1 System Specifications System Configuration The following table lists the system specification for the hp Integrity rx2620 Server. Table 1-1 Hardware Specifications Component rx2620 Micro-processors 1 or 2 Itanium dual core processors, 1.4 GHz/12 MB, or 1.6GHz/18 MB — 533 MHz front side bus (1.6 GHz) — 400 MHz front side bus (1.4 GHz) Memory Supports up to 12 Double Data Rate (DDR) registered ECC Memory, in PC1600 DIMMs.
System Specifications Grounding Grounding The site building shall provide a safety ground/protective earth for each AC service entrance to all cabinets. Install a PE (protective earthing) conductor that is identical in size, insulation material, and thickness to the branch-circuit supply conductors. The PE conductor must be green with yellow stripes.
System Specifications Environmental Specifications If an overload triggers the power supply overload protection, the system is immediately powered off. To reset the power supply unit: Step 1. Disconnect the power cord. Step 2. Determine what caused the overload by contacting an HP support representative. Step 3. Reconnect the power cord, then reboot the system. If an overload occurs twice, there is an undetected short circuit somewhere.

2 General Site Preparation Guidelines The following information provides general principles and practices to consider before the installation or operation of an hp Integrity rx2620 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 Environmental Elements 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 Computer Room Preparation The following guidelines are recommended when preparing a computer room for an hp Integrity rx2620 Server: • Locate the computer room away from the exterior walls of the building to avoid the heat gain from windows and exterior wall surfaces. • When exterior windows are unavoidable, use windows that are double- or triple-glazed and shaded to prevent direct sunlight from entering the computer room.
General Site Preparation Guidelines Environmental Elements • The system should be capable of handling any future hp Integrity rx2620 Server expansion. • Air conditioning equipment air filters should have a minimum rating of 45% (based on “ASHRAE Standard 52-76, Dust Spot Efficiency Test”). • Introduce only enough outside air into the system to meet building code requirements (for human occupancy) and to maintain a positive air pressure in the computer room.
General Site Preparation Guidelines Environmental Elements Return air from an above ceiling ducted air distribution system may be ducted return air (DRA) above the ceiling, or ceiling plenum return air (CPRA). Adjust the supply air diffuser system grilles to direct the cooling air downward around the front of the hp Integrity rx2620 Server cabinets. The supply air is then available near the cooling air intake vents of the hp Integrity rx2620 Server cabinets.
General Site Preparation Guidelines Environmental Elements • Raised floor shedding • Ceiling tile shedding These particulates are not always visible to the naked eye. A good check to determine their possible presence is to check the underside of the tiles. The tile should be shiny, galvanized, and free from rust. The computer room should be kept clean. The following guidelines are recommended: • Smoking—Establish a no-smoking policy.

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 rx2620 Server.
General Site Preparation Guidelines Facility Characteristics Table 2-2 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 2-3 Typical Raised Floor Specifications (Continued) Itema Average floor load Rating 500 lb (227 kg) a. From Table 2-2 on page 29 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 • Channels or fixtures used for routing data cables and power cables • Access to air conditioning ducts, filters, lighting, and electrical power hardware • Power conditioning equipment • 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 Conversion Factors and Formulas — 1 ft. = 0.305 m — 1 CFM = 1.7m3/h • kVA Conversions 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.
