Installation and Operation

Installation Overview

To install and set up the VSW 2VGA A for operation, follow
these steps:
Turn all of the equipment off. Make sure that the
1
video and audio sources (computers, stereos, tape
decks, or other devices), the VSW 2VGA A,
the output devices (projectors, speakers), and the contact
closure control device are all turned off and
disconnected from the power source.
2 If you are going to daisy chain two or more switchers
with VSW I AAP control panels, identify the revison of
the VSW 2VGA A board (for configuring the VSW I AAPs)
and configure the switchers' jumpers. See "Identifying the
Board Revision and Setting the VSW 2VGA A Jumpers" on
page 2-14.
3 If desired, mount the switcher. See "Mounting the
VSW 2VGA A" in this chapter.
4 Attach the cables. See "Front Panel Features" and "Rear
Panel Features" in this chapter.
5 Connect power cords and turn on the devices in the
following order: output devices, contact closure controller,
VSW 2VGA A switcher, and input devices.
Select an input using the front panel input toggle switch or
6
the contact closure controller.
The image should now display, and sound should be
7
audible. If not, ensure that all devices are plugged in and
receiving power. Check the cabling and make adjustments
as needed. Select a different input to check for a picture
and sound.

The VSW 2VGA A can be mounted in a rack, or under or
through furniture, using one of the following optional mounting
kits:
• RSF 123 3" VersaTools® rack shelf kit (part #60-190-20)
• RSB 123 3" VersaTools rack shelf (part #60-604-20)
• RSU 126 6" deep universal rack shelf kit (part #60-190-10)
• RSB 126 6" deep basic rack shelf (part #60-604-10)
• RSU 129 9" 1U universal rack shelf kit (part #60-190-01)
• RSB 129 9" 1U basic rack shelf (part #60-604-01)
• MBU 125 Under-desk mount kit (part #70-077-01)
• MBD 129 Through-desk mount kit (part #70-077-02)
When mounting the switcher, take cabling and power
availability into consideration. Follow the appropriate
mounting procedure on the following pages.

Rack shelf mounting

UL rack mounting requirements

The following Underwriters Laboratories (UL) requirements
pertain to the safe installation of the VSW 2VGA A 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 switcher
in an environment compatible with the maximum ambient
temperature (Tma = +113° F, +45° 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.
Circuit overloading — Connect the equipment to
4.
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.
5. Reliable earthing (grounding) — Maintain reliable
grounding of rack-mounted equipment. Pay particular
attention to supply connections other than direct
connections to the branch circuit (e.g. use of power strips).
