Interior Features
The features located inside Boxer are described hereunder.
2.2.1
Door Sensor Switch
A door sensor switch for door alarm reporting purposes is lo
cated at the top, left, front corner of the cabinet (Figure 7).
This switch is factory‐prewired to a cable stub. Connect the
wires as needed to the field‐installed equipment. To temporari
ly 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.
2.2.2
Internal 19” Rack Channels
Two removable/adjustable rack channels (see Figure 8 or
Figure 13) inside the cabinet provide 19” relay rack mounting
for equipment that is to be mounted in the cabinet. With each
rack channel in the forward‐most position, the distance
between the inside of the closed front door and the channel's
front face is approximately 3.75” (equipment projection), and
the distance from the channel's rear face to the cabinet's interi
or mesh backboard is approximately 12.5”. Three rack channel
positions are available (see Figure 13), each 1” apart, if one or
two additional inches of equipment depth is needed at either
the front or back of the channel. Each rack channel also con
tains predrilled holes, with standard hole spacings (either 1”,
1.75”, or 2” rack hole patterns), to mount customer‐supplied
equipment in the cabinet. Network equipment up to 5 Rack
Units (5 RUs: 5 x 1.75 = 8.75”) high can be mounted vertically
on the internal rack inside the cabinet, either as a single piece
or multiple pieces of equipment.
‐ EXTRA RU NOTE ‐
An extra rack unit of equipment mounting space is available at
both the left and right sides of the cabinet; however, these RUs
have limited front access (partially obstructed).
2.2.3
Grounding and Bonding Center
Boxer's grounding and bonding center is located on the bottom
interior surface of the cabinet, close to the front door. A
ground plate is provided that contains five sets of ground posts
and one copper ground lug, for cable and chassis/earth ground.
Bond equipment/cables to the ground posts per company prac
tice, and connect a #6 AWG chassis or earth ground wire to the
ground lug. An Electro‐Static Discharge (ESD) wrist‐strap
jack is also located on the ground plate.

3.1
Inspecting the Equipment
‐ INSPECTION NOTE ‐
Visually inspect the unit for damages prior to installation. If the
equipment has been damaged in transit, immediately report the
extent of the damage to the transportation company and to West
ell (see Part 5 for telephone number).
‐ DESICCANT NOTE ‐
To prevent condensation during shipment and storage, Westell
includes a desiccant pack within the Boxer cabinet. Once the
electronic equipment is installed and turned‐up, the internal
power dissipation reduces the likelihood of condensation within
the cabinet. However, follow company practices for desiccant
maintenance procedures to prevent internal condensation.
