GENERAL SAFETY PRECAUTIONS
Keep the area around the Server clean and free of clutter.
Servers weigh a lot. They can average about 50 lbs. (~22.68 kg)
When lifting the system, two people should lift slowly from opposite ends 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 items such as neckties and
unbuttoned shirt sleeves. They can come into contact with electrical circuits or get
pulled into a cooling fan.
Remove any jewelry or metal objects from your body, which are excellent metal
conductors and can create short circuits and harm you if they come into contact with
printed circuit boards or areas where power is present.
ESD
PRECAUTIONS
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. The
following measures are generally sufficient to neutralize this difference before contact is
made to protect your equipment from ESD:
Use a grounded wrist strap designed to prevent static discharge.
Keep all components and printed circuit boards (PCBs) in their antistatic bags until ready
for use.
