for the ‐7HEG model) outdoor cabinet that can house and pro
tect a wide range of electronic equipment. Up to 16 vertical
Figure 1. Isometric Closed View of Boxer‐16 Cabinet
RUs (28”) of 19‐inch wide internal rack space is available to
house Network equipment such as (but not limited to) multi
plexers, copper bonding solutions, Ethernet switches and
media converters, xDSL boxes, and DS3 hand‐offs. Protective
ly mounted on the Boxer front door, separate from the interior
rack space, is a heat exchanger with built‐in fan units.
Boxer‐16 supports rapid equipment installation and wiring
through the use of adjustable and removable 19” rack channels.
An access panel is located at the rear of Boxer‐16 to allow easy
access to the rear of the installed equipment. To ensure easy ac
cess for input and out cabling, Boxer‐16 includes ample room
below the rack space as well as various sized conduit knock‐outs.
1.4 Product Mounting
The Boxer‐16 cabinet is typically mounted outdoors, above
ground on an H‐frame, a wall, square pedestal or post (minimum
8” wide), or a round pole (from 8” to 20” in diameter). Floor or
concrete pad mounting is supported when used with an optional
Boxer battery box or skirt. All mounting hardware must be capa
ble of supporting the weight of the Boxer‐16 cabinet plus the
weight of any equipment mounted in it. The Boxer‐16 cabinet is
typically located at the customer premises but can be located
anywhere a compact, weather‐tight, outdoor cabinet is required.

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,

Table 1. Knock‐out Sizes and Quantities
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.
2.2 Interior Features
The interior cabinet features are described hereunder.
2.2.1 Internal 19” Rack Channels
