CrossPoint 300 Matrix Switchers • Installation 2-2
Installation
Mounting the Switcher
The matrix switchers are housed in rack-mountable, metal enclosures with 19" rack
ears. The amount of vertical rack space required for each switcher is as follows:
• The CrossPoint 300 84, 88, 124, and 128 are in a 3U-high enclosure.
• The CrossPoint 300 816, 168, 1212, and 1616 are in a 6U-high enclosure.
UL requirements
The following Underwriters Laboratories (UL) requirements pertain to the
installation of the matrix switcher into 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. 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.
Mounting instructions
If desired, rack mount the switcher as follows:
1 . Insert the switcher into the rack, aligning the holes in the mounting bracket
with those in the rack.
2 . Secure the switcher to the rack using the supplied bolts.
