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.
