I have 3x hEX S routers wired up to -48 now, though I have done so carefully and only utilize one copper connection out of the device to minimize the chance of anything screwing up due to misusing the product.
Also, this power supply will accept + or - 48v. https://mikrotik.com/product/pw48v_12v85w This should work in any of the recent dual power supply CCRs or CSRs. I would e-mail Mikrotik sales to confirm if it'll work with any particular model. I'm replacing my hEX S routers with CCR2004s so that I don't have to worry about that sort of thing anymore, and to have dual power. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP ----- Original Message ----- From: "Josh Luthman" <j...@imaginenetworksllc.com> To: "AnimalFarm Microwave Users Group" <af@af.afmug.com> Sent: Friday, August 7, 2020 10:41:05 AM Subject: Re: [AFMUG] a real af question Lol nice. I'm not sure about the -48v part, but Mike says it's doable so I'd safely expect he is right.
