System Safety
4-1 Electrical Safety Precautions
!
Basic electrical safety precautions should be followed to protect
yourself from harm and the SuperServer 6021i 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 IDE and floppy 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 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 specifically designed as electrical insulators.
!
The power supply power cords must include a grounding plug and
must be plugged into grounded electrical outlets.
