risk of electrical shock.
Make sure to power off the equipment and disconnect the power plug from a
power outlet before cleaning or installing/removing internal optional devices.
Touching any internal device of the equipment with its power cord connected to
a power source may cause an electric shock even if the server is off-powered.

a dry cloth. Heat will be generated if condensation is formed on a dusty plug,
which may cause a fire.
