Mounting the SW2 DP Switcher
The SW2 DP switcher can be set on a table, mounted on a rack shelf, or mounted under a
desk, podium, or table.
Tabletop Use
Four self-adhesive rubber feet are included with the SW2 DP. For tabletop use, attach one
foot at each corner on the bottom of the unit, and place the switcher where desired.

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 that 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).
If feet were previously attached to the bottom of the unit, remove them.
Mount the switcher on the rack shelf, using two 4-40 x 3/16 inch screws in opposite
(diagonal) corners to secure the unit to the shelf (see figure 21).
Install blank panels or other units on the rack shelf as desired.
