System Specifications Environmental Specifications If an overload triggers the power supply overload protection, the system is immediately powered off. To reset the power supply unit: Step 1. Disconnect the power cord. Step 2. Determine what caused the overload by contacting an HP support representative. Step 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 server, power consumption falls below the low power consumption, but doesn't reach zero. To reach zero power consumption in "off " mode, either unplug the server or use a power block with a switch. Power Consumption and Cooling The power consumptions listed in the following table are valid for a standard configuration as shipped (one 1.6 GHz processor, 1 GB of memory, one 600 W power supply, one internal hard disk drive, and one internal DVD-R drive). All information in this section is based on primary power consumptions with one power supply installed. Table 1-4 Additional Component Power Consumption Additional Component Processor SCSI hard disk drive (with I/O access) SCSI hard disk (idle) PCI card 130 W 23 W 16 W 10 to 25W Power Consumption 443.6 Btu/h 78.4 Btu/h 54.5 Btu/h 34.12 Btu/h to 85.30 Btu/h Environmental Specifications This section provides the temperature/humidity requirements, noise emission, and air flow specifications for the HP Server. Operating temperature and humidity ranges may vary depending on the installed mass storage devices. High humidity levels can cause improper disk operation. Low humidity levels can aggravate static electricity problems and cause excessive wear of the disk surface.
