3-Phase 16A PDU & c7000 BladeSystem enclosure question

[chuckk281]

Martin had a customer question regarding input power for a c7000 enclosure:

***************************************************************

My customer wants to install a 3 Phase 16A C7000 enclosure in a 47U rack with on both sides two 1 phase 16A PDU’s.

Can he cut the wires and connect 3 CEE 7/7 “Schuko” European power cords (1 Phase 16A) on each Feed of the enclosure.

Can it technically, and is this supported?

Juergen had some info for Martin:

Hello Martin

If I understand your request right the customer wants to do modifications on both 3-phase power cords directly attached to the HP BladeSystem enclosure. A 3-phase connection typically means in EMEA about 400V phase-to-phase, and 230V phase-to-neutral. In general, this modification will have an impact on the enclosure warranty. But beside of this, 3-phase 16A provides 3x the power of a single-phase 16A line (11kVA vs. 3,7kVA). As a result, connecting the modified 3-phase power cords to a single-phase PDU (3,7kVA) will overload this one.

Another reason not to do this, there is no power outlet for CEE 7/7 “Schuko” on any of our HP PDUs.

What is the reason for this action, is there no 3-phase outlet available onsite?

If yes, the electrician may provide a separate junction box with breakers to do the job without impact on enclosure warranty.

If I’ve misunderstood the request please provide some more details and I’ll try again.
