Given the lack of AC in the telco room, I was looking for easier ways than generating my own AC to power a few devices, but maybe that'll be a reasonable course of action. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP ----- Original Message ----- From: "Patrick Marc Preuß" <[email protected]> To: "Shawn L" <[email protected]> Cc: "Mike Hammett" <[email protected]>, "Cisco Network Service Providers" <[email protected]> Sent: Wednesday, August 4, 2021 1:06:29 PM Subject: Re: [c-nsp] DC PoE Switch Recommendations Hm a little unusual combination ;-) PoE usually is some sort of enterprise line Feature and dc input is more on the Telkom side of things, most data centers I know had two circuits of 3 phase ac. But anyway Did you have thought about using normal ac powersupplies and on the dc side using a dc / ac inverter? Something like: RS Pro 1000W Fixed Installation DC-AC Power Inverter Pure sine, 48V dc / 230V ac They are sold around 350 Euro here in Europe. > Am 04.08.2021 um 14:28 schrieb Shawn L <[email protected]>: > > If you're looking for new equipment, what about a 3850 series switch? > They're getting close to the end-of-sale from Cisco, but will still be > supported for quite a while. > > If you're looking at used equipment, it can be tough to find DC power > supplies.
