Installation Overview
To install and set up the SW4 3G HD-SDI switcher,
1
Mount the switcher on a 6" or 9.5" deep rack shelf, if
desired.
2
Connect up to four video inputs to the switcher’s BNC
input connectors 1 through 4.
3
Connect one or two video output devices to the switcher’s
BNC output connectors (SDI, HD-SDI, or 3G-SDI).
4
(Optional) Wire the provided 3-pole captive screw plug to
your RS-232 cable, and connect the other end of the cable
to your computer. (See “Rear Panel Connections,” later in
this chapter.)
5
Power up the input and output devices.
6
Plug the provided power cord into the switcher’s IEC
power connector and into an AC outlet.
Rack Mounting
The 1U high, half rack width, SW4 3G HD-SDI switcher can be
mounted on a rack shelf or placed on a tabletop. For optional
rack mounting, use any of the following rack shelves:
• 1U, 6" deep Universal Rack Shelf Kit, part #
60-190-10
(RSU 126)
• 1U, 6" deep Basic Rack Shelf, part # 60-604-11 (RSB 126)
• 1U, 9.5" deep Universal Rack Shelf Kit, part
# 60-190-01 , (RSU 129)
• 1U, 9.5" deep Basic Rack Shelf, part # 60-604-02 (RSB 129)
UL rack mounting guidelines
The following Underwriters Laboratories (UL) requirements
pertain to the safe installation of the switcher on 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 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 the rack so
that the amount of air flow required for safe operation of
the equipment is not compromised.
