This unit is rated for operation at ambient temperatures
ranging from 0 to 40 degrees Celsius. If you mount this
unit along with other RPio622 unit(s) or other device(s) in
an EIA standard equipment rack, temperatures inside the
rack may rise, possibly resulting in impaired performance.
When rack mounting the unit, always observe the
following requirements to avoid heat buildup:
• When mounting the unit in a rack with devices such as
power amplifiers that generate a significant amount of
heat, leave 1U space or more between the RPio622 and
other equipment. Also, either leave the open spaces
uncovered or install appropriate ventilating panels to
minimize the possibility of heat buildup.
• To ensure sufficient airflow, leave the rear of the rack
open and position it at least 10 centimeters from walls
or other surfaces. If the rear of the rack cannot be left
open, install a commercially-available fan or similar
ventilating option to secure sufficient airflow. If you
have installed a fan kit, there may be cases in which
closing the rear of the rack will produce a greater
cooling effect. Refer to the rack and/or fan unit manual
If you want to recess the front panel surface of the unit
from the front edge of the rack, you can adjust the position
of the rack mount brackets to recess the unit by 50 mm or
100 mm, as shown in the illustration below.
When you install the brackets, use the same screws that you just
