System Safety
Caution: Follow these basic electrical safety precautions to protect yourself from harm and the
SGI Altix XE320 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 node boards, memory modules and processors (not SATA drives). When
disconnecting power, you should first power down the system with the operating system first
and then unplug the power cord from the power supply unit.
•
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 cord must include a grounding plug and must be plugged into a
grounded electrical outlet.
