2 Facility Guidelines Chapter 2 9
Facility Guidelines Electrical Considerations Electrical Considerations Proper design and installation of a power distribution system for an hp rp7405/rp7410 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.
Facility Guidelines Electrical Load Requirements (Circuit Breaker Sizing) Electrical Load Requirements (Circuit Breaker Sizing) It is always a good idea to derate power distribution systems for one or more of the following reasons: • To avoid nuisance tripping from load shifts or power transients, circuit protection devices should never be run above 80% of their root-mean-square (RMS) current ratings. • Safety agencies derate most power connectors to 80% of their RMS current ratings.
Facility Guidelines Power Quality Power Quality This equipment is designed to operate over a wide range of voltages and frequencies. It has been tested and shown to comply with EMC Specification EN50082. However, damage can occur if these ranges are exceeded. Severe electrical disturbances can exceed the design specifications of the equipment. Sources of Electrical Disturbances Electrical disturbances, sometimes called glitches, affect the quality of electrical power.
Facility Guidelines Distribution Hardware Distribution Hardware This section describes wire selection and the types of raceways (electrical conduits) used in the distribution system. Wire Selection Use copper conductors instead of aluminum, as aluminum’s coefficient of expansion differs significantly from that of other metals used in power hardware. Because of this difference, aluminum conductors can cause connector hardware to work loose, overheat, and fail.
Facility Guidelines Grounding Systems Grounding Systems hp rp7405/rp7410 servers require two methods of grounding: • Power distribution safety grounding • High frequency intercabinet grounding Power Distribution Safety Grounding 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.
Facility Guidelines Grounding Systems NOTE In some cases power distribution system green (green/yellow) wire ground conductors are too long and inductive to provide adequate high frequency ground return paths. Therefore, the server is shipped with a ground strap for connecting the system cabinet to the site grounding grid (customer-supplied). When connecting this ground, ensure that the raised floor is properly grounded.
Facility Guidelines Grounding Systems • Good—Use the raised floor structure as a ground grid. In this case, the floor must be designed as a ground grid with bolted down stringers and corrosion resistive plating (to provide low resistance and attachment points for connection to service entrance ground and server equipment). The use of conductive floor tiles with this style of grid further enhances ground performance.
Facility Guidelines System Installation Guidelines System Installation Guidelines This section contains information about installation practices. Some common pitfalls are highlighted. Both power cable and data communications cable installations are discussed. NOTE In domestic installations, the proper receptacles should be installed prior to the arrival of Hewlett-Packard equipment. Refer to the appropriate installation guide for installation procedures.
Facility Guidelines Environmental Elements Environmental Elements The following environmental elements can affect an hp rp7405/rp7410 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 an hp rp7405/rp7410 server system: • Locate
Facility Guidelines Environmental Elements At altitudes above 5,000 feet (3048 m), the lower air density reduces the cooling capability of air conditioning systems. If your facility is located above this altitude, the recommended temperature ranges may need to be modified. For each 1000 feet (305 m) increase in altitude above 5,000 feet (up to a maximum of 10,000 feet), subtract 1.0° C from the upper limit of the temperature range.
Facility Guidelines Environmental Elements • Underfloor air distribution system—Downflow air conditioning equipment located on the raised floor of the computer room uses the cavity beneath the raised floor as plenum for the supply air. Perforated floor panels (available from the raised floor manufacturer) should be located around the perimeter of the system cabinets. Supply air emitted though the perforated floor panels is then available near the cooling air intake vents of the computer system cabinets.
Facility Guidelines Environmental Elements CAUTION Low humidity contributes to undesirably high levels of electrostatic charges. This increases the electrostatic discharge (ESD) voltage potential. ESD can cause component damage during servicing operations. Paper feed problems on high-speed printers are usually encountered in low-humidity environments. Low humidity levels are often the result of the facility heating system and occur during the cold season.
Facility Guidelines Environmental Elements Special precautions are necessary if the computer room is near a source of air pollution. Some air pollutants, especially hydrogen sulfide (H2S), are not only unpleasant but corrosive as well. Hydrogen sulfide damages wiring and delicate sound equipment. The use of activated charcoal filters reduces this form of air pollution. Electrostatic Discharge (ESD) Prevention Static charges (voltage levels) occur when objects are separated or rubbed together.
Facility 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.
Facility Guidelines Computer Room Safety Computer Room Safety Inside the computer room, fire protection and adequate lighting (for equipment servicing) are important safety considerations. Federal and local safety codes govern computer installations. Fire Protection The national Fire Protection Association’s Standard for the Protection of Electronic Computer Data Processing Equipment, NFPA 75, contains information on safety monitoring equipment for computer rooms.
Facility Guidelines Facility Characteristics Facility Characteristics This section contains information about facility characteristics that must be considered for the installation or operation of an hp rp7405/rp7410 server. Facility characteristics are: • Floor loading • Windows • Altitude effects Floor Loading The computer room floor must be able to support the total weight of the installed computer system as well as the weight of the individual cabinets as they are moved into position.
Facility Guidelines Facility Characteristics Table 2-3 Floor Loading Term Definitions (Continued) Term Definition Concentrated load The load that a floor panel can support on a 1-in2 (6.45 cm2) area at the panel’s weakest point (typically the center of the panel), without the surface of the panel deflecting more than a predetermined amount. Ultimate load The maximum load (per floor panel) that the floor system can support without failure. Failure expressed by floor panel(s) breaking or bending.

From Table 2-3 on page 25 b. With 0.08 in (0.2 cm) of span maximum deflection Windows Avoid housing computers in a room with windows. Sunlight entering a computer room may cause problems. Magnetic tape storage media is damaged if exposed to direct sunlight.
Facility Guidelines Space Requirements Space Requirements This section contains information about space requirements for an hp rp7405/rp7410 server. This data should be used as the basic guideline for space plan developments. Other factors, such as airflow, lighting, and equipment space requirements must also be considered. Delivery Space Requirements There should be enough clearance to move equipment safely from the receiving area to the computer room.
Facility Guidelines Space Requirements The service area space requirements, shown in Figure 2-3, are minimum dimensions. If other equipment is located so that it exhausts heated air near the cooling air intakes of the computer system cabinets, larger space requirements are needed to keep ambient air intake to the computer system cabinets within the specified temperature and humidity ranges.
Facility Guidelines Zinc Particle Contamination Zinc Particle 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.
