to NSA 3130.
Before You Begin
• 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 set of jewelers Screwdrivers
• 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-nosed pliers to disconnect connections as these
can damage the soft metal or plastic parts of the
connectors.
• Before working on internal components, make sure that
the power is off. Ground yourself before touching any
internal components, by touching a metal object. Static
electricity can damage many of the electronic
components. Humid environment tend to have less static
electricity than dry environments. A grounding strap is
warranted whenever danger of static electricity exists.
Precautions
Computer components and electronic circuit boards can be
damaged by discharges of static electricity. Working on the
computers that are still connected to a power supply can
be extremely dangerous.
Follow the guidelines below to avoid damage to your
computer or yourself:
• Always disconnect the unit from the power outlet
whenever you are working inside the case.
• If possible, wear a grounded wrist strap when you are
working inside the computer case. Alternatively,
discharge any static electricity by touching the bare
metal chassis of the unit case, or the bare metal body of
any other grounded appliance.
• Hold electronic circuit boards by the edges only. Do not
touch the components on the board unless it is
necessary to do so. Don’t flex or stress the circuit board.
• Leave all components inside the static-proof packaging
that they shipped with until they are ready for
installation.
• Use correct screws and do not over tighten screws.
