2. FEATURES
This section describes the exterior and interior features of the
Westell Boxerroutdoor 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 tamper‐proof screw‐lock, 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 (Paragraph 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 lock. The lock (Figure 4) is loosened and tight
ened with a can wrench or 216 tool (for the ‐7HE model) or a
pin‐in‐hex wrench (for the ‐7HEG model, wrench provided). In
addition to providing security, when fully‐tightened, this lock
helps to seal the cabinet and protect the interior environment
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 bottom 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
tamper‐proof screws (hex‐nut‐in‐cup type for the ‐7HE model
and pin‐in‐hex type for the ‐7HEG model). The panel can be
removed with a either a 216 tool or can wrench (for the ‐7HE
model) or with a special hex wrench (provided with the ‐7HEG
model). 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,

2.1.2.6 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‐16 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‐16 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.
2.1.2.7 AC Conduit Fitting
A ½” AC conduit fitting is provided on the exterior bottom sur
face of the cabinet (see Figure 8) through a knock‐out hole near
the back right corner, to facilitate conduit attachment. Inside the
cabinet, the fitting is connected to an AC outlet box immediately
above it inside the cabinet.

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.
‐ 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.
2.2.2 Door Sensor Switch
A door sensor switch is located at the bottom right corner of the
cabinet door opening (Figure 11). 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 / Heat Exchanger
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 two
heat exchanger fans (see location in Figure 12) are temperat
Figure 11. Door Sensor Switch Location
Door Switch
(prewired to
controller card)
ure 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 ex
change system are numerous aluminum fins (visible through the
compartment's vent holes) on each “side” of a sealed divider
wall within the heat exchanger. The dual air‐path exchanger uses
the lower‐mounted fan to blow cool outside air past the “exterior
air side” fins of the heat exchanger and to direct the heated air
out the vent holes on the sides of the fan cover. Conversely, the
upper‐mounted fan circulates warm inside air down past the “in
terior air side” fins of the heat exchanger and blows cooled air
into/through the main cabinet compartment. The heat ex
changer unit is field‐replaceable (see Table 4 for part number).
2.2.4 Heat Exchanger Fans (“FAN A” Connector)
Two, factory‐installed, temperature‐controlled fans (shown in
Figure 12) circulate air through the heat exchanger. One fan is
used for the external circuit, and one fan is used for the internal
circuit.
The internal fans perform as follows:
GOff at ‐40°C G50% on at 30°C G100% on at 45°C
The external fans perform as follows:
GOff at ‐30°C G50% on at 40°C G100% on at 55°C
Both of these fans are factory‐wired to the “FAN‐A” connector
on the controller card mounted on the left side wall of the cabi
net, and are powered from either a field‐provided +24VDC
power source or a ‐48VDC power source. The fans are not
field‐replaceable, and the heat exchanger housing the fans must
be replaced in the event of a unit failure (see Table 4).
2.2.5 Controller Card
Boxer‐16 includes a factory‐wired controller card located on the
inside left wall of the cabinet (Figure 13). The card includes con
nections for the fans, temperature alarm, door alarm, and a 3A
fan fuse. Internal wiring has been factory‐wired. External wiring
to the power source and alarm monitoring equipment is done us
ing “Euro‐connector” snap‐in terminal blocks which can be
disconnected from the controller card, and later re‐attached for
quick and easy connections. Table 2 lists all of the connectors
and positions on the controller card. The only installer connec
tions are the TEMP ALARM, DOOR ALARM, and ‐48V and
GND for power connections. To make these connections to the

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 or the provided
pin‐in‐hex wrench, open the large front door of the Box
er‐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
provided) must be capable of supporting the weight of the Box
er‐16 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 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
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

