Page 10: Electrical Factors
General Site Preparation Guidelines Electrical Factors Electrical Factors Proper design and installation of a power distribution system for an hp server requires specialized skills. Those responsible for this task must have a thorough knowledge and understanding of appropriate electrical codes and the limitations of the power systems for computer and data processing equipment. In general, a well-designed power distribution system exceeds the requirements of most electrical codes. -
Page 11: Power Consumption
General Site Preparation Guidelines Electrical Factors The minimum recommended illumination level is 70 foot-candles (756 lumens per square meter) when the light level is measured at 30 inches (76.2 cm) above the floor. Power Consumption When determining power requirements, you must consider any peripheral equipment that will be installed during initial installation or as a later update. -

General Site Preparation Guidelines Electrical Factors Power System Protection The hp server can be protected from the sources of many of these electrical disturbances by using: • A dedicated power distribution system • Power conditioning equipment • Over- and under-voltage detection and protection circuits •... -
Page 13: Grounding Systems
Power distribution systems consist of several parts. Hewlett-Packard recommends that these parts be solidly interconnected to provide an equipotential ground to all points. - Page 14 #6 AWG (16mm2) wire ground conductor. The following figure illustrates a metallic strip grounding system. Hewlett-Packard recommends the following approaches: • Excellent—Add a grounding grid to the subfloor. The grounding grid should be made of copper strips mounted to the subfloor.

Page 15: System Installation Guidelines
Electrical Factors Equipment Grounding Implementation Details Connect all Hewlett-Packard equipment cabinets to the site ground grid as follows: Step 1. Attach one end of each ground strap to the applicable cabinet ground lug. Step 2. Attach the other end to the nearest pedestal base (raised floor) or cable trough ground point (nonraised floor). -
Page 16: Environmental Elements
General Site Preparation Guidelines Environmental Elements Environmental Elements The following environmental elements can affect an hp server installation: • Computer room preparation • Cooling requirements • Humidity level • Air conditioning ducts • Dust and pollution control • Electrostatic discharge (ESD) prevention •... - Page 17 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 18: Humidity Level
General Site Preparation Guidelines Environmental Elements 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 hp server cabinets. •... -
Page 19: Metallic Particulate Contamination
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. -
Page 20: Electrostatic Discharge (Esd) Prevention
General Site Preparation Guidelines Environmental Elements Electrostatic Discharge (ESD) Prevention Static charges (voltage levels) occur when objects are separated or rubbed together. The voltage level of a static charge is determined by the following factors: • Types of materials • Relative humidity •... -
Page 21: Facility Characteristics
Raised floor loading is a function of the manufacturer’s load specification and the positioning of the equipment relative to the raised floor grid. While Hewlett-Packard cannot assume responsibility for determining the suitability of a particular raised floor system, it does provide information and illustrations for the customer or local agencies to determine installation requirements. - Page 22 This section contains an example of a computer room raised floor system that is satisfactory for the installation of an hp server. Based on specific information provided by Hewlett-Packard, Tate Access Floors has approved its Series 800 all-steel access floor with bolt-together stringers and 24 in. (61.0 cm) by 24 in. (61.0 cm) floor panels.
