System Specifications Electrical Specifications Electrical Specifications This section provides electrical specifications for the hp Integrity cx2600 Server. Grounding The site building shall provide a safety ground/protective earth ground to all cabinets. A chassis ground point is provided on the server rear panel. (See Figure 2-2.
System Specifications Electrical Specifications A suitable disconnect device must be provided as part of the building installation. The purpose of the disconnect device is to provide an easy and accessible means for removing power from the product for servicing. A suitable branch circuit protection device must be provided as part of the building installation. The purpose of branch circuit protection is to limit current in the case of a fault.
System Specifications Environmental Specifications Environmental Specifications This section provides the temperature/humidity requirements, noise emission, and air flow specifications for the hp Integrity cx2600 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 Cooling Figure 2-3 Airflow Through hp Integrity cx2600 Server airflow2 Overall System Cooling The cabinet incorporates front to back airflow across the entire chassis. Four 80 mm, dual blade fans, mounted vertically in the front of the chassis, push air through the CPU, memory, and PCI sections. One 80 mm, dual blade fan and the internal power supply fans cool the lower section of the chassis.
System Specifications Environmental Specifications PCI/Mass Storage Section Cooling One 80 mm, dual blade fan pushes airflow through the PCI card cage. The fan is controlled by the room ambient temperature and runs at the speed necessary to maintain proper internal temperature throughout the PCI card cage. Typical Power Dissipation and Cooling The system configurations shown in Table 2-5 are typical of most systems and show the power and cooling values required for the listed components.
System Specifications Environmental Specifications Acoustic Noise Specification The acoustic noise specification for the HP Server is as follows: • 55 db LpA (sound pressure level at bystander position in a dedicated computer room environment temperature of <25°C).

3 General Site Preparation Guidelines The following information provides general principles and practices to consider before the installation or operation of an hp Integrity cx2600 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 • Liquidtight with RFI shield grounded (most commonly used under raised floors) Building Distribution All building feeders and branch circuitry should be in rigid metallic conduit with proper connectors (to provide ground continuity). Conduit that is exposed and subject to damage should be constructed of rigid galvanized steel.
General Site Preparation Guidelines Electrical Factors Dual power sources might originate from two separate DC sources. 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 Figure 3-1 Raised Floor Metal Strip Ground System 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.
General Site Preparation Guidelines Electrical Factors Wiring Connections Expansion and contraction rates vary among different metals. Therefore, the integrity of an electrical connection depends on the restraining force applied. Connections that are too tight compress or deform the hardware and cause it to weaken. This usually leads to high impedance, preventing circuit breakers from tripping when needed, or can contribute to a buildup of high frequency noise.
General Site Preparation Guidelines Environmental Elements Environmental Elements The following environmental elements can affect an hp Integrity cx2600 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 cx2600 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 cx2600 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 Space Requirements Space Requirements This section contains information about space requirements for an hp Integrity cx2600 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.
