General Site Preparation Guidelines

The following information provides general principles and practices to consider before the installation or
operation of an HP 9000 rp4410 or HP 9000 rp4440 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.
An example would be the recommendation that the PE (Protective Earthing) conductor be
green with yellow stripes. This requirement is a North American directive and does not
override the local code requirements for a region or area outside North America.
Local authority has jurisdiction (LAHJ) and should make the final decision regarding
adherence to region-specific or area-specific electrical codes and guidelines.
Proper design and installation of a power distribution system for an HP 9000 rp4410 or HP 9000 rp4440
server requires specialized skills. Those responsible for this task must have a thorough knowledge and
understanding of appropriate electrical codes and the limitations of the power systems for computer and data
processing equipment.
In general, a well-designed power distribution system exceeds the requirements of most electrical codes. A
good design, when coupled with proper installation practices, produces the most trouble-free operation.
A detailed discussion of power distribution system design and installation is beyond the scope of this
document. However, electrical factors relating to power distribution system design and installation must be
considered during the site preparation process.
The electrical factors discussed in this section are:
•

Computer room safety

• Power consumption
• Electrical load requirements (circuit breaker sizing)
• Power quality
• Distribution hardware
• System installation guidelines
Computer Room Safety
Inside the computer room, fire protection and adequate lighting (for equipment servicing) are important
safety considerations. Federal and local safety codes govern computer installations.
Fire Protection
The National Fire Protection Association's Standard for the Protection of Electronic Computer Data
Processing Equipment, NFPA 75, contains information on safety monitoring equipment for computer rooms.
