SKY-524 User Manual 16
2.1 Before you Begin
This chapter explains how to install the CPUs, CPU heatsinks, memory modules, and
hard drives. Instructions on inserting add on cards are also given.
2.1.1 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 sep-
arated. Putting all small components in separate containers prevents them from
becoming lost. Adequate lighting and proper tools can prevent you from accidentally
damaging the internal components.
2.1.2 Tools
The following procedures require only a few tools, including the following:
 A cross head (Phillips) screwdriver
 A T-30 Torx driver
 A grounding strap or an anti-static pad
Most of the electrical and mechanical connections can be disconnected with your
hands. It is recommended that you do not use pliers to remove connectors as it may
damage the soft metal or plastic parts of the connectors.
2.1.3 Precautions
Components and electronic circuit boards can be damaged by discharges of static
electricity. Working on a system that is connected to a power supply can be
extremely dangerous. Follow the guidelines below to avoid damage to SKY-524 or
injury to yourself.
 Ground yourself properly before removing the top cover of the system. Unplug
the power from the power supply and then touch a safely grounded object to
release static charge (i.e. power supply case). If available, wear a grounded
wrist strap. 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.
 Avoid touching motherboard components, IC chips, connectors, memory mod-
ules, and leads.
 The motherboard is pre-installed in the system. When removing the mother-
board, always place it on a grounded anti-static surface until you are ready to
reinstall it.
 Hold electronic circuit boards by the edges only. Do not touch the components
on the board unless it is necessary to do so. Do not flex or stress circuit boards.
 Leave all components inside the static-proof packaging that they ship with until
they are ready for installation.
 After replacing optional devices, make sure all screws, springs, or other small
parts are in place and are not left loose inside the case. Metallic parts or metal
flakes can cause electrical shorts.
