Mounting the SW4 12G HD-SDI Switchers
The SW4 12G HD-SDI switchers can be set on a table, mounted on a rack shelf, or
mounted under a desk, podium, or table.
ATTENTION:
Tabletop Use
Four self-adhesive rubber feet are included with the SW4 12G HD-SDI units. For tabletop
use, attach one foot at each corner on the bottom of the unit, and place the switcher where
desired.
Rack Mounting
The SW4 12G HD-SDI units can be mounted on a 9.5-inch, 6-inch, or 3.5-inch deep rack
shelf. They can also be mounted vertically to the front or back rack support. For mounting
procedures, see the instructions provided with the mounting option.

•
Installation and service must be performed by authorized personnel only.
•
L'installation et l'entretien doivent être effectués uniquement par un technicien
qualifié.
Elevated operating ambient temperature — If the equipment is installed in a closed
or multi-unit rack assembly, the operating ambient temperature of the rack environment
may be greater than room ambient temperature. Therefore, install the equipment in
an environment compatible with the maximum ambient temperature (TMA = +122 °F,
+50 °C) specified by Extron.
Reduced air flow — Install the equipment in a rack so the amount of air flow required
for safe operation of the equipment is not compromised.
Mechanical loading — When mounting the equipment in the rack, ensure that uneven
mechanical loading does not cause a hazardous condition.
Circuit overloading — When connecting the equipment to the supply circuit, consider
the effect that circuit overloading might have on overcurrent protection and supply
wiring. Consider equipment nameplate ratings when addressing this concern.
Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted
equipment. Pay particular attention to supply connections other than direct connections
to the branch circuit (for example, use of power strips).
