Installation Overview

To install and set up an Extron MMX 42/62 switcher for operation, follow these steps:

1Turn off all of the equipment. Ensure that the video sources and the output display are all turned off and disconnected from the power source.

2Mount the switcher. See "Mounting the Switcher", below.

3	Attach the cables. See "Rear Panel Cabling" in this chapter.
4	Plug in the power supply, then turn on the display devices
	and the input devices.

5Set the audio gain and attenuation. See the "Set input audio level" SIS commands in chapter 4, "Remote Control".

Mounting the Switcher

CInstallation and service must be performed by authorized personnel only.

The 1-inch high, quarter-rack width switcher can be placed on a tabletop, mounted on a rack shelf, mounted under a desk or tabletop, or mounted on a projector bracket.

Tabletop placement

Affix the four included rubber feet to the bottom of the unit and place it in any convenient location.

Rack mounting

For optional rack mounting, mount the switcher on any of the following rack shelves:

•RSF 123 3.5-inch deep rack shelf kit (part #60-190-20) (figure 2-1, on the next page)

•RSB 123 3.5-inch deep rack shelf (part #60-604-21)

•RSU 126 6-inch deep universal rack shelf kit (part #60-190-10)

•RSB 126 6-nch deep basic rack shelf (part #60-604-11)

UL guidelines

The following Underwriters Laboratories (UL) guidelines pertain to the installation of the matrix switcher 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 matrix switcher 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.
