Hi
Can anyone logically explain why NetMETAL5 will be without the DC IN connector?
When someone wants to use the SFP it will not use POE
and then the DC connector is required.
Use twisted pair to power the device exposes unnecessary damage the LAN port.
Maybe You should remove sticker?! 
It may be exist version with and without jack
how much does it cost and where are the spec?
It’s better to use a ethernet cable for power than a powerplug !
Why do you think so?
I have lost memory about last time I powered up one bridge/cpe/access-point by jack…
Just the “desktop” units…
There are 2versions rb922GS
OK but this is fiber product (SFP fiber connection)
If there were no SFP, then the lack of the DC is OK.
However, in the case of the use of the fiber why do I have to use POE?
The LAN port is very susceptible to surges.
The use of fiber optic and dedicated power cable with DC jack solves all problems.
where to find this product ???
This product is not on the market now
Is common - also by high end licenced Wireless Products, to Power by Ethernet - even if traffic goes by fiber.
Why dont you want to Power by a Ethernet cable? Why struggle With another cable With dc plug? - its so much easier - and better, to just make an Ethernet cable - than tro struggle With a long cable With a Jack in the end to the top of a tower
Agreed.
Only one simple reason:
Hold a long ethernet cable to the LAN port without proper grounding, not once will cause damage to the Ethernet port by surge / lightning
And very often, at least we do not have how to properly grounded.
Properly installed Ethernet installation should be grounded on both sides.
Often it is impossible to do. By which the device is exposed to damage the Ethernet port
I know that you can cut a wire in an ethernet cable, etc.
But why do strange patents? When could that be done as it should be.
Really none of you do not damage the Ethernet ports from surges?
(I omit the fact that in case of damage ethernet port by surges mikrotik always refuses warranty - I think that is exactly the point here?
Breaks down, you have to buy new, and business is booming, but there is one problem while in the case of client devices OK but access devices should be as resistant to failures)
The cost of making the DC is none, is a fraction of a percent price of the device.
A significantly increases the comfort of the installation and reduces the failure rate.
HaQs, how do you get power up on a big tower?
I using this solution:
http://eltek.com/detail_products.epl?id=1142834
Given that in most location have a licensed radio links require a power supply-48V DC
To power RouterBoards i actualy use additional converters -48VDC / +24 V DC
For power I always use direct cable with a larger cross-section
There has never been a problem with that. But with damaged LAN ports with POE yes
i dont know in your contry - but here the default way of grounding is to ground at top - where ethernet goes to radio - in bottom - before the cabbin that have IDU’s and dont put the grounding inside. If tower is bigger that 30 meter, you also ground cable on its way down. Its no problem using ethernet to power units in tower’s if done right. There is problem using non grounded power inside telecom cabbin if station is grounded, but then its no problem in tower - but on ground. eltek units, i have never seen broken after a thunderstorm - nighter equipement behind.
Its possible to have no ground at all in anny place - then power will go in bottom but not radio/ethernet.
If you ground ethernet and dont do it right, you will force elektrisity to go to ethernet of radio in top of a tower. Then it will always be broken
I am not a customer who buys 5-10 pieces RB 
In the network we have actually about 2000 pcs RB.
And there are places where the lan ports are damaged every year, and are where it never had , it all depends on the location. More precisely, the severity of lightning on location
Direct DC power input and fiber data transmision always eliminate this problem
Soldering the DC especially, that RB is under prepared for it is not a big expense, and thus the device will be more versatile.
As for me netmetal after adding that DC JACK input is the perfect product
So much of this topic.
We use rugged switches with 4 802af ports and sfp which need 48V. So run fiber and 48V to the switch and connect the .ac boards with a short cable to the switch.
This is not a q about “how manny devices” out there. We have about 12000-13000 routerboards out there now, and have done like this since 2005. We have learned a bit. To have a DC connected router - newer produce less error/fail, than the devices in tower powered by ethernet. I have seen it all, and gronding is an issue to be learned, studied, and have as 100% job, by an engineer. Grounding is not easy.
