Installation

The 1U high, quarter rack width MSW 4V SDI rs can be
mounted on a rack shelf, under a desk, or on a tabletop.

Rack mounting

For optional rack mounting, mount the MSW on any of the
following rack shelves:
• RSF 123 1U 3.5" Versatools® Rack Shelf Kit
(part #60-190-20) (figure 2-1)
• RSB 123 1U 3.5" Versatools Basic Rack Shelf
(part #60-604-20)
• RSU 126 1U 6" Universal Rack Shelf Kit (part #60-190-10)
• RSB 126 1U 6" Basic Rack Shelf (part #60-604-10)
• RSU 129 1U 9.5" Universal Rack Shelf Kit
(part #60-190-01) (figure 2-2)
• RSB 129 1U 9.5" Basic Rack Shelf (part #60-604-01)
UL requirements
The following Underwriters Laboratories (UL) requirements
pertain to the safe installation of the MSW on 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 MSW 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.
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).
Mounting instructions
On the standard rack shelf, the MSW mounts in one of four
locations to the rear of the rack or in one of four locations to the
front of the rack.
1. If they are installed, remove the feet from the bottom of the
MSW.
2. Mount the MSW on the rack shelf, using two 4-40 x 3/16"
screws in opposite (diagonal) corners to secure the MSW to
the shelf.
3. Install blank panel(s) or other unit(s) to the rack shelf.
N Only products in the VersaTools line can be mounted
to a VersaTools shelf. Most 1U rack-mountable Extron
products can be mounted on the standard shelf.
(2) 4-40 x 3/16" Screws
Use 2 mounting holes on
opposite corners.
