BA430/BA440 FRU Removal and
Replacement
This chapter describes how to remove and replace the field replaceable units
(FRUs) in the BA430/BA440 enclosure.
The following sections describe the removal procedure for each FRU. Unless
otherwise specified, you can install an FRU by reversing the steps in the
removal procedure.
System-specific FRU procedures vary slightly. As a result, some
illustrations of system-specific procedures show an example of an FRU
removal. The variations are noted in the text and in the title of the
illustration.
CAUTION:
• Only qualified service personnel should remove or install FRUs.
• Before you remove or install FRUs, power off the system.
• Static electricity can damage integrated circuits. Always use a grounded
wrist strap (29–26246–00) and a grounded work surface when working
with the internal parts of a computer system.
