[j-nsp] MX960 PEMs and 3 phase power

[Tom Storey]

Hi all.

I had this idea in my head that MX960 power supplies should not be split
across phases, but I cant find anything in any documentation that says that.

Can anyone comment on whether multiple phases per PEM are supported, or
whether its even a reasonable idea to put into practice?

My thought is one PEM on one phase, such that if that phase drops, you drop
that PEM entirely. Or is it worthwhile spreading across phases to keep even
half of a PEM alive and supplying the chassis?

Thanks
