Potential Metallic Particulate Contamination
Metallic particulates can be especially harmful around electronic equipment. This type
of contamination may enter the data center environment from a variety of sources,
including, but not limited to, raised floor tiles, worn air conditioning parts, heating ducts,
rotor brushes in vacuum cleaners or printer component wear. Because metallic
particulates conduct electricity, they have an increased potential for creating short
circuits in electronic equipment. This problem is exaggerated by the increasingly dense
circuitry of electronic equipment.
Over time, very fine whiskers of pure metal can form on electroplated zinc, cadmium, or
tin surfaces. If these whiskers are disturbed, they may break off and become airborne,
possibly causing failures or operational interruptions. For over 50 years, the electronics
industry has been aware of the relatively rare, but possible, threat posed by metallic
particulate contamination. During recent years, a growing concern has developed in
computer rooms where these conductive contaminants are formed on the bottom of some
raised floor tiles.
Although this problem is relatively rare, it may be an issue within your computer room.
Since metallic contamination can cause permanent or intermittent failures on your
electronic equipment, Hewlett-Packard strongly recommends that your site be evaluated
for metallic particulate contamination before installation of electronic equipment.
Tools Required
You will need a T-15 Torx driver to remove the pedestal mounting screws.
