Safety Guidelines
The safety guidelines categorized as follows:
•
"Electrical Safety" on page 27
•
"General Safety" on page 28
•
"Handling Your Server" on page 29
Observe the following basic electrical safety precautions 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 installing main
system components—such as the motherboard, memory modules, and 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
contact.
•
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.
