you from harm and the system from damage:

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 or memory modules. When

disconnecting power, you should first turn off the system

and then unplug the power cords from all the power supply

modules 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.

– The power supply power cords must include a grounding

plug and must be plugged into grounded electrical outlets.

The unit has more than one power supply cord. Disconnect

both power supply cords before servicing to avoid electrical
