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 cup‐washer screws. Mounting flanges (Paragraph 2.1.2.2) are
attached at the top and bottom of the back wall for permanent
mounting. The bottom floor of the cabinet contains numerous,
differently‐sized, intact knock‐outs (Paragraph 2.1.2.4) to ac
commodate 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. A full‐length hinge
supports the door in the open position. 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” (as shown in Figure 23). At the
inside bottom 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 (105 degrees).
When the door is closed, an automotive‐grade sealing gasket
installed around the interior perimeter of the cabinet door
provides a weather‐tight seal to protect all equipment installed
in the cabinet. Both hex cup‐washer screws (door locks, see
Figure 2) can be loosened or tightened with a standard telco
can wrench or 216 tool. Additional door security is offered via
holes in the door flanges which accept a field‐provided lock or
padlock. The door sensors are described in Paragraph 2.2.1.
2.1.2.2 Mounting Brackets
Full‐width 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 10.
The vertical distance between the top and bottom mounting
bracket hole centers is 25.2”.
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
vent holes, a heat exchanger, and fans. To access the heat ex
changer compartment, loosen the hex nut that secures it which
is located at the bottom, center, interior surface of the door
(shown in Figure 3), then lift up the compartment cover to
clear the cover‐alignment posts at the top of the compartment.

2.1.2.4 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 be
low 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 ones
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 6. Do
not remove a knock‐out unless it is absolutely necessary to do
so for cable ingress and egress, and use either tight‐fitting rub
ber 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 com
pany‐approved tools to remove knock‐outs.
Battery Box 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).

2.2 Interior Features
The interior cabinet features are described hereunder.
2.2.1 Door Sensor Switches
Two door sensor switches are located at the bottom right corner
of the cabinet door opening (Figure 7). The switches are fact
ory‐prewired to the Controller Card. The left door switch will
trigger a door open alarm when the door is opened. The right
door switch will turn off the fans when the door is opened. To
temporarily disable a sensor, pull out the cylindrical door
switch actuator until it clicks. To re‐activate a 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

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 slot
ted channel bracket allows both channels to be easily moved
forward 2” or backward 3”, if a few additional inches of equip
ment 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 ver
tical rack channels contain predrilled holes, with standard hole
spacings (either 1”, 1.75”, or 2” rack hole patterns), for mount
ing customer‐supplied equipment in the cabinet. Network
equipment up to 10 Rack Units (10 RUs = 17.5”) high can be
mounted on the rack inside the cabinet, either as a single piece
or as multiple pieces of equipment.
2.2.3 Cooling System
The Boxer 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 nu
merous aluminum fins (best seen in Figure 2) on each “side” of
a sealed divider wall within the heat exchanger. The dual air‐

test switch
path exchanger uses one set of fans (shown in Figure 5) to blow
cool outside air past the “exterior air side” fins of the heat ex
changer and to direct the heated air out the vent on the sides
of the fan cover. Conversely, a second set of fans (shown in
Figure 2 andFigure 7) 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 Paragraphs 5.2 and 5.3,
Figure 19, and Table 4 for part numbers).
2.2.4 External‐Air Fans (“FAN A” Connector)
Two, factory‐installed, temperature‐controlled fans (shown in
Figure 5) to circulate cooler exterior air up through the heat ex
changer 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 inside of the
cabinet door, and are powered from either a field‐provided
‐48VDC power source or a +24VDC power source. To access
or view the fans, loosen the Phillips‐head screw at the interior
bottom of the main door (see Figure 3), then lift the cover off
the two alignment posts (Figure 5) near the top of the cover.
‐ DOOR SENSOR NOTE ‐
The door sensor will turn off the fans when the door is opened.
2.2.5 Internal‐Air Fans (“FAN B” Connector)
Two, factory‐installed, temperature‐controlled fans (shown in
Figure 2) to circulate warm interior air down through the heat ex
changer 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 inside of the
cabinet door, and are powered from either a field‐provided
‐48VDC power source or a +24VDC power source.
2.2.6 Controller Card
Boxer includes a factory‐wired controller card (Figure 9) lo
cated on the inside of the cabinet door. The card includes
connections for the fans, door alarm, temperature alarm, a 5A
fan fuse, and a fan test button. Internal wiring for the fans and
door alarm has been factory‐wired. External wiring to the pow
er source and alarm monitoring equipment is done using
“Euro‐connector” snap‐in terminal blocks which can be dis
connected 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

