Mounting the Switcher

If you are going to connect VSW I AAP remote controls
to one or more inputs, identify the version of the
SW VGArs / Ars circuit board (to ensure that the
VSW I AAPs will work with this version) and configure
the switchers’ jumpers
before mounting the
switcher

. See “Identifying the Board Version and

Setting the SW VGA/Ars Jumpers” on page 2-10.

Rack mounting

UL guidelines

The following Underwriters Laboratories (UL) guidelines

pertain to the installation of the switcher into a rack (figure 2-1).

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 122 °F

(50 °C) ambient temperature (Tma) specified by Extron.

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).

Installation Overview

To install and set up the SW VGArs / Ars Series switchers,

follow these steps:

1

Turn all of the equipment off. Ensure that the video and

audio sources (computers, stereos, tape decks or other

devices), the SW VGArs / Ars switcher, the output devices

(projectors, speakers), and contact closure control device

are all turned off and disconnected from the power source.

2

If you are going to connect VSW I AAP remote controls to

one or more inputs, identify the version of the

SW VGArs / Ars circuit board (to ensure that the

VSW I AAPs will work with this version) and configure

the switcher’s jumpers. See “Identifying the Board

Version and Setting the SW VGA/Ars Jumpers” on

page 2-10.

3

Mount the switcher. See “Mounting the Switcher” on the

next page.

4

Attach the cables. See “Rear Panel Features and

Connections” later in this chapter.

5

Connect power cords and turn on the devices in the

following order:
• Output devices (projectors, monitors, speakers)

• SW VGArs / Ars Series switcher

• Contact closure/RS-232 controller

• Input devices (computers, audio sources)

6

Select an input using the front panel buttons, or the

contact closure or RS-232 controller.

7

The picture should now appear and sound should be

audible (SW VGA Ars models). If not:
• Ensure that all devices are plugged in and receiving

power.

• Check the cabling and make adjustments as needed.

• Select a different input that is known to work to check

for a display and sound.
