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.

! 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 motherboard 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 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.
