4-1 Electrical Safety Precautions
!
Basic electrical safety precautions should be followed to protect yourself from
harm and the SuperWorkstation 5037A-I 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 install-
ing main system components, such as the motherboard, memory modules and
the DVD-ROM. When disconnecting power, you should first power down the sys -
tem with the operating system. The unit has more than one power supply cord.
Disconnect both power supply cords before servicing to avoid electrical shock.
•
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 neces-
sary.
•
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 electrostatic discharge as protection from
electrical shock. Instead, use rubber mats that have been specifically designed
as electrical insulators.
•
The power supply power cord must include a grounding plug and must be
plugged into grounded electrical outlets.
