Chapter 3: Replacing Pre-installed
Components
3.1 Introduction
This chapter describes how to replace all the pre-installed
components of your FT48-B4985, including the motherboard,
SAS/SATA backplane, LED control board, DVD-ROM, power
supply, cooling fans, and fan control board.
Take note of the precautions in this section when installing
your system.
3.1.1 Work Area
Make sure you have a stable, clean working environment.
Dust and dirt can get into components and cause
malfunctions. Use containers to keep small components
separated. Putting all small components in separate
containers keeps them from becoming lost. Adequate lighting
and proper tools can prevent you from accidentally damaging
the internal components.
3.1.2 Tools
The procedures that follow require only a few tools, including
the following:
• A cross head (Phillips) screwdriver
• A grounding strap or an anti-static pad
Most of the electrical and mechanical connections can be
disconnected using your fingers. It is recommended that you
do not use needle-nosed pliers to remove connectors as
these can damage the soft metal or plastic parts of the
connectors.
