Basic electrical safety precautions should be followed to protect yourself from harm
and the SuperWorkstation 7044A-32 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 serverboard, memory modules
and the CD-ROM and fl oppy drives (not necessary for SAS/SATA drives). When
disconnecting power, you should fi rst power down the system with the operating
system 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 electrostatic discharge as protection from
electrical shock. Instead, use rubber mats that have been specifi cally designed as
electrical insulators.
The power supply power cord must include a grounding plug and must be
plugged into grounded electrical outlets.
