System Specifications Electrical Specifications Electrical Specifications This section provides electrical specifications for rp8400 servers. Grounding The site building shall provide a safety ground/protective earth for each AC service entrance to all rp8400 cabinets. Install a PE (protective earthing) 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 rp8400 server is 15 amps. 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 rp8400 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 rp8400. 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 rp8400 is capable of receiving AC input from two different AC power sources. System Power Requirements Table 1-4 and Table 1-5 on page 8 list the AC power requirements for a rp8400 server. These tables provide information to help determine the amount of AC power needed for your computer room. To determine the overall power requirements of your specific system, see Table A-3 on page 47 and Table A-4 on page 47.

Electrical Specifications
This section provides electrical specifications for rp8400 servers.
Grounding
The site building shall provide a safety ground/protective earth for each AC service entrance to all rp8400
cabinets.
Install a PE (protective earthing) 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 rp8400 server is 15 amps. 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 rp8400 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 rp8400. 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 rp8400 is capable of receiving AC input from two different AC power sources.
System Power Requirements
Table 1-4 and Table 1-5 on page 8 list the AC power requirements for a rp8400 server. These tables provide
information to help determine the amount of AC power needed for your computer room. To determine the
overall power requirements of your specific system, see Table A-3 on page 47 and Table A-4 on page 47.
