4-3 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 com ponents and printed

circuit boards. The following measures are generally suffi cient 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.

!

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.
