UL Guidelines for Rack Mounting
The following Underwriters Laboratories (UL) guidelines pertain to the installation of a
FOX USB Extender unit into a rack.
1. Elevated operating ambient — If 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 = +122 °F [+50 °C]).
2. 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.
3. Mechanical loading — Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
4. Circuit overloading — Consideration should be given to 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. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
5. 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).
