Circuit Breaker
The Marked Electrical for the HP Integrity rx8620 server is 15 amps per line cord. The
recommended circuit breaker size is 20 amps for North America. For countries outside North
America, consult your local electrical authority having jurisdiction for the recommended circuit
breaker size.
The HP Integrity rx8620 server contains four C20 power receptacles located at the bottom rear
bulkhead. A minimum of two power cords must be used to maintain normal operation of the
server. A second set of two cords can be added to improve system availability by protecting, for
example, against power source failures or accidentally tripped circuit breakers. The server can
receive AC input from two different AC power sources.
