7. Holding the module by the ejector handle, slide it into an empty slot,

ensuring that the base card (on the left when looking at the front of the

module) engages with the card guides in the chassis.

8. Slide the module completely into the chassis and latch by pulling up on

the ejector handle.

9. Tighten the captive screws at the top and bottom of the module front

panel.

10. Before operating the module, install all chassis covers and filler panels.

Missing filler panels disrupt the necessary air circulation in the chassis.

Note NI recommends that you install slot blockers between

modules to maximize air flow. NI recommends using the PXI

Chassis Slot Blocker Kit, part number 778678-01, available for

purchase at ni.com.

NI PXI modules are sensitive instruments that should be handled carefully.

Do not expose the module to temperatures or humidity beyond the rated

maximums. Keep the module free of dust by cleaning with compressed air

only. Do not clean the module with any solvents or liquids. For more

information about module cooling, refer to the guidelines in the Maintain

Forced-Air Cooling Note to Users included with your NI digital waveform

generator/analyzer.

Maintaining PXI Systems

Clean the fan filters on the chassis regularly to prevent air circulation path

blockage. Cleaning frequency depends on the amount of use and the

operating environment. For specific information about cleaning procedures,

and other recommended maintenance, refer to the module specifications and

the chassis user documentation.

Uninstalling PXI Modules

When removing PXI modules from the chassis, first power down the chassis.

Then ensure that you are grounded with a grounding strap or are touching a

grounded metal surface. Toavoid ESD, do not touch the exposed pins of the

PXI connector or any exposed circuitry on the module. When not in use, PXI

modules should be stored in the original antistatic packaging to avoid

damage.

Caution During operation the metal surfaces of PXI modules may

become hot. Be careful when removing the module from the chassis

or when moving it to a different peripheral slot. When removing the

module, hold it by the ejector handle and front panel only.
