Electrical Safety Precautions

!
Basic electrical safety precautions should be followed to protect
yourself from harm and the SuperServer 6021H from damage:
Be aware of the locations of the power on/off switch on the chassis
as well as the room's emergency power-off switch, disconnection
switch or electrical outlet. If an electrical accident occurs, you can
then quickly remove power from the system.
Do not work alone when working with high voltage components.
Power should always be disconnected from the system when removing
or installing main system components, such as the motherboard,
memory modules and IDE and floppy drives. When disconnecting
power, you should first power down the system with the operating
system first and then unplug the power cords of all the power supply
units in the system.
When working around exposed electrical circuits, another person who
is familiar with the power-off controls should be nearby to switch off
the power if necessary.
Use only one hand when working with powered-on electrical
equipment. This is to avoid making a complete circuit, which will
cause electrical shock. Use extreme caution when using metal tools,
which can easily damage any electrical components or circuit boards
they come into contact with.
Do not use mats designed to decrease static electrical discharge as
protection from electrical shock. Instead, use rubber mats that have
been specifically designed as electrical insulators.
The power supply power cords must include a grounding plug and must
be plugged into grounded electrical outlets.
