FEATURES
This section describes the exterior and interior features of the
Westell
r
Boxer
r
outdoor cabinet in more detail. Refer to
Figure 2 through Figure 6 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 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 tamper‐proof lock. Side‐wall lift ears (Paragraph 2.1.2.4)
are provided for temporary installation lift‐assistance. Mount
ing brackets (Paragraph 2.1.2.3) are attached at the top and
bottom of the back wall for permanent mounting. The bottom
floor of the main cabinet contains numerous, differently‐sized,
intact knock‐outs (Paragraph 2.1.2.7) 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 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” (shown in Figure 26). The cabi
net's cooling system is based in the door, with screened vents, a
heat exchanger and fans mounted on the door. At the inside bot
tom 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 (95 degrees). In the closed posi
tion, a gasket installed around the inside perimeter of the
cabinet door compresses against the cabinet's door frame; when
both hex cup‐washer screws (or pin‐in‐hex screws on the
‐NHE3G) are tightened, the door and gasket provide a weather‐
tight seal to protect all equipment installed inside the cabinet.
The door open sensor switch is described in Paragraph 2.2.1.
2.1.2.2
Lock(s) for Door and Rear Access Panel
To lock the door and rear access panel, tamper‐proof screws are
provided. The cup‐washer screws on the ‐NHE3 model are loos
