Page 13: Building Distribution
Building Distribution Place building feeders and branch circuitry in rigid metallic conduits with proper connectors (to provide ground continuity). Ensure that all conduits that are exposed and subject to damage are constructed of rigid galvanized steel. Grounding Systems HP systems are tested and certified only with grounding systems in which a neutral return path and a protective earth are separate conductors without any inserted impedances. -
Page 14: Dual Power Source Grounding
Dual Power Source Grounding The use of dual power might create an electrical potential that can be hazardous to personnel and might cause performance issues for the equipment. When using dual power sources, measure voltage potentials with a high impedance digital multi-meter (DMM). Dual power sources might originate from two different transformers or two different UPS devices. -
Page 15: Equipment Grounding Implementation Details
Figure 1-1 Raised Floor Metal Strip Ground System Equipment Grounding Implementation Details Connect all HP equipment cabinets to the site ground grid as follows: Check that the braid contact connection points are free of paint or other insulating material and treated with a contact enhancement compound (similar to Burndy Penetrox). Check that the braid contact on each end of the ground strap consists of a terminal and connection hardware (a 1/4-inch (6.0-mm) bolt, nuts, and washers). -
Page 16: Acclimatization
NOTE: In domestic installations, install approved receptacles before the HP equipment arrives. See the appropriate installation guide for installation procedures. Acclimatization IMPORTANT: After removal of shipping material, HP recommends allowing the thermal mass of the product to equalize to the temperature and humidity of the installation facility. A minimum of 10°C (50°F) to one hour of temperature difference between the shipping/receiving facility and installation facility is required. -
Page 17: Airflow
HP equipment will operate in a broad environment within a Controlled Computer room. Temperature can range from 18–27 °C (64.40–80.60 °F) and humidity can range between 20%–80% relative humidity (rh). Use a Best Practice to gain the highest reliability by ensuring the temperature is 20–25 °C (68–77 °F) and humidity range of 40%–50% rh. -
Page 18: Equipment Orientation
Also be aware that the racking cabinets are integral to the proper environmental support for mounted equipment. See the following additional items: • Cabinet blanking panels must be used in non-populated U-space levels to prevent unpredictable air mixing.

Page 20: Dust And Pollution Control
Dust and Pollution Control Computer equipment can be adversely affected by dust and microscopic particles in the site environment. Specifically, disk drives, tape drives, and some other mechanical devices can have bearing failures resulting from airborne abrasive particles. Dust might also blanket electronic components such as printed circuit boards, causing premature failure due to excess heat or humidity buildup on the boards. -
Page 21: Metallic Particulate Contamination
http://www.isa.org/ for more information. If the environment does not meet G1 levels, third party experts in remediation should be engaged to help bring the site into compliance. This work will include verifying contaminant levels and sources, as well as determining the most effective remediation techniques. Those may include filtration and abatement of the environment by qualified professionals to remove the contaminants. -
Page 22: Air-Conditioning System Guidelines
• Humidification • Reheating • Air distribution • System controls When calculating cooling requirements, include the heat generated by lighting and personnel. For example, a person dissipates about 450 Btus per hour while performing a typical computer room task. At altitudes above 10,000 feet (3,048 m), the lower air density reduces the cooling capability of air-conditioning systems. -
Page 23: Air-Conditioning System Installation
Under-floor 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. Return air from an under-floor air-distribution system can be ducted return air (DRA) above the ceiling. -

resistance between connections, leading to equipment failures. High humidity can also have an adverse affect on some magnetic tapes and paper media. 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. -
Page 25: Acoustics
• Maintain recommended humidity level and airflow rates in the computer room. • Install conductive flooring (use conductive adhesive when laying tiles). • Use conductive wax (if waxed floors are necessary). • Ensure that all equipment and flooring are properly grounded and are at the same ground potential. -
