Maintenance
This chapter provides procedures for inspecting and cleaning, removing and
replacing internal chassis components, and isolating problems to module levels.
You must accomplish instrument-level repairs by exchanging faulty modules
with known-good modules or parts. This chapter does not provide component-
level procedures.
Preparation
The information in this chapter is designed for use by qualified service person-
nel. Read the Safety Summary at the front of this manual before attempting any
procedures in this chapter.
Preventing ESD
When performing any service which requires internal access to the mainframe
benchtop chassis, adhere to the following precautions to avoid damaging internal
circuit boards and their components due to electrostatic discharge (ESD).
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.
1. Minimize handling of static-sensitive circuit boards.
2. Transport and store static-sensitive circuit boards in their static protected
containers or on a metal rail. Label any package that contains static-sensitive
boards.
3. Discharge the static voltage from your body by wearing a grounded antistatic
wrist strap while handling these circuit boards.
4. Nothing capable of generating or holding a static charge should be allowed
on the work station surface.
5. Handle circuit boards by the edges when possible.
6. Do not slide the circuit boards over any surface.
7. Avoid handling circuit boards in areas that have a floor or work-surface
covering capable of generating a static charge.
