4-1 Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm and the
NovaScale R422/R422-INF server rom 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 boards, memory modules and processors
(not SATA drives). When disconnecting power, you should fi rst power down the
system with the operating system fi rst 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 speci fi cally designed as
electrical insulators.
The power supply power cord must include a grounding plug and must be plugged
into a grounded electrical outlet.
Serverboard Battery: CAUTION - There is a danger of explosion if the onboard battery
is installed upside down, which will reverse its polarities (see Figure 4-1 ). This battery
must be replaced only with the same or an equivalent type recommended by the
manufacturer. Dispose of used batteries according to the manufacturer's instructions.
4-2 General Safety Precautions
Follow these rules to ensure general safety:
Keep the area around the NovaScale R422/R422-INF server clean and free of clutter.
The NovaScale R422/R422-INF server weighs approximately 18.2 kg (~ 40 lbs)
when fully loaded. When lifting the system, two people at either end should lift slowly
with their feet spread out to distribute the weight. Always keep your back straight and
lift with your legs.
Place the chassis top cover and any system components that have been removed away
