Install the Mediatrix unit:
on a standard 48.26 cm (19 in.) equipment rack
on a flat surface (desk, table, etc.)
Install the Mediatrix unit in a well-ventilated location where it will not be exposed to high temperatures or humidity.
Storage temperature: -20ºC to +70ºC
Operating temperature: 0ºC to +40ºC
Humidity lower than 85% and non-condensing
Do not install the Mediatrix unit in a location exposed to direct sunlight or near stoves or radiators. Excessive heat could damage the internal
components.
Unit should be positioned to be accessible for future upgrade, maintenance and troubleshooting and where cables can be easily connected.
Maintain a minimum of 25 mm (1 in.) clearance in front, in the back, on top
, and on the sides of the unit.
, under (for rack mounted units)
Keep airflow around and through the vents of the unit clear of any obstruction.
Do not put books or paper on the unit.

Wiring Guidelines
These guidelines apply for any cable, supplied or not, used with a Mediatrix unit.
Always use straight through cables.
Cables must not pull or create a lateral stress on the connectors, i.e. they must be long enough.
Cables must be installed in such a way not to present a trip hazard to personnel working in the vicinity of the equipment.
Keep cables away from:
Sources of electrical noise such as radios, transmitters, and broadband amplifiers
Power lines
Fluorescent lighting fixtures
Liquids or moisture
Heat sources

Special Considerations for BRI Cables
For optimal performance, the length of BRI cabling must take into consideration the mutual capacitance of the cable.
IMPORTANT: Information on signal reach is provided as a reference only. This information, although considered pertinent and valid, has not been tested
by Media5 corporation.
The following must also be taken into account:
Star cabling is not allowed (except for the short telephone cords).
In short bus installations, all terminals (resp. all wall-plugs) are put in parallel at arbitrary positions of the bus.
In extended bus installations, all terminals/wall-plugs are hooked in parallel on the bus on the last 30 to 50 meters of the bus.
