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 Tank GT20
or injury to yourself.
z 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.
z Avoid touching motherboard components, IC chips,
connectors, memory modules, and leads.
z 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.
z 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.
z Leave all components inside the static-proof packaging that
they ship with until they are ready for installation.
z 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:
z All connectors are keyed to only attach one way.
z Always use the correct screw size as indicated in the
procedures.
