Handling static-sensitive devices 9 CAUTION: Never remove the cover on a power supply or any part (power backplane and AC box) that has the following label attached. Hazardous voltage, current, and energy levels are present inside the power supplies, power backplane, and AC box. There are no serviceable parts inside the power supplies, power backplane, or AC box. If you suspect a problem with one of these parts, contact an IBM service technician. Handling static-sensitive devices Static electricity, though harmless to you, can seriously damage server components or options. Note: When you are adding an internal option, do not open the static-protective package containing the option until you are instructed to do so. When you handle options and other server components, take these precautions to avoid damage from static electricity: Limit your movement. Movement can cause static electricity to build up around you. Always handle components carefully. Handle adapters, the processor board, and memory modules by the edges. Never touch any exposed circuitry. Prevent others from touching components. When you are installing a new option, touch the static-protective package containing the option to a metal expansion-slot screw or other unpainted metal surface on the server for at least two seconds. (This reduces static electricity from the package and from your body.) Chapter 4. Installing options 71
