System Safety

4-1 Electrical Safety Precautions

Basic electrical safety precautions should be followed to protect yourself from harm

and the SuperServer 5017C-MTF/5017C-MTRF 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 in-•

stalling main system components, such as the serverboard, memory modules

and ﬂ oppy drive. When disconnecting power, you should ﬁ rst power down the

system with the operating system ﬁ rst 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 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 static electrical discharge as protection •

from electrical shock. Instead, use rubber mats that have been speciﬁ cally

designed as electrical insulators.

The power supply power cords must include a grounding plug and must be •

plugged into grounded electrical outlets.
