2-1 Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm and
the SuperBlade from damage:
• Be aware of how to power on/off the enclosure power supplies and the individual
blades 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 blade module when removing or
installing such system components as the mainboard, memory modules and
processors.
• 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 cords must include a grounding plug and L line. It must be
plugged into grounded electrical outlets. Power input requires 110-240 VAC,
depending upon your power supply module.
• Mainboard Battery: This battery must be replaced only with the same or an
equivalent type recommended by the manufacturer (CR2032 Lithium 3V battery).
Dispose of used batteries according to the manufacturer's instructions.
• Mainboard replaceable soldered-in fuses: Self-resetting PTC (Positive Temperature
Coefficient) fuses on the mainboard must be replaced by trained service technicians
WARNING: There is a danger of explosion if the onboard battery is installed
upside down, which will reverse its polarities.
WARNING: Please handle used batteries carefully. Do not damage the battery in
any way; a damaged battery may release hazardous materials into the
environment. Do not discard a used battery in the garbage or a public landfill.
Please comply with the regulations set up by your local hazardous waste
management agency to dispose of your used battery properly.
