to your building.
Caution - Caution – Not all power cords have the same current ratings. Household
extension cords do not have overload protection and are not meant for use with
computer systems. Do not use household extension cords with your Sun product.

a grounded power outlet that is nearby the system and is readily accessible. Do not
connect a power cord to a power supply that has been removed from the system
chassis.
