Cleaning
Cleaning procedures consist of exterior and interior cleaning of the chassis
and cleaning the fan filters. Refer to your module user documentation for
information on cleaning the individual CompactPCI or PXI modules.
Caution
Always
disconnect the AC power cable before cleaning or servicing the chassis.
Interior Cleaning
Use a dry, low-velocity stream of air to clean the interior of the chassis.
Use a soft-bristle brush for cleaning around components.
Exterior Cleaning
Clean the exterior surfaces of the chassis with a dry lint-free cloth or a
soft-bristle brush. If any dirt remains, wipe with a cloth moistened in a mild
soap solution. Remove any soap residue by wiping with a cloth moistened
with clear water. Do not use abrasive compounds on any part of the chassis.
Caution
Avoid getting moisture inside the chassis during exterior cleaning, especially
through the top vents. Use just enough moisture to dampen the cloth.
Do
not
wash the front- or rear-panel connectors or switches. Cover these components while
cleaning the chassis.
Do
not
use harsh chemical cleaning agents; they may damage the chassis. Avoid chemicals
that contain benzene, toluene, xylene, acetone, or similar solvents.

Dirty fan filters can dramatically affect the cooling performance of a
PXI-1042 Series chassis. Clean the filters whenever they become visibly
dirty. You can easily remove the chassis air filters from the rear of the
chassis by removing the filter retainer. To remove the filter retainer, loosen
the retainer screw. The filter cover and retainer are shown in Figure 1-2,
