UL requirements
The following Underwriters Laboratories (UL) requirements
pertain to the installation of the MMX 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 (Tma) specified by the
manufacturer.
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).
Mounting the MMX 32 VGA A
The MMX 32 VGA A can be set on a table, mounted on a rack
shelf, or mounted under a desk, podium, or tabletop.
Tabletop use
Four self-adhesive rubber feet are included with the switcher.
For tabletop use, attach one foot at each corner of the bottom of
the unit, and place the unit in the desired location.
Rack mounting
For optional rack mounting, mount the switcher on any of the
following rack shelves:
• VersaTools ® 19" 1U rack shelf kit (part #60-190-20)
(figure 2-1)
• VersaTools 19" basic 1U rack shelf (part #60-604-20)
• 6" deep 1U rack shelf kit (part #60-190-10)
• 6" deep basic 1U rack shelf (part #60-604-10)
• Standard universal 1U rack shelf kit (part #60-190-01)
(figure 2-2)
• Basic universal 1U rack shelf (part #60-604-01)
(2) 4-40 x 3/16" screws
Use 2 mounting holes on
opposite corners.
