We thought that too. These boxes are installed in a data centre; however we
just took power to a new rack and these three machines are installed in
there, so it's not impossible there's a problem with the feed to that rack.
We did have some machines on the A and B PDUs in this rack, but we may also
try powering one from an adjacent rack.
Many thanks for your helpful suggestions, and we are working through this
with the equipment supplier (who is extraordinarily helpful and
knowledgeable and as keen to get to the bottom of this as we are). I'll
certainly let you know when we have a resolution.
Regards,
Brian.
