Hello,
We have a customer with an industrial ethernet 4010 switch with dual PWR-RGD-LOW-DC-H power supplies. This site operates with -48 VDC power, so I reviewed the switch specifications, and they mention that the PSUs are rated for "DC 24-60V/10A", the only other available PSU option is rated for "AC 100-240V/2.0A 50-60Hz or DC 100-250V/2.0A" so I am unsure if this switch will work on this installation site.
I have found a forum post where they connect a -48VDC power supply to +48VDC power and apparently it works fine but this is the reverse of that case, so I am still unsure:

Can anyone please provide any information that will help me with this?
Thank you very much.
