System Power Specifications Available power (output) is the maximum DC power that the power supply can supply to the system. Maximum input power is what the power supply requires from the AC line to deliver the maximum DC output (given worst case efficiency and maximum loading). Maximum input current is the worst case or highest current given the lowest input voltage and the maximum input power. Table 2-4 lists the system power specifications.

The power consumptions listed in Table 2-5 are valid for a standard configuration as shipped (one 1 GHz processor, 6 GB of memory, 650W power supply, three hard disk drives, one graphics card, one LVD SCSI card). All information in this section is based on primary power consumptions. Table 2-5 lists additional component power consumption information. Electrical Specifications 43

System Power Specifications
Available power (output) is the maximum DC power that the power supply can supply to the
system.
Maximum input power is what the power supply requires from the AC line to deliver the
maximum DC output (given worst case efficiency and maximum loading).
Maximum input current is the worst case or highest current given the lowest input voltage and
the maximum input power.
Table 2-4
lists the system power specifications.

standby
If an overload triggers the power supply overload protection, the system is immediately powered
off. To reset the power supply unit, follow these steps:
1.
Disconnect the power cord.
2.
Determine what caused the overload by contacting a HP support representative.
3.
Reconnect the power cord.
4.
Reboot the system.
If an overload occurs twice, there is an undetected short circuit somewhere.
When you use the front panel Power button to power off the server, power consumption falls
below the low power consumption, but does not reach zero. To reach zero power consumption
in “off” mode, either unplug the server or use a power block with a switch.
Power and Cooling
Typical power consumption for a server is 600W/2050 Btu/h. The power consumptions listed in
Table 2-5
are valid for a standard configuration as shipped (one 1 GHz processor, 6 GB of memory,
650W power supply, three hard disk drives, one graphics card, one LVD SCSI card).
All information in this section is based on primary power consumptions.
Table 2-5
lists additional component power consumption information.
