System Specifications Environmental Specifications Typical System Configurations The system configurations shown in Table 2-6, Typical Configuration Power Consumption Values, are typical of most systems and show the power and cooling values required for the listed components. These power and cooling values are considered typical and not maximum for the configurations shown.
System Specifications Environmental Specifications Environmental Temperature Sensor To ensure that the system is operating within the published limits, the ambient operation temperature is measured using a sensor placed on the system board. Data from the sensor is used to control fan speed and also to initiate system overtemp shutdown. Nonoperating Environment The system is designed to withstand ambient temperatures between -40° C to 70° C under nonoperating conditions.

3 General Site Preparation Guidelines The following information provides general principles and practices to consider before the installation or operation of an hp Integrity rx1620 Server. Electrical Factors NOTE Electrical practices and suggestions in this guide are based on North American practices. For regions and areas outside North America, local electrical codes will take precedence over North American electrical codes.
General Site Preparation Guidelines Electrical Factors Most computer room installations are equipped with the following fire protection devices: • Smoke detectors • Fire and temperature alarms • Fire extinguishing system Additional safety devices are: • Circuit breakers • An emergency power cutoff switch • Devices specific to the geographic location for example, earthquake protection Lighting Requirements for Equipment Servicing Adequate lighting and utility outlets in a computer room reduce the
General Site Preparation Guidelines Electrical Factors Sources of Voltage Fluctuations Voltage fluctuations, sometimes called glitches, affect the quality of electrical power.
General Site Preparation Guidelines Electrical Factors Raceway Systems (electrical conduits) (LAHJ) Raceways (electrical conduits) form part of the protective ground path for personnel and equipment. Raceways protect the wiring from accidental damage and also provide a heatsink for the wires.
General Site Preparation Guidelines Electrical Factors NOTE The green wire ground conductor mentioned above may be a black wire marked with green tape (LAHJ). Computer Safety Ground Ground all computer equipment with the green (green/yellow) wire included in the branch circuitry. The green (green/yellow) wire ground conductors should be connected to the appropriate power panel and should be sized per applicable codes (based on circuit over current device ratings).
General Site Preparation Guidelines Electrical Factors • Better— A grounded #6 AWG minimum copper wire grid mechanically clamped to floor pedestals and properly bonded to the building/site ground. • 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 HP computer equipment).
General Site Preparation Guidelines Electrical Factors 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.
General Site Preparation Guidelines Environmental Elements Environmental Elements The following environmental elements can affect an hp Integrity rx1620 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 Integrity rx1620 Ser
General Site Preparation Guidelines Environmental Elements • Reheating • 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.
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 Integrity rx1620 Server cabinets.
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 may also blanket electronic components like printed circuit boards, causing premature failure due to excess heat and/or humidity build up 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 Environmental Elements Electrostatic Discharge (ESD) Prevention Static charges (voltage levels) occur when objects are separated or rubbed together.
General Site Preparation Guidelines Facility Characteristics Facility Characteristics This section contains information about facility characteristics that must be considered for the installation or operation of an hp Integrity rx1620 Server.
General Site Preparation Guidelines Facility Characteristics Table 3-2 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.
General Site Preparation Guidelines Space Requirements Table 3-3 Typical Raised Floor Specifications (Continued) Itema Average floor load Rating 500 lb (227 kg) a. From Table 3-2 on page 38 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.
General Site Preparation Guidelines Conversion Factors and Formulas • Cabinets for cleaning materials • Maintenance area and spare parts Floor Plan Grid A floor plan grid is used to plan the location of equipment in the computer room.
General Site Preparation Guidelines Sample of an Installation Schedule Three phase kVA = V × A × √3 ⁄ 1000 • Single phase kVA = V × A ⁄ 1000 Formulas • kVA = Voltage x Current (amps) • Watts = VA x PF • BTU = Watts x 3.
