HP Performance Optimized Data Center (POD) 240a Quick Setup Guide
Site requirements 14
IMPORTANT:
To provide power to the HP POD 240e NA, external transformers and
switchboards might be required. This equipment must be designed and installed to adhere with
local, state, and national codes, and installed by contractors with licensing required by the local
jurisdiction; city, township, and state.
jurisdiction; city, township, and state.
Site electrical system
To be sure that there is a complete and safe integration of the HP POD solution within your facility, HP
requires that you complete the following actions for the installed electrical system before the installation of the
HP POD solution:
•
Short circuit analysis
•
Arc flash study
•
Circuit breaker coordination study
These actions must be performed for all associated parts of the electrical power train. The majority of the
details and factors required to complete these studies are associated with the existing installed facility
infrastructure.
CAUTION:
Failure to complete these studies can cause serious issues with the electrical
integration of the POD into your electrical system.
Electrical power system configuration
A preliminary meeting with the HP POD Electrical Engineering team is necessary to discuss your decision
concerning capacity limitations and the impacts of this decision on the electrical design.
When determining the final location of the power connections, consider the following:
When determining the final location of the power connections, consider the following:
•
Distance between the facility utilities and the location of the HP POD 240e NA
•
Distance between possible UPS or generator locations and the HP POD 240e NA
•
Requirements for routing electrical feeders (underground or overhead)
The facility power connection must be installed in compliance with local electrical codes and regulations. The
HP reference electrical installation design is based on a maximum distance of 15.2 m (50 ft) or a line of sight

A 1N electrical configuration can be achieved by providing all of the required electrical feeders from a
common power source, common switchboards, and transformers.
A 2N electrical configuration can be achieved by feeding parallel power paths from independent power
A 2N electrical configuration can be achieved by feeding parallel power paths from independent power
sources, switchboards, and transformers.
IMPORTANT:
All 3-phase wye feeders for the HP POD 240e NA require that the neutrals and the
equipment grounding conductors remain isolated. Bonding of the two conductors is allowed at
the power source only.
