Installation Overview

To install and set up the SW2/SW4 switcher,

1Mount the switcher on a rack shelf or furniture, if desired.

2Connect input source(s) to one or more SW2/SW4 video input connectors.

3Connect an output device to the SW2/SW4 output connector.

4Connect the audio connectors of your input device(s) to the SW2/SW4 audio input 3.5 mm TRS mini jacks.

5Wire one of the provided 5-pole captive screw plugs to your audio output cable, and connect your output device’s audio input to the SW2/SW4 captive screw audio output connector.

6Insert the other provided captive screw plug into the Remote/Auto-sw connector on the SW2/SW4 rear panel. Wire your RS-232 cable to pins 1, 2, and 3 of this plug, and connect the other end of the cable to your computer. (See "Wiring for RS-232," later in this chapter.)

7If using autoswitching, jumper-connect together pins 4 and 5 of the 5-pin captive screw plug that you plugged into the Remote/Auto-Sw connector in step 6 . (See “Enabling autoswitching,” later in this chapter.)

8If necessary, wire the provided 2-pin captive screw connector to the external power supply. (See “Wiring the Power Connector,” later in this chapter.)

9Power on the output display.

10Apply power to the switcher.

11Power on the input device(s).

Mounting the SW DVI A Series

The SW DVI A Series switcher can be set on a table, mounted on a rack shelf, or mounted under a desk, podium, or table.

Tabletop use

Four self-adhesive rubber feet are included with the SW2/SW4. For tabletop use, attach one foot at each corner on the bottom of the unit, and place the switcher in the desired location.

Rack mounting

For optional rack mounting, do not install the rubber feet. Mount the switcher on any of the following rack shelves:

•RSB 123 1U, 3.5" Deep VersaTools® Basic Rack Shelf (part #60-604-20)

•RSF 123 1U, 3.5" Deep VersaTools Rack Shelf Kit (part #60-190-20)

•RSB 126 1U, 6" Deep Basic Rack Shelf (part #60-604-10)

•RSU 126 1U, 6" Deep Universal Rack Shelf Kit (part #60-190-10)

•RSB 129 1U, 9.5" Deep Basic Rack Shelf (part #60-604-01)

•RSU 129 1U, 9.5" Deep Universal Rack Shelf Kit (part #60-190-01)

•MBB 100 VersaTools Back of the Rack Mounting Kit (part #70-367-01)

UL rack mounting guidelines

The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of the equipment in a rack.

1. Elevated operating ambient temperature — If the equipment is 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 equipment 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.

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.

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).
