Improper handling of static-sensitive parts can cause damage to the part. When you unpack an option or a customer replaceable unit (CRU), do not open the static-protective package containing the part until the instructions direct you to install it. When you handle options or CRUs, or perform any work inside the computer, take the following precautions to avoid static-electricity damage: • Limit your movement. Handle adapters, memory modules, and other circuit boards by the edges. €¢ When you install a static-sensitive option or CRU, touch the static-protective package containing the part to a metal expansion-slot cover or other unpainted metal surface on the computer for at least two seconds. €¢ When possible, remove the static-sensitive part from the static-protective packaging and install the part without setting it down.