3.5 Removing the Knock‐outs
Knock‐outs should be removed prior to mounting the cabinet.
See Figure 6 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 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, or a pole. Op
tional mounting kits are available to support a round pole
(from 8” to 20” in diameter) or a square pedestal or post (mini
mum 8” wide). Concrete pad mounting is supported when used
with the optional Boxer battery box or skirt. All mounting hard
ware (not provided) must be capable of supporting the weight
of the Boxer cabinet (approximately 70 pounds) plus the
weight of any equipment mounted in it (up to 50 pounds). 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, vegeta
tion, and unneeded equipment or obstacles.
‐ WEIGHT NOTE ‐
The Boxer cabinet weighs 68 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 (118 pounds).
‐ 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 an H‐Frame
Follow company practice or the steps below to mount the Boxer
cabinet on an H‐frame. See Figure 11 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”
(on centers, see Figure 10). Westell recommends a height
of 30” from the ground. In addition to leaving a comfort
able installer working height, 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 (see Figure 3), 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 the added internal equipment. Insert at least
three rail nuts into each rail (compress the spring on the
nuts as needed) and slide them over to the desired mount
ing location.
4. Lift cabinet. Lift the cabinet to the mounting height.
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 3.14 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 12). 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 10 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
cabinet 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
mounting hardware to the installation site. The hardware
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 horizontal distance between the holes in
the mounting flanges is shown in Figure 10. 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” (Figure 10). Westell recommends a
minimum of 3 mounting bolts in each mounting flange. In
addition to allowing 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 hori
zontal 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.

11. Store bracket. Replace the bracket and thread the wing‐
nuts back onto their posts.
12. Return fans. Return the fan(s) to Westell for repair or re
placement (see Paragraph 7.2).
13. Install replacement fan(s). Mount the replacement fan(s)
onto their mounting studs and reverse the steps above, and

wire connections. Route the twisted fan wire through the
ferrite toroid in the same manner as the other wires are
routed, two turns.
‐ 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 by pressing the fan
test button (see Figure 16 for location).
5.3 Replacing the “Inside Air” Fans
Fans cannot be field repaired. Should a problem be suspected
with an “inside air” fan, remove the fan and return it to Westell
for service, then replace it. See Table 4 for ordering informa
tion. To remove and replace an “inside air” fan, proceed with
the following instructions.
‐ CAUTION ‐
To avoid electrical shock, turn off any DC or AC power feeds
to the controller before beginning this procedure.
1. Open the cabinet. Open the cabinet door by loosening the
two cup‐washer screws with a can wrench or 216 tool.
2. Remove fuse. Remove the 5A fan fuse from the controller
card (see Figure 9 or Figure 16 for fuse location).
3. Disconnect fan power. Disconnect the FAN B connector at
the controller card.
4. Remove wires from connector. Remove the red and black
wires from the connector. Make a note of which wires (red
or black) were inserted into which holes in the connector.
5. Replace connector. Insert the empty connector back into the
controller card, remove the fan wires from the ferrite toroid,
and note the directions the wires are wrapped through the
toroid.
6. Verify fan is off. Visually check to ensure that the fan blades
are NOT rotating.
7. Remove fan mounting nuts. Remove the nuts that secure the
fans to the inside of the cabinet door.
8. Remove fans. Lift the old fans off their mounting studs.
9. Store nuts. Replace the nuts back onto their posts.
10. Return fans. Return the fan(s) to Westell for repair or re
placement (see Paragraph 7.2).
11. Install replacement fan(s). Mount the replacement fan(s)
onto their mounting studs and reverse the steps above, and
also read the note below to secure the fan(s) and make wire
connections. Route the twisted‐pair wires through the ferrite
toroid in the same direction as the other wires, then connect
to the Euro connector.

5.4 Replacing the Door Alarm & Fan Cut‐off Switch
The door sensor switches cannot be field repaired. Should a
problem be suspected with the door sensor switch, remove the
entire door alarm switch assembly and return it to Westell for
service, then replace it. To remove and replace the door alarm
switch assembly, proceed with the following instructions.
‐ WIRE AND BLOCK DISCONNECTION NOTE ‐
The Euro‐connector blocks used for making DC distribution and
alarm wire connections facilitate a simple group disconnection of
all alarm and dc distribution wire connections; there's no need to
unscrew each wire. Simply remove the entire block by pulling the
blocks away from the panel.

Section BXM‐10N‐HE5‐20A 030‐101815 Rev. A R

‐ CAUTION ‐
To avoid electrical shock, turn off any DC or AC power feeds
to the controller before beginning this procedure.
1. Open the cabinet. Open the cabinet door.
2. Remove door sensor assembly mounting screws. Remove
the nuts that attach the door alarm sensor assembly to the
threaded posts in the lower, right, inside corner of the open
cabinet (see Figure 7 for the switch location, Figure 6 to
see the nuts).
3. Partially pull out door sensor assembly to disconnect
cable. Lift and slightly pull out the door sensor assembly
to access the cable wires. Carefully disconnect each wire
one at a time, noting which terminal was used and noting
or labelling the color or polarity of each connector, for
easy re‐connection to the new assembly.
4. Remove the door sensor assembly. Fully remove the old
door sensor assembly.
5. Install the new door sensor assembly. Reverse the steps
above to install the replacement door alarm sensor assem
bly. When re‐attaching the door alarm cable's two
connectors to the new door switch sensor assembly, verify
the following:
Sverify the connectors are routed so that they reach the
back of the door sensor,
Sverify that the door alarm cable's black wire connects
to the door switch terminal lug labelled “COM,” and
that the cable's red wire connects to the terminal lug la
belled “NO”, and
Safter re‐attaching the entire door sensor assembly to
the cabinet via the two hex nuts, verify that the door
alarm is not present when installation is complete and
power is re‐applied.
