PDU power limitations

To reduce the risk of overload, do not exceed the rated load of any single PDU. In addition, do not load a single NEMA 5-15 (see Fig. 1-3) receptacle with more than 15 Amperes and any single IEC 320-1/C13 receptacle with more than 10 Amperes. In general, make sure that the power source circuits are able to safely provide the current that will be required by all components drawing power from them. This document assumes that 220V and 240V cables are used.

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.
