PA-5250 Power Supply Question

B_Turner — Wed, 12 Aug 2020 15:04:44 GMT

Do the power supplies within the PA-5250 load share? This is probably a real simple question but I have not found an answer within the documentation yet?

Thanks!

Hi,

my first intention was PSU2 is hot standby but I was not sure. But it seems like it is this way.

It seems like power is only drained from PSU1.
