Avoid carpets in cool, dry areas. Leave an option, such as a board or chip, in its anti-static packaging until ready to install it.

Dissipate static electricity before handling any system components (for example, boards and chips) by touching a grounded metal object, such as the system’s unpainted metal chassis.

If possible, use anti-static devices, such as wrist straps and floor mats.

Always hold a chip or board by its edges. Avoid touching the components

Ton the chip or board.

Take care when connecting or disconnecting cables. A damaged cable can cause a short in the electrical circuit. Misaligned connector pins can cause damage to system components at power-on.

When installing a cable, route the cable so it is not pinched by other components and is out of the path of the system unit cover. Prevent damage to the connectors by aligning connector pins before you connect

Tthe cable.

When disconnecting a cable, always pull on the cable connector or strain- relief loop, not on the cable.
