Distinct Voltages on HPE S7506E Switch Power Supplies
Hello,
I have a H3C S7506E Switch, that has two AC supplies, I want to connect one of the supplies on a 127 V source and the other one on a 220 V source.
Both supplies are 60 Hz. Both supplies are derived from different UPS.
The 127 V supply come from a 20 kVA Tri(input)-Mono(output) UPS, which only deliver 127 V on it's output.
The 220 V supply come from a 3 kVA Mono/Biphasic UPS, which only deliver 220 V on it's output.
Both UPS are energized from distinct Circuit Boards.
Our maintenance electrician accidentally already connected one of those switchs we have on that configuration, one AC 127 V (no UPS on this one) and the other 220 V (with UPS), and I only got to know about that after some months. The equipment is running smoothly.
Can any problem arise from that configuration?
PS: The supplies are rated ~100-240 V. 50/60 Hz.
