Preface
Installation Recommendations
Ensure you have a stable, clean working environment. Dust and dirt can get
into components and cause a malfunction. Use containers to keep small
components separated.
Adequate lighting and proper tools can prevent you from accidentally
damaging the internal components. Most of the procedures that follow
require only a few simple tools, including the following:
▪
A Philips screwdriver
▪
A flat-tipped screwdriver
▪
A grounding strap
▪
An anti-static pad
Using your fingers can disconnect most of the connections. It is recommended
that you do not use needle-nose pliers to disconnect connections as these
can damage the soft metal or plastic parts of the connectors.
