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 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
only. The new fuse must be the same or equivalent as the one replaced. Contact
technical support for details and support.
WARNING: There is a danger of explosion if the onboard battery is installed
upside down, which will reverse its polarities.
