General Safety Precautions

Mainboard Replaceable Soldered-in Fuses
Important: If your system comes with self-resetting PTC (Positive Temperature Coefficient)
fuses on the serverboard, they must be replaced by trained service technicians only. The new fuse
must be the same or equivalent as the one replaced. Contact your technical support organization
for details and support.
General Safety Precautions
Follow these rules to ensure general safety:
Keep the area around the Rackable C2112-4G3 system clean and free of clutter.
The Rackable C2112-4G3 system weighs approximately 85 lbs (38.6 kg.) 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 from
the system or on a table so that they won't accidentally be stepped on.
While working on the system, do not wear loose clothing such as neckties and unbuttoned
shirt sleeves, which can come into contact with electrical circuits or be pulled into a cooling
fan.
Remove any jewelry or metal objects from your body, which are excellent metal conductors
that can create short circuits and harm you if they come into contact with printed circuit
boards or areas where power is present.
After accessing the inside of the system, close the system back up and secure it to the rack
unit with the retention screws after ensuring that all connections have been made.
ESD Precautions
Caution: Electrostatic discharge (ESD) is generated by two objects with different electrical
charges coming into contact with each other. An electrical discharge is created to neutralize this
difference, which can damage electronic components and printed circuit boards.
