Mounting the Switcher
The MPS 112 and MPS 112CS are housed in 1U high, 17.4" wide metal enclosures
that are rack- or desk-mountable. The MBD 149 1U through-desk and rack
mounting kit (#70-077-03) is included with the switchers. The switchers may also be
surface-mounted under a table, desk, or podium, or on a wall, using the optional
Extron MBU 149 1U under-desk mounting kit (#70-222-01).

Figure 2-1 — Mounting the MPS switcher
Rack mounting
Rack mount the switcher as follows:
1. Attach the supplied rack mounting brackets to the switcher with the eight
provided #8 machine screws (figure 2-1).
2. Insert the switcher into the rack, aligning the holes in the mounting bracket
with those of the rack.
3. Secure the switcher to the rack using the supplied machine screws.
UL rack mounting requirements
The following Underwriters Laboratories (UL) requirements pertain to the safe
installation of the MPS 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 device 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.
