Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm and the SGI
UV 30 system from damage, as follows:
• 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 memory modules and disk drives. When disconnecting power,
you should first power down the operating system first and then unplug the power cords. The
unit has more than one power supply cord. Disconnect two power supply cords before
servicing to avoid electrical shock.
• 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.
