Electrical Specifications

This section provides electrical specifications for the HP Integrity rx8620 Server.

Grounding

The site building shall provide a safety ground and protective earth for each AC service entrance to all

cabinets.

Install a protective earthing (PE) conductor that is identical in size, insulation material, and thickness to the

branch-circuit supply conductors. The PE conductor must be green with yellow stripes. The earthing

conductor described is to be connected from the unit to the building installation earth or if supplied by a

separately derived system, at the supply transformer or motor-generator set grounding point.

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 HP Integrity rx8620 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 HP Integrity rx8620 Server can receive AC input

from two different AC power sources.
