System Safety

4-1 Electrical Safety Precautions

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

and the server 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 oppy drive. When disconnecting power, you should rst power down the

system with the operating system 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 specically

designed as electrical insulators.

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

plugged into grounded electrical outlets.

Note: power should always be disconnected before performing any service

on the system.
