any needed ad
justments, 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‐30
door, and lock it using a can wrench or 216 tool and an op
tional padlock. Pick up any tools and materials at the
installation site, and clean the site of any trash or debris.

3.6.3 Wall Mounting
Follow company practices or the steps below to mount the Box
er‐30 cabinet to a wall. The approved mounting surface,
framework and hardware used must be able to support the combined
weight of the cabinet and the equipment mounted inside the cabinet.
Use appropriate lift equipment.
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. If not already removed, see the steps
in Paragraph 3.5 (Removing 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‐30, remove the small knock‐outs on the Boxer‐30's
right side wall to accommodate the side car's mounting
bolts and any cable knock‐outs.
3. Locate the mounting hardware. Bring the appropriate
wall‐mounting hardware to the installation site. The hard
ware must be able to support the weight of the cabinet plus
the weight of the added internal equipment. Use a mini
mum of 10 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 by measuring (without lifting the equipment as a
template). Two of the mounting bracket holes are 16”
apart on centers, to facilitate mounting on standard walls
with studs 16” apart on centers. The vertical distance be
tween the holes in the installed top and bottom mounting
brackets (when attached to the cabinet) is 62.6”. Westell
recommends using 5 mounting bolts in each mounting
bracket. In addition to allowing for a comfortable installer
working height, leave adequate space under Boxer‐30 for
cable access, 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 lev
el 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. Using appropriate
lift equipment, lift the cabinet to the protruding bolts,
align the top mounting bracket's keyholes with the bolts,
then hang the cabinet from the bolts. If using lift equip
ment, 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. Never
release the cabinet from the lift equipment until the in
stallation is complete and determined to be safe.
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.