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

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

Section BXM‐161‐7HE‐20A 030‐101765 Rev. B R
16 1311IARB
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
card. Re‐insert all connectors in their proper positions in
the card, connecting the power connector block last.
5. Test . Verify the alarms and fans work.
‐ CAUTION ‐
To avoid electrical shock, turn off any DC or AC power feeds
to the controller before beginning this procedure.
5.2 Replacing the Heat Exchanger
The single‐unit fans/heat exchanger cannot be field repaired.
Should a problem be suspected with the heat exchanger or fan
within it, the entire heat exchanger unit must be removed and
returned to Westell for service, then re‐installed or replaced.
Follow the steps below to replace the controller card.
1. Open the cabinet. Open the cabinet door by loosening the
door lock with a can wrench or 216 tool (for the ‐7HE mod
el) or with the special provided pin‐in‐hex wrench (for the
‐7HEG model), then turning the door handle (see Figure 4).
2. Remove fuse. Remove the 3A fan fuse from the controller
card (see Figure 13 or Figure 20 for fuse location).
3. Disconnect fan power. Disconnect the FAN A Euro con
nector at the controller card and remove the two wires
from the connector. Note which colored wires were re
moved from which connector terminals. Replace the Euro
connector back into the card.
4. Free the power cables. Remove or disengage the power
cord from the cable management clips/clamps on the
door, and remove any cable ties.
5. Remove heat exchanger. Remove the heat exchanger unit's
mounting hardware (Allen screws) located on the inside of
the door, then firmly grasp and lift off the heat exchanger
compartment from the door. Make a written note of the
length of the old power cord.
‐ RETURN UNIT NOTE ‐
Return the old/defective unit to Westell, and receive a replace
ment/new unit (see Paragraph 7.2 for details).
6. Mount the replacement heat exchanger unit. Route the
power cord of the replacement heat exchanger through
the access/hole cut‐out near the top of the cabinet door,
then mount the new heat exchanger to the door using the
retained hardware from the step above. Firmly tighten the
hardware.
7. Prepare power cord/wires. Verify the length of the new
unit's power cord is sufficient to comfortably reach the
FAN A connector in the controller card on the left inside
wall of the cabinet, without tension, with the door in both
the open and closed positions. If needed, trim the new
power cord to length, using the old heat exchanger unit's
cord length as a reference (refer to the length recorded in
Step 5), or simply verify the cord can reach the controller
card with sufficient slack and without undue tension. Ex
pose the cord's black and white wires (trim/cut off approx.
1‐2” of the cord's thicker, black, outer jacket material),
then strip off approximately ½” of jacketing from the black
and white wires to expose the copper wires.
‐ FAN WIRING IN EURO‐CONNECTOR NOTE ‐
A Euro‐connector serves the cabinet fan (connector labeled
“FAN A”). The fan has a black wire and a red wire. When wiring
a new or replacement fan, the same colored wire from the fan
should first be twisted together as a single wire unit prior to
insertion into its proper termination hole in the connector.
8. Connect power cord wires to FAN A Euro connector. Re
move the FAN A Euro connector from the controller card.
(If not already removed, remove the old wires from the
connector by loosening the set screws in the connector.(
Verify the set screws in the Euro connector are loosened
enough to allow the new wires to be fully inserted and con
nected. Twist the stripped copper wire ends of the new
black and white jacketed power wires, then insert the wires
into their proper wire port holes (black wire goes to the
BLK wire port hole labelled “BLK” and the white wire
goes to the “RED” wire port hole). After the correct wires
are inserted into the correct holes, hold the wires in place
and firmly tighten the set screws. To test the connection,
attempt to pull the wire out from the hole; correct any
loose connection. Re‐install the connector into the card.
9. Re‐install the fuse. Install the 3A fuse that was removed in
Step 2 back into its place in the controller card.
10. Perform cable management. Manage any cable slack and
secure the power cord by using the clamps and clips on the
inside walls and door of the cabinet and using cable ties per
company practice. Verify all wires are clear of the door
hinges and flanges and will not be pinched.
11. 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.
