Electrical Specifications

This section provides electrical specifications for the 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 must 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 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 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.

Power Cords
