Mounting the Switcher
The MPX is housed in a rack-mountable, 2U high, metal enclosures with 19-inch rack ears.
UL Requirements
The following Underwriters Laboratories (UL) requirements pertain to the installation of the
MPX matrix switcher into a wall or furniture (see figure 76).
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. Therefore, consider installing the equipment in an
environment compatible with the maximum ambient temperature (Tma) specified by the
manufacturer.
2. Reduced air flow — Installation of the equipment in a rack should be such that the
amount of air ow 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 (e.g. use of power strips.
Mounting Instructions
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.
2. Secure the switcher to the rack using the supplied bolts.
