System Specifications Electrical Specifications System Power Specifications Tables 2-4 and 2-5list the AC power requirements for the server. These tables provide information to help determine the amount of AC power needed for your computer room.
System Specifications Electrical Specifications Typical System Configurations The system configurations shown in Table 1-6, 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 Specifications This section provides the temperature/humidity requirements, noise emission, and air flow specifications for the HP Server. Temperature and Humidity Ambient intake air temperature is often different from ambient room temperature; you should measure the operating temperature and humidity directly in front of the cabinet cooling air intakes rather than just checking ambient room conditions.
System Specifications Environmental Specifications NOTE A power supply filler is required in the unused power supply slot to maintain proper airflow throughout the system. PCI/Mass Storage Section Cooling Four 127 mm fans located in the center of the chassis provide airflow for all of the PCI slots. The fans are controlled by the system temperature and run at the speed necessary to maintain proper internal temperature throughout the chassis.

2 General Site Preparation Guidelines The following information provides general principles and practices to consider before the installation or operation of an hp Integrity rx4640 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 Power System Protection The hp Integrity rx4640 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 • Screening to cancel out the effects of undesirable transmissions • Lightning arresters on power cables to protect equipment against electrical storms Precautions have been ta
General Site Preparation Guidelines Electrical Factors Grounding Systems IT Power System This product has not been evaluated for connection to an IT power system (an AC distribution system having no direct connection to earth according to IEC 60950).
General Site Preparation Guidelines Electrical Factors Dual power sources might originate from two different transformers or two different UPS devices. Voltage potentials from ground pin to ground pin of these sources should be measured and verified to be at or near 0.0 volts. Voltage levels that deviate or are measured above 3.0 volts should be further investigated. Increased voltages might be hazardous to personnel, and should be further investigated.
General Site Preparation 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. The following figure illustrates a metallic strip grounding system.
General Site Preparation Guidelines Electrical Factors Figure 2-1 26 Raised Floor Metal Strip Ground System Chapter 2
General Site Preparation Guidelines Electrical Factors Equipment Grounding Implementation Details Connect all HP 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. Check that the braid contact on each end of the ground strap consists of a terminal and connection hardware (a 1/4-in. [6.
General Site Preparation Guidelines Environmental Elements Environmental Elements The following environmental elements can affect an hp Integrity rx4640 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 rx4640 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 rx4640 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 rx4640 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.

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 Space Requirements Space Requirements This section contains information about space requirements for an hp Integrity rx4640 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.
