¡System Safety!
esd preCautions
Electrostatic discharge (ESD) is generated by two objects with dierent electrical charges
coming into contact with each other. An electrical discharge is created to neutralize this
dierence, which can damage electronic components and printed circuit boards. The
following measures are generally sucient to neutralize this dierence 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.
• Touch a grounded metal object before removing the board from the antistatic bag.
• Do not let components or PCBs come into contact with your clothing, which may
retain a charge even if you are wearing a wrist strap.
• Handle the board by its edges only; do not touch its components, peripheral chips,
memory modules or contacts.
• When handling chips or modules, avoid touching their pins.
• Put the motherboard and peripherals back into their antistatic bags when not in use.
• For grounding purposes, make sure your computer chassis provides good conductivity
between the power supply, the case, the mounting fasteners and the motherboard.
• 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.
operating preCautions
Care must be taken to ensure that the chassis cover is in place when the server is
operating to assure proper cooling. Out of warranty damage to the server can occur if
this practice is not strictly followed.
general safety preCautions
• Keep the area around the equipment clean and free of clutter.
• Servers are heavy. 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 electrical conductors.
They can create short circuits and cause injury if they come into contact with printed
circuit boards or areas where power is present.
