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 the
Transport GX21 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. Alter-
natively, 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 modules, and leads.
• The motherboard is pre-installed in the system.
When removing the motherboard, 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 packag-
ing that they ship with until they are ready for installa-
tion.
• 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.
Notes:
• All connectors are keyed to only attach one way.
• Always use the correct screw size as indicated in the
procedures.
