2. FEATURES
This section describes the exterior and interior features of the
WestellrBoxertoutdoor cabinet in more detail. Refer to
Figure 2 through Figure 11 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‐16 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 cup‐washer screw and a padlock hasp. Side‐

wall lift ears (Paragraph 2.1.2.5) are provided for temporary
installation lift‐assistance. The bottom floor of the main cabinet
contains numerous, differently‐sized, intact knock‐outs (Para
graph 2.1.2.6) 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 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 2‐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 2) is loosened and tight
ened with a standard telco can wrench or 216 tool. In addition
to providing security, when fully‐tightened, this cup‐ washer
screw helps to seal the cabinet and protect the interior environ
ment from outside elements or contaminants by compressing
the door and panel against their gasket(s). Additional 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 bot
tom of the handle and rotate the handle counter‐clockwise to
release the 2‐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‐16.

The purpose of the access panel is to facilitate equipment ac
cess, cabling, and servicing. The panel is secured with six
hex‐nut‐in‐cup screws and can be removed with a 216 tool or
can wrench. With the panel removed, the access hole measures
approximately 25” high by 19.25” wide (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.
These brackets are typically used to mount the cabinet to a wall
or H‐frame. The top bracket has 7 `keyholes', and the bottom
bracket has 5 mounting `slots'. Use wall‐mounting fasteners with
a diameter of up to 3/8”. The vertical distance between the top
and bottom bracket holes is 39” (between the hole centers). The
mounting hardware and the mounting surface must be of sufficient
strength, quality and size to support the cabinet plus all equipment
to be mounted in it.
2.1.2.5 Side Lift Ears
The Boxer‐16 cabinet is equipped with two 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 cabinet 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,

2.2.1 Internal 19” Rack Channels
Two adjustable rack channels (see Figure 10) inside the cabinet
provide 16‐RU‐high 19” relay rack mounting for equipment that
is to be mounted in the cabinet. Each adjustable channel is facto
ry‐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 2” or backward 3”, if
a few additional inches of equipment depth is needed at either
the front or back of the channel. The slotted mounting brackets
for each channel contain seven holes which allow six channel
positions. Each rack channel also contains predrilled holes, with
standard hole spacings (either 1”, 1.75”, or 2” rack hole pat
terns), to mount customer‐supplied equipment in the cabinet.
Network equipment up to 16 Rack Units (16 RUs = 28”) high
can be mounted on the internal rack inside the cabinet, either as
a single piece or multiple pieces of equipment.

2.2.3 Cooling System / Heat Exchanger
The Boxer‐16 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. 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 exchanger uses one
set of fans (shown in Figure 12) 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 11) 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, always‐on fans (see Figure 11) to circu
late 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, secured with Phillips screws, 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 a field‐provided
‐48VDC power source.
2.2.5 External‐Air Fans (“FAN A” Connector)
Two, factory‐installed, always‐on fans (shown in Figure 12) to
circulate cooler exterior air up through the heat exchanger are
located under the cover for the heat exchanger compartment.
These fans are factory‐wired to the “FAN‐A” connector on the
Controller Card mounted on the left side wall of the cabinet, and
are powered from a field‐provided ‐48VDC power source. To ac
cess or view the fans, loosen the Phillips‐head screw located just
under the two internal fans on the inside of the door, then from
the outside of the cabinet, lift off the external cover.

3.5 Removing the Knock‐outs
Knock‐outs should be removed prior to mounting the cabinet.
See Figure 9 or Table 1 for knock‐out sizes, quantities, and loca
tions, and follow 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‐16 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‐16 cabinet is typically mounted outdoors, above
ground, on an H‐frame, a wall, post, a concrete pad, or a pole.
An optional mounting kit is available to support pole mounting
(from 8” to 20” in diameter). Concrete pad mounting is typically
used when used with an optional Boxer battery box or skirt. An
optional pad mount template kit is available for easy and conve
nient cement anchor placement. All mounting hardware (not

For convenience, lift hooks or ears are provided for temporary
lifting purposes (do not use lift ears from which to hang the cabi
net 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 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) and except for the
concentric knock‐out (from either direction, per hole size).
‐ WEIGHT NOTE ‐
The Boxer‐16 cabinet weighs 80 pounds. The weight of the inter
nal equipment installed in the Boxer‐16 should not exceed 90
pounds. The mounting surface, structure, and hardware must be
able to support the combined weight (170 pounds).
3.6.1 Mounting on an H‐Frame
To mount the Boxer‐16 on an H‐frame, the top and bottom
mounting brackets are used. Follow company practice or the
steps below to mount the Boxer‐16 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 to the cabinet
prior to mounting the conjoined units 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 39” (on

