HP Performance Optimized Datacenter (POD) 240a Site Requirements Guide

Site requirements 16
In addition to the previous requirements, follow these guidelines:
• Do not treat the water with softeners, because softeners might produce foam which affects the operation
of the unit.
• Do not use well water, industrial water, water from cooling circuits, or water contaminated by any
chemicals or bacteria.
• Do not add disinfectants or anti-corrosive compounds to the water, which are potential irritants.
For additional dimensions, see the HP Site Preparation Drawing Package (on page 10).

The input power for the Critical IT Loads requires a source of 380-415V, 3phase Wye power. If it does not
already exist at the source, you might have to obtain custom transformers to derive this power. In addition to
the overall loading and KVA size, you must consider the Harmonic Content of the installation when
specifying the K-Factor of the transformers. Alternatively, you can use Harmonic Mitigating Transformers to
passively cancel the harmonics generated by the IT Equipment.
HP offers several power solutions that include automatic transfer switching, UPS backup, transformers and
output distribution switchboards to supply your power needs.
On-site connections might include:
• Main facility power to the primary side of the transformer
• Transformer to the switchboard
• Switchboard assembly to the HP POD 240a
