Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself
from harm and the Quantum NDX NAS Tower 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 server
board, memory modules or option peripherals like a DVD-ROM (not
necessary for hot swappable drives). When disconnecting power,
you should first power down the system with the operating system
and then unplug the power cords from all the power supply
modules 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 electrostatic 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 grounded electrical outlets.
• Server board battery:
