Mounting the Switcher
Four uninstalled rubber feet are included with the switcher. If you are going to
rack mount the switcher, mount it before you cable it (see "Rack mounting",
below), and do not install the rubber feet. If you are not rack mounting the
switcher, see "Tabletop placement", below.
Tabletop placement
For tabletop placement, install the self-adhesive rubber feet/pads (provided) onto
the four corners of the bottom of the switcher.

ISS 408 Integration Seamless Switcher • Installation
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 switcher 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 — Mount the equipment in the rack so that a hazardous
condition is not achieved due to uneven mechanical loading.
Circuit overloading — Connect the equipment to the supply circuit and
consider the effect that circuit overloading might have on overcurrent
protection and supply wiring. Appropriate consideration of equipment
nameplate ratings should be used 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 (e.g., use of power strips).
