the server prior to performing this procedure.
Voltages are present at various locations in the server whenever an AC power source is connected.
These voltages are present even when the main power switch is in the off position.
Failure to observe this warning can result in personal injury or damage to equipment.

ESD safety precautions can result in damage to the server.
