Maintenance
This chapter describes basic maintenance procedures for the PXI-1050
chassis.
Maintenance Procedures
Service Interval
Clean the chassis fan filters at a maximum interval of six months.
Depending upon the amount of use and ambient dust levels in the operating
environment, the filters may require more frequent cleaning.
Clean dust from the chassis exterior and interior as needed, based on the
operating environment. Periodic cleaning increases reliability.
Preparation
The information in this section is designed for use by qualified service
personnel.
Caution
Many components within the chassis are susceptible to static discharge damage.
Service the chassis only in a static-free environment. Observe standard handling
precautions for static-sensitive devices while servicing the chassis. Always wear a
grounded wrist strap or equivalent while servicing the chassis.
Cleaning
Cleaning procedures consist of cleaning the exterior and interior of the
chassis and fan filters. Refer to your PXI module documentation for
information on cleaning the individual CompactPCI or PXI modules.
Caution
Always power off the chassis and disconnect the power cable before cleaning or
servicing the chassis.
Interior Cleaning
Use a dry, low-velocity stream of air to clean the chassis interior. Use a
soft-bristle brush for cleaning around components.
