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.
