ATE Core Configurations RMX-10011 User Manual
Cooling Requirements
The ATE Core Configurations ship with several features to help facilitate proper cooling, but due
to instrumentation layout, third party devices, cabling, and mass interconnect, it is important to
do a thorough thermal assessment of the final system assembly.
Each system ships with either a high or low speed fan panel including six 120 mm fans capable
of driving a total of 540 CFM in the low speed fan panel configuration, or 1350 CFM in the high
speed fan panel configuration. Additional airflow can be added with a 1U rack mount fan panel
that utilizes three 4 in. fans (270 CFM) for targeted areas within the rack.
Each system configuration also includes a 4U vent below the rear door to facilitate airflow into
the rack. Air filters are provided and it is recommended they be properly maintained based on
environmental conditions. These filters are user serviceable and replacement kits are available
on
ni.com
.
Note
Do not block the top (exhaust vent) or air intake.
NI recommends maintaining 2U of open space directly above and below the Power Entry Panel
to allow for proper airflow through the panel.
NI also recommends against adding equipment to the top 1U of the rack, or modifying the
position of the PDU and Ethernet switch located at the top of the rack. NI has validated sufficient
cooling with the PDU and Ethernet switch in their pre-installed locations.
Exhaust
The exhaust air from all instruments should have an unobstructed pathway to exit the rack.
Arrange instruments to provide a continuous airflow path from all instrument outlets.
