To prevent catastrophic failures, design your input power sources to ensure that
adequate power is provided to the server. Use dedicated circuit breakers for all
power circuits that supply power to the server.
Electrical work and installations must comply with applicable local, state, or national
electrical codes. Contact your facilities manager or a qualified electrician to
determine what type of power is supplied to your building.
Caution – To protect your server from electrical fluctuations and interruptions, use
a dedicated power distribution system, uninterruptible power supplies, power
conditioning equipment, and lightning arresters.
The three-phase AC power source must be a center-point grounded star
configuration (type TN-C per IEC 60950). The server operates phase-to-phase, so the
neutral line of the 5-wire power cord is not connected. Only the three phase wires
and the ground wire connect to the AC power distribution.