Section BXM‐161‐4HE‐20A 030‐101374 Rev. A R
10 1211IARA
centers). Westell recommends a height of 30” from the
ground. In addition to leaving a comfortable installer
working height, leave adequate space under Boxer‐16 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.
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 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‐16
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.
3.6.2 Mounting on a Wall
Follow company practices or the steps below to mount the Box
er‐16 cabinet to an approved wall. 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

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.
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. Two of the holes are 16” apart on centers, to fa
cilitate mounting on standard walls with studs 16” apart on
centers. The vertical distance between the hole centers in
the installed top and bottom mounting brackets (when at
tached to the cabinet) is 39”. 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‐16 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. 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,

Periodically
3.17 Performing Cabinet Housekeeping
Verify all equipment is secure, verify all wires and cables are
neatly organized and managed, verify all bonding and ground
ing connections are made at the ground plate, and verify no
equipment, tie‐downs, cables, or wires will interfere with the
closing of the door. Clean up the installation site per company
practice.
3.18 Closing and Locking the Cabinet
Upon completion, the installer should close and lock the cabi
net by firmly pressing on the door, turning the swing handle to
the vertical position, then pressing the handle down to seat it.
When closing and locking the door, the door must be pushed fully
closed before engaging the swing handle, or damage to the locking
mechanism may result. Secure the door by tightening the cup‐
washer screw with a can wrench or 216 tool, and optionally lock
the door via the hasp in the door handle which accepts a field‐
provided lock or padlock (customer supplied).
4. MAINTENANCE
The WestellrBoxertcomponents are maintenance‐free,
however, please note the following items.
SAt least once every six months, periodic inspections
should be performed on the Boxer‐16 cabinet to remove
any debris from the screened vents located on the front
door (Figure 22). This facilitates proper operation of the
cabinet and allows unobstructed air flow.
SAt least once every six months, the air filter mounted on
the inside of the front door should be cleaned (see
Figure 23). This facilitates proper operation of the cabi
net and allows unobstructed air flow.
5. SERVICE AND REPAIRS
Replacing parts is the only recommended type of field repair
for the WestellrBoxertcabinet. The list below contains the
only Boxer parts which may be ordered and field‐replaced (see
Part 6 for a telephone number, Table 4 for part numbers, and
Paragraph 7.2 for the return procedure). See Paragraph 5.1
through 5.4 for detailed steps to remove and replace these
parts.

‐ CAUTION ‐
To avoid electrical shock, turn off any DC or AC power feeds
to the panel before removing or replacing the controller card.
5.1 Replacing the Controller Card
The Controller Card cannot be field repaired. Should a prob
lem be suspected with the card, it must be removed and
returned to Westell for service, then re‐installed or replaced.
Follow the steps below to replace the controller card.
1. Disconnect power. Disconnect power to the card by remov
ing the power Euro‐connector block (labeled “‐48V” and
“GND”. Pull the connector toward the cabinet front.
2. Remove all connectors. Disconnect all other wire connec
tions in the card by simply pulling off each Euro‐connector
in the controller card (on the card's left and bottom edges,
see Figure 20) in similar fashion, and labelling each con
nector as it is removed, to facilitate re‐connection with the
replacement card. It is not necessary to remove any wires
from the connectors (unless a fan is suspected of being
faulty and is also being replaced).
3. Remove card. Remove the old card by unscrewing the
hardware that secures the card to the cabinet wall, then
pulling the card off the studs.
4. Install new card. Replace the old card with the new card,
ordered and received from Westell. Be sure the GMT fuse
faces left and that the card labelling is visible and not up
side‐down. Align the mounting holes in the card with the
posts on the cabinet wall, then tighten the hardware re
moved in the step above back onto the studs to secure the

onto their mounting studs and reverse the steps above, and
also read the note below to secure the fan(s) and make
wire connections. Re‐insert the connector back into the
controller card.
‐ FAN WIRING IN EURO‐CONNECTOR NOTE ‐
One euro‐connector serves two fans: there is one connector for
the two external air fans (connector labeled “FAN A”) and one
connector for the two internal air fans (“FAN B”). Each fan has
a black wire and a red wire. When wiring a new or replacement
fan, the same colored wire from each fan should first be twisted
together as a single wire unit prior to insertion into its proper
termination hole in the connector.
14. Apply power and test. If not already installed, re‐install the
fuse in the controller card, and apply power to the cabinet.
Verify the fans are working properly.
5.3 Replacing the “Inside Air” Fans
