Installation and Operation

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)

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).
