Hi all
I have been getting this recommendation from DCO 7.5.0 when a device with 6 power inlets is connected to phases L1, L2 & L3 on both AP8886 rPDU's or AP7557 rPDU's in the rack. I have noticed that the devices, typically HP C7000 blade chassis, are connected this way in the belief of balancing the load over each phase.
Q1. Is this a correct approach to balance phase load at the device level ?
Q2. If not then what is the reason for the recommendation ?
Q3. Would best practice be to connect the same phase on both rPDU's for the 6 power inlets ? (i.e. 6 x L1)
Thanks in advance

Hi Jim
Normally the recommendation we give is to connect load on just one phase. I understand that there can be circumstances where you have to do something else.
There are a couple of reasons for this the advice to put load on a single phase:
If you can balance the load by putting one chassis on L1 and one on L2 and a third on L3 and so, I would recommend that instead.
I hope that helps.
Best,
Niels
