    General Site Preparation Guidelines Environmental Elements Environmental Elements The following environmental elements can affect a server installation: • Computer room preparation • Cooling requirements • Humidity level • Air-conditioning ducts • Dust and pollution control • ESD prevention • Acoustics (noise reduction) Computer Room Preparation The following guidelines are recommended when preparing a computer room for a server: •...
  • Page 30 General Site Preparation Guidelines Environmental Elements • Air distribution • System controls adequate to maintain the computer room within specified operating ranges. Lighting and personnel must also be included. For example, a person dissipates about 450 BTUs per hour while performing a typical computer room task. At altitudes above 10,000 feet (3048 m), the lower air density reduces the cooling capability of air-conditioning systems.

  • Page 31: Humidity Level

    General Site Preparation Guidelines Environmental Elements Return air from an under floor air-distribution system can be ducted return air (DRA) above the ceiling. Perforated floor panels (available from the raised floor manufacturer) should be located around the front of the system cabinets. Supply air emitted though the perforated floor panels is then available near the cooling air intake vents of the server cabinets.

  • Page 32: Metallic Particulate Contamination

    General Site Preparation Guidelines Environmental Elements Specifically, disk drives, tape drives, and some other mechanical devices can have bearing failures resulting from airborne abrasive particles. Dust might also blanket electronic components like printed circuit boards, causing premature failure due to excess heat or humidity buildup on the boards. Other failures to power supplies and other electronic components can be caused by metallically-conductive particles, including zinc whiskers.

    General Site Preparation Guidelines Delivery Survey Site Preparation Glossary Apparent power A value of power for AC circuits that is calculated as the product of RMS current times RMS voltage, without taking the power factor into account. ASHRAE Standard 52-76 Industry-standard term for air filtration efficiency set forth by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers, Inc.
  • Page 54 General Site Preparation Guidelines Delivery Survey Latent cooling capacity The capability of an air-conditioning system to remove heat from the air. Leakage current A term relating to current flowing between the AC supply wires and earth ground. The term does not necessarily denote a fault condition. In power supplies, leakage current usually refers to the 60-Hz current, which flows through the EMI filter capacitors that are connected between the AC lines and ground.
  • Page 55 General Site Preparation Guidelines Delivery Survey True power In an AC circuit, true power is the actual power consumed. It is distinguished from apparent power by eliminating the reactive power component that may be present.
