to the module connectors. When you install the two metal feet, the two existing screws on the
back side and I/O end of the chassis must be removed, as shown in Figure 1-11. After removing
the screws, replace them with the screws included in the NI 9901 desktop mounting kit. The

ambient temperature is between 45 °C and 55 °C, you must mount the chassis to a
metal panel or surface using the screw holes or the panel mount kit. Measure the
ambient temperature at each side of the CompactDAQ system 63.5 mm (2.5 in.) from
the side and 25.4 mm (1 in.) from the rear cover of the system. For further
