System Power Specifications
Table 12 and Table 13 list the AC power requirements for the servers. These tables provide
information to help determine the amount of AC power needed for your computer room.

12A @ 220 VAC, See Note 22640– – –Marked Electrical Power
See Note 321712128User-Expected Maximum Power
Note 1: Maximum Theoretical Power: or “Maximum Configuration” (Input power at the ac input
expressed in Watts and Volt-Amps to take into account Power factor correction.)The calculated
sum of the maximum worst case power consumption for every subsystem in the server. This number
will never be exceeded by a functioning server for any combination of hardware and software
under any conditions.
Note 2: Marked Electrical Power: (Input power at the ac input expressed in Volt-Amps.)The Marked
Electrical Power is the rating given on the chassis label and represents the input power required
for facility ac power planning and wiring requirements. This number represents the expected
maximum power consumption for the server based on the power rating of the bulk power supplies.
This number can safely be used to size ac circuits and breakers for the system under all conditions.
Note 3: User-Expected Maximum Power: or User Expected Maximum Power, (Input power at the
ac input expressed in Watts and Volt-Amps.)The measured maximum worst case power consumption.
This number represents the larges power consumption that HP engineers were able to produce for
the server with any combination of hardware under laboratory conditions using aggressive software
applications designed specifically to work the system at maximum load. This number can safely
be used to compute thermal loads and power consumption for the system under all conditions.
