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.
