System Specifications Environmental Requirements 12 Chapter 1
2 Electrical and Environmental Guidelines This chapter provides guidelines for planning and preparing the site. Careful site planning and preparation ensures trouble-free installation and reliable operation of rp8400 servers. Factors that may contribute to less than optimal equipment operation are also highlighted. • “Electrical Factors” on page 15 discusses computer room safety, electrical load requirements, power quality, distribution hardware, and system installation guidelines.
Electrical and Environmental Guidelines • 14 “Environmental Elements” on page 21 discusses computer room preparation, cooling and humidity requirements, dust and pollution control, electrostatic discharge prevention, and acoustics.
Electrical and Environmental Guidelines Electrical Factors Electrical Factors Proper design and installation of a power distribution system for a rp8400 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.
Electrical and Environmental 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. Electrical Load Requirements (Circuit Breaker Sizing) NOTE Local authority has jurisdiction [LAHJ] and should make the final decision regarding adherence to country- specific electrical codes and guidelines.
Electrical and Environmental Guidelines Electrical Factors • Lightning arresters on power cables to protect equipment against electrical storms Every precaution has been taken during power distribution system design to provide immunity to power outages of less than one cycle. However, testing cannot conclusively rule out loss of service.
Electrical and Environmental Guidelines Electrical Factors Grounding Systems rp8400 servers require two methods of grounding: • Power distribution safety grounding • High frequency intercabinet grounding Power Distribution Safety Grounding [LAHJ] The power distribution safety grounding system consists of connecting various points in the power distribution system to earth ground using green (green/yellow) wire ground conductors.
Electrical and Environmental Guidelines Electrical Factors Raised Floor “High Frequency Noise” Grounding If a raised floor system is used, install a complete signal grounding grid for maintaining equal potential over a broad band of frequencies. The grounding grid should be connected to the equipment cabinet and electrical service entrance ground at multiple connection points using a minimum #6 AWG (16mm2) wire ground conductor. See Figure 2-1 on page 19 illustrates a metallic strip grounding system.
Electrical and Environmental 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). Step 3.
Electrical and Environmental Guidelines Environmental Elements Environmental Elements The following environmental elements can affect a rp8400 server installation: • Computer room preparation • Cooling requirements • Humidity level • Air conditioning ducts • Dust and pollution control • Electrostatic discharge (ESD) prevention • Acoustics (noise reduction) Computer Room Preparation The following guidelines are recommended when preparing a computer room for a rp8400 server system: • Locate th
Electrical and Environmental Guidelines Environmental Elements • Humidification • Reheating • Air distribution • System controls adequate to maintain the computer room within the operating ranges listed in Table 1-7 on page 9. 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.
Electrical and Environmental Guidelines Environmental Elements If a ceiling plenum return air system or a ducted ceiling return air system is used, the return air grill(s) in the ceiling should be above the exhaust area or the exhaust row.
Electrical and Environmental Guidelines Environmental Elements Dust and Pollution Control Computer equipment can be adversely affected by dust and microscopic particles in the site environment. Specifically, disk drives, tape drives, and some other mechanical devices can have bearing failures resulting from airborne abrasive particles. Dust may also blanket electronic components like printed circuit boards causing premature failure due to excess heat and/or humidity build up on the boards.
Electrical and Environmental Guidelines Environmental Elements 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.
Electrical and Environmental Guidelines Environmental Elements Acoustics Computer equipment and air conditioning blowers cause computer rooms to be noisy. Ambient noise level in a computer room can be reduced as follows: • Dropped ceiling—Cover with a commercial grade of fire-resistant, acoustic rated, fiberglass ceiling tile. • Sound deadening—Cover the walls with curtains or other sound deadening material. • Removable partitions—Use foam rubber models for most effectiveness.
3 Facility Guidelines This chapter describes facility characteristics and provides guidelines for preparing the computer room. • “Facility Characteristics” on page 28 discusses architectural issues. • “Space Requirements” on page 31 discusses the amount of floor space required by the components.
