If an overload triggers the power supply overload protection, the system is immediately powered
off. To reset the power supply unit:
1.
Disconnect the power cord

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.
