If you're willing to downsize a bit from the CCR, the 1100AHx4 has a 48VDC terminal block on the back in addition to 2 AC power supplies. It has switch chips though, each Ethernet port isn't connected directly to the CPU, so there are some 2.5 Gbps bottlenecks, plus it has less total CPU horsepower. It also seems a shame to waste the AC power supplies. Makes it easy to power them up on the bench though. The soon-to-be-available 4011 has the same CPU but AFAIK doesn't have a DC power input except maybe for POE.

I don't know what their acceptable range is, so I use a regulated DC-DC converter to give it exactly 24V. I've used Meanwell and Traco coverters. I drill a hole in the back of the CCR case and feed a heavy jacketed 16/2 through it and secure it with a zip tie on the inside of the case. There are two tiny holes near the corner that are just right to feed a little zip tie through....I'm not sure what their actual purpose is, but they are perfect to secure the DC cable. The polarity is not marked on the motherboard, so I always verify the polarity of the existing power wire and mark a + on the white plug with a sharpie. I leave the AC brick in their with the DC side cut off and taped up. My thinking is that if I had to I could reconnect the AC brick. -Adam On 10/26/2018 3:04 PM, SmarterBroadband wrote: Is anyone powering Mikrotik CCR routers from DC. It looks like if you pull the included AC PSU it feeds the Tik with 24volt DC. So can we just remove the supply and feed the tik from a 24v DC supply? Anyone doing this? Anyone know what the make / model of plug on the PSU?
