Electromagnetic Interference
The HP 3000 and HP 9000 Enterprise Servers are specifically designed to reduce their susceptibility to
radiated and conducted interference. Electromagnetic interference can cause a variety of computer
system problems. The Hewlett-Packard CE can advise you about many of the most common causes of
electromagnetic interference.
Environmental Considerations
NOTE
There are different environmental requirements for each peripheral
that can be used in your computer system. When you add
peripherals, refer to the peripheral’s associated data sheets to
determine its environmental specifications.
Flammable Materials
Fundamental safeguards for computer systems should include a site well away from any sources of
potential damage. The system should not be installed or operated in an environment where there is a
risk of fire or explosion due to the existence of highly flammable gases, volatile liquids, or
combustible dust.
Airborne Contaminants
Airborne contaminants and particles of a certain size and hardness can damage your computer system,
particularly disc drives. Corrosive gases and/or solvent vapors such as those from liquid spirit
duplicating equipment and wet-process photo copiers can also cause damage. Some of the most
common contaminants are dust, smoke, ash, eraser debris, food crumbs, and salty air.
The Hewlett-Packard CE can assist you in determining whether or not you need be concerned about
airborne contamination. If contamination is known or suspected, Hewlett-Packard will be available for
consultation.
Temperature and Humidity
Temperature and humidity specifications for the HP 3000 and HP 9000 Enterprise Servers are
contained in Appendix B of this manual. A good rule of thumb is to avoid extremes of either
temperature or humidity at your computer site.
