AC input power
The server can receive AC input from two different AC power sources. The power receptacles are located
at the rear of the server.
A maximum of two power supplies can be installed in the server. Installing two power supplies in the
server provides 1+1 redundancy, meaning that if one power supply fails, there is still enough power
supplied to the server to operate. You must promptly replace the failed power supply to restore 1+1
functionality.
All high-line (220 V) configurations are capable of 1+1 redundancy. Low-line (110 V) configurations can
maintain 1+1 redundancy as long as the total power consumed does not exceed 800 W.
A minimum of one power supply is required to power the server. If only one power supply is installed in
the server, there is no 1+1 capability.
Power states
The server has the following power states:
• Standby power
• Full power
• Off
