Installation
Mounting the Switcher
The Digital XPoint Matrix Switcher comes with two sets of mounting brackets. One
set is for mounting the switcher under a table or against a wall, and the other set is
for rack mounting.
Table or wall mounting
The table/wall mounting brackets extend approximately 1/4” (6.4 mm) above the
top surface of the switcher enclosure. This design allows for an air space between
the enclosure and the surface to which it is mounted. Table or wall mount the
switcher as follows:
1 . Attach the table/wall mounting brackets to the switcher with the eight
provided #8 machine screws (figure 2-1).
2 . Hold the switcher with the attached brackets against the underside of the
table or other furniture, or against the wall. Mark the location of the
screw holes of the bracket on the mounting surface.
3 . Drill 3/32” (2 mm) diameter pilot holes, 1/4” (6.4 mm) deep in the
mounting surface at the marked screw locations.
4 . Insert #8 wood screws into the four pilot holes. Tighten each screw into
the mounting surface until just less than 1/4” of the screw protrudes.
5 . Align the mounting screws with the slots in the brackets and place the
switcher against the surface, with the screws through the bracket slots.
6 . Slide the switcher slightly forward or back, then tighten all four screws to
secure the switcher in place.
Rack mounting
UL requirements
The following Underwriters Laboratories (UL) requirements pertain to the
installation of the matrix switcher into a rack (figure 2-1).
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. Therefore, consider
installing the equipment in an environment compatible with the maximum
ambient temperature (Tma) specified by the manufacturer.
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 (e.g.
use of power strips.
