Location

The unit is intended for indoor use only. Do not install the unit in an unprotected outdoor location.
Direct contact with rain, snow, wind or sun causes damage to the unit.
Do not put units above high heat or an EMF generator. High heat and EMF have an unwanted
effect on output signals and receive operations.

(RU) (1.75 inches) high and 19 inches deep. It requires a minimum rack depth of 22 inches for

When viewed from the rear of the unit, the rear panel lets power enter from the left and IF cables
enter from the right. Data and control cables enter from either side, depending on installed
options.
You can stack up to a maximum of ten units. Make sure there is a minimum of one RU of empty
space for every ten stacked units. The empty space lets air flow in the rack.
