States and Canada.

Floor Model
The Diamond-VT is heavy (about 92 pounds fully
loaded) and requires two people to lift and carry it
safely. Place the Diamond-VT on a level surface
and make sure there is adequate space in the front
and back of the unit for proper cooling and
airflow. Continue with the general instructions.
Rack Mount
The Diamond-VT fully loaded is heavy (about 86
pounds). The unit should be handled with care and
requires two people to lift, carry and/or install it
safely.
The Diamond Array can be mounted via several
different methods in a 19” rack with 3U (5.25”) of
vertical space required. Air flow should not be
restricted in any way.
Installation in a rack may create a differential
between the room ambient temperature and the
internal ambient temperature in the rack. While
the maximum internal operating temperature of
the Diamond-VT is 47°C, you should not run the
system at the maximum temperature for extended
periods. Therefore, ensure that the room ambient
temperature is kept below 30°C for best
operation.
Each side of the rack mount Diamond-VT chassis
has three pairs of mounting holes. One is located
near the front of the rack, one near the unit’s
center of gravity, and one near the rear of the rack.
The holes accommodate 10/32 screws but the
screws can protrude no farther than .375 inches
into the rack.
Spaced rail pairs in some rackmount cabinets.
You can mount the Diamond-VT using two sets of
rail pairs spaced to accommodate the overall
length of the unit (approximately 23 inches).
Mount using the rack mount brackets on the front
and rear of the unit fastened to the rail pairs using
10/32 pan head screws with lock and flat washers.
Rack mount cabinets with stationary shelf or tray
system.
The shelf or tray must be able to support
at least 125 pounds. The shelf or tray must be
installed and secured to the rack before installing
the Diamond-VT. Secure the front of the array to
the rack with 10/32 screws, locks and flat
washers.
Sliding shelf or tray type systems should never
be used under any circumstances.
Two point open rack system. The rack must be
strong enough to support the Diamond Array
properly. Mounting brackets should be moved to
the centermost mounting holes and secured using
10/32 screws.
CAUTION CAUTION
Do not mount multiple Diamond-VT units
on a two-rail rack or mount the array above
the midpoint of a two-rail rack system.
Do not mount the Diamond-VT on any kind
of rail-type system. The array is too heavy
and does not have the proper hole pattern
for rails.
Insure the Diamond-VT has adequate air flow and
continue with the general instructions.
