Mounting the Switcher

The matrix switcher is housed in a rack-mountable, metal enclosure with mounting flanges for standard 19-inch racks. The sizes are as follows:

•FOX Matrix 3200 — 4U high

•FOX Matrix 7200 — 8U high

UL Guidelines

The following Underwriters Laboratories (UL) guidelines pertain to the installation of the matrix switcher into a rack.

•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. Therefore, consider installing the equipment in an environment compatible with the maximum ambient temperature specified by Extron (Tma = +32 to +122 °F [0 to +50 °C]).

•Reduced air flow — Installation of the equipment in a rack should be such 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 uneven mechanical loading does not create a hazardous condition.

•Circuit overloading — Consider the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Use appropriate consideration of equipment nameplate ratings when addressing this concern.

•Reliable earthing (grounding) — Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (such as the use of power strips).
