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.
Cleaning the Fan Filters
A dirty fan filter can dramatically affect the cooling performance of an
NI PXIe-1075 chassis. Clean the filter whenever it becomes 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 screws. The filter cover and retainer are shown in Figure 1-2,
Rear
View of the NI PXIe-1075 Chassis .
Clean the fan filter by washing it in a mild soap solution and then
vacuuming or blowing air through it. Rinse the filter with water and allow
it to dry before reinstalling it in the chassis.
You can replace the fan filter with part number RF.09 R-30 from The Filter
Factory, Inc., Santa Ynez, CA 93460, if necessary. You also may buy from
any other vendor, as long as the filter material is 3/32” thick polyurethane
foam with a porosity of 30 ppi.
