Part Replacement
—Only service this equipment with parts that are
exact replacements, both electrically and mechanically. Contact
National Instruments for replacement part information. Installation of
parts with those that are not direct replacements may cause harm to
personnel operating the chassis. Furthermore, damage or fire may
occur if replacement parts are unsuitable.
•
Modification
—Do
not
modify any part of the chassis from its original
condition. Unsuitable modifications may result in safety hazards.
Chassis Cooling Considerations
The NI PXIe-1065 chassis is designed to operate on a bench or in an
instrument rack. Regardless of the configuration you must provide the
cooling clearances as outlined in the following sections.
Providing Adequate Clearance
The primary cooling exhaust vent for the NI PXIe-1065 is on the top of the
chassis. The primary intake vent is on the rear of the chassis. The secondary
intake and exhaust vents are located along the sides of the chassis.
Adequate clearance between the chassis and surrounding equipment or
blockages must be maintained to ensure proper cooling of the chassis
power supply as well as the modules plugged into the chassis. These
clearances are outlined in Figure 2-1. The vent locations for the
NI PXIe-1065 chassis are shown in Figure 2-2. Failure to provide these
clearances may result in thermal-related failures in the chassis or modules.
