installation of a power distribution system for an hp rp7405/rp7410 server requires specialized skills. Those responsible for this task good design, when coupled with proper installation practices, produces the most trouble-free operation. The electrical factors discussed in this section are: A - HP Rp7410 | Site Preparation Guide, Second Edition - hp rp7405/rp7410 Servers - Page 31
Facility Guidelines Electrical Load Requirements (Circuit Breaker Sizing) Electrical Load Requirements (Circuit Breaker Sizing) It is always a good idea to derate power distribution systems for one or more of the following reasons: • To avoid nuisance tripping from load shifts or power transients, - HP Rp7410 | Site Preparation Guide, Second Edition - hp rp7405/rp7410 Servers - Page 32
. However, testing cannot conclusively rule out loss of service. Therefore, adherence to the following guidelines provides the best possible performance of power distribution systems for server equipment: • Dedicated power source-Isolates server power distribution system from other circuits in the - HP Rp7410 | Site Preparation Guide, Second Edition - hp rp7405/rp7410 Servers - Page 33
Facility Guidelines Distribution Hardware Distribution Hardware This section describes wire selection and the types of raceways (electrical conduits) used in the distribution system. Wire Selection Use copper conductors instead of aluminum, as aluminum's coefficient of expansion differs - HP Rp7410 | Site Preparation Guide, Second Edition - hp rp7405/rp7410 Servers - Page 34
Facility Guidelines Grounding Systems Grounding Systems hp rp7405/rp7410 servers require two methods of grounding: • Power equipotential ground to all points. Main Building Electrical Ground The main electrical service entrance equipment should have an earth ground connection, as required by - HP Rp7410 | Site Preparation Guide, Second Edition - hp rp7405/rp7410 Servers - Page 35
inductive to provide adequate high frequency ground return paths. Therefore, the server is shipped with a ground strap for connecting the system cabinet to grid should be connected to the equipment cabinet and electrical service entrance ground at multiple connection points using a minimum #6 AWG - HP Rp7410 | Site Preparation Guide, Second Edition - hp rp7405/rp7410 Servers - Page 36
grid with bolted down stringers and corrosion resistive plating (to provide low resistance and attachment points for connection to service entrance ground and server equipment). The use of conductive floor tiles with this style of grid further enhances ground performance.

levels of electrostatic charges. This increases the electrostatic discharge (ESD) voltage potential. ESD can cause component damage during servicing operations. Paper feed problems on high-speed printers are usually encountered in low-humidity environments. Low humidity levels are often the result - HP Rp7410 | Site Preparation Guide, Second Edition - hp rp7405/rp7410 Servers - Page 42
Facility Guidelines Environmental Elements Special precautions are necessary if the computer room is near a source of air pollution. Some air pollutants, especially hydrogen sulfide (H2S), are not only unpleasant but corrosive as well. Hydrogen sulfide damages wiring and delicate sound equipment. - HP Rp7410 | Site Preparation Guide, Second Edition - hp rp7405/rp7410 Servers - Page 43
Facility Guidelines Environmental Elements Acoustics Computer equipment and air conditioning blowers cause computer rooms to be noisy.
