My server room has 3 wall outlet boxes named A, B and C.
I want to plug in my server's dual power supplies in an optimal manner. Each will connect to a UPS, but I want each UPS to be connect to a different side of the breaker box which will give maximum redundancy.
I decided to check if all 3 boxes went to the same side of the breaker box so I ran a voltage meter between the hot side of each box.
A to B = 0 volts
A to C = 220 volts.
I therefore wired one UPS to box A and the other to box C so, the problem is solved.
But, I have one question. Does Dell's Open Manage software have a function that would eliminate the need for a voltage meter?
In other words can Open Manage show the voltage between the line side of the two power supplies?
