UL guidelines
The following Underwriters Laboratories (UL) guidelines pertain to the installation
of the MTPX into a rack.
1 . Elevated operating ambient temperature — If the equipment 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 MTPX 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 on 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).
Mounting instructions
The MTPX Twisted Pair matrix switchers are housed in a rack-mountable,
2U (matrix sizes 1616 and smaller) or 3U (matrix sizes 1632 and larger) high metal
enclosures with mounting flanges for standard 19" racks. If desired, rack mount the
switcher as follows:
1 . Insert the switcher into the rack, aligning the holes in the mounting bracket
with those in the rack (figure 2-1).
2 . Secure the switcher to the rack using the supplied bolts.
N Extron recommends that you allow 1U of rack space above and below the
switcher for ventilation.
