2-3 ESD Peculations
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.
• 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 a 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 serverboard and peripherals back into their antistatic bags when not in use.
• For grounding purposes, make sure your computer chassis provides excellent
conductivity between the power supply, the case, the mounting fasteners and the
serverboard.
2-4 Rack Precautions
Make sure to follow the below rack precautions:
• Ensure that the leveling jacks on the bottom of the rack are fully extended to the
floor with the full weight of the rack resting on them.
• In single rack installation, stabilizers should be attached to the rack. In multiple rack
installations, the racks should be coupled together.
• Always make sure the rack is stable before extending a component from the rack.
• You should extend only one component at a time - extending two or more
simultaneously may cause the rack to become unstable.
