standby
If an overload triggers the power supply overload protection, the system is immediately powered off. To reset
the power supply unit perform the following steps:
1. Disconnect the power cord.
2. Determine what caused the overload by contacting a HP support representative.
3. Reconnect the power cord, then reboot the system.
If an overload occurs twice, there is an undetected short circuit somewhere.
When you use the front panel's power button to turn off the workstation, power consumption falls below the
low power consumption, but doesn't reach zero. To reach zero power consumption in "off " mode, either unplug
the workstation or use a power block with a switch.

Power Consumption and Cooling

Power consumption for a typical server is 600W/2050 Btu/h. The power consumptions listed in the following
table 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.
