General System and Facility Guidelines
This chapter provides general computer facility guidelines for planning and preparing the site. Careful site
planning and preparation ensures trouble-free installation and reliable operation of HP Blade Servers.
Factors that may contribute to less than optimal equipment operation are also highlighted.
Refer to Appendix A-3 for more information on guidelines specific to the Blade Server.
NOTE
Electrical practices and suggestions in this guide are based on North American practices. For
countries 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 country outside North
America.
Local authority has jurisdiction (LAHJ) and should make the final decision
regarding adherence to country-specific electrical codes and guidelines.
Throughout this chapter, the symbol will be used to indicate Local Authority Has Jurisdiction.
Electrical Factors
Proper design and installation of a power distribution system for an HP Blade 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:
• Electrical Load Requirements (Circuit Breaker Sizing)
• Power Quality
• Distribution Hardware
• System Installation Guidelines
