Electrical Specifications

1. “Maximum theoretical power” is used to describe input power at the AC input. It is expressed in Watts

and Volt-Amps to take into account power factor correction. The calculated sum is the maximum worst

case power consumption for every subsystem in the server. This number will not be exceeded by a

properly functioning server for any combination of hardware and software.

2. “Marked electrical power” is the input power measured 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.

3. “Typical maximum power” is the input power measured at the AC input expressed in Watts and

Volt-Amps, and the measured maximum worst case power consumption. This number represents the

largest power consumption for the server under laboratory conditions, using aggressive software

applications designed specifically to work the system at maximum loads and power consumption.

DC-Powered Systems

DC-powered systems must be powered by a -48 VDC Telco power source. Follow your site-specific procedures

for connecting the power and return lines to the server.
