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.
Environmental Specifications
This section provides the temperature and humidity requirements, noise emission, and air flow specifications
for the server.
Operating temperature and humidity ranges might 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.
Table 2-6 lists the environmental specifications for a system processing unit with a hard disk drive.
