Mounting the Switcher

NOTE: The SMX comes in 2U, 3U, 4U, or 5U sizes. Before attempting installation,

ensure the rack is able to accommodate your particular device size.

Install the Four uninstalled rubber feet only if the unit is to be mounted on top of a table (see
Tabletop Placement).

Tabletop Placement

For tabletop placement, install the (provided) self-adhesive rubber feet onto the four corners
of the bottom of the device.

UL Guidelines for Rack Mounted Devices

The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of the
SMX device in a rack.

1.

Elevated operating ambient temperature — If 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 SMX in an environment
compatible with the maximum ambient temperature (Tma = + 122 ˚F, + 50 ˚C) specified
by Extron.

2.

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.

3.

Mechanical loading — Mount the equipment in the rack so that a hazardous
condition is not achieved due to uneven mechanical loading.

4.

Circuit overloading — Connect the equipment to the supply circuit and consider the
effect that circuit overloading might have an overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used when
addressing this concern.

5.

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).
