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.
Cautions
Do
not
use abrasive compounds on any part of the chassis.
Avoid getting moisture inside the chassis during exterior cleaning.
Do
not
wash the front- or rear-panel connectors or switches. Cover these components while
cleaning the chassis.
Do
not
use chemical cleaning agents: they may damage the chassis. Avoid chemicals that
contain benzene, toluene, xylene, acetone, or similar solvents.
PXI Subsystem Fan Filter Cleaning
To easily remove the chassis cooling filters from the rear of the chassis,
remove the plastic housing attached to each fan.
To clean the fan filters, wash them in a mild soap solution and then vacuum
or blow air through them. Rinse the filters with water and allow them to dry
before reinstalling them onto the chassis.
SCXI Subsystem Fan Filter Cleaning
The fan on the rear of the SCXI subsystem cools the SCXI subsystem and
its modules. To keep the fan effective, the fan filters must be clean. Dust
and dirt accumulation reduces airflow, which makes the inside of the
chassis hotter, shortening the life of the chassis and modules. Complete the
following steps to clean the fan filters:
1.
Power off the chassis.
2.
Remove the power cable from the power-entry module.
3.
Place the chassis face down on a flat surface so that the fan is on top.
If the chassis is so heavily cabled that you cannot practically place it in
this position, leave the chassis as it is but be careful to support the fan
during removal and reinstallation to prevent breaking the fan wires.
To remove the fan filter, remove the four screws that secure the fan and
filter to the rear of the chassis. When removing the last screw, be
careful to hold the fan to prevent breaking the fan wires.
