Dear all, A moment of clarity occurred to me, just before I shipped out some anchor nodes: the power plugs on the back of box (C7 type) won't easily be connected in most datacenter deployments. I found these cute plugs [1], which can be ordered here [2]. Hope this helps others :-) How have others solved the issue? Any ideas on how to get these Anchors to run on 48V DC (for telco-style deployment)? Kind regards, Job [1] - http://www.kempelektroniks.nl/FilesContent/menu/menu000250/images_iecc7adapt...

4.1 J7, DC Input Jack The 2.1mm DC Power Jack should be used for connecting a small wall mount unregulated power adapter, supplying 6V - 28V DC at minimum 15 VA, preferable more depending on expansion added, with a 5.5mm outside, 2.1mm inside female power plug with plus at center pin. It is protected against reverse polarity. Please note that standard unregulated power transformers can supply much higher voltage that the specified nominal voltage, so when using such a type it's recommended to use one that is specified for 16V DC or less.
So all you need to do is transform from -48VDC to say +16V/1A and feed that to a 2.1mm connector. Nick

FYI, there's also a power supply header on the board (instead of using the 2.1mm jack): 4.15 JP15, DC Power 4 pins AMP MTA100 header, for connecting of an internal power supply of 5V to 28V DC., Pin 1 is the top pin, closest to JP 16. Please note that JP15 is NOT protected against reverse voltage. Regards, Colin

We have suggested to all anchor hosts who are ordering from the supplier we are working with to also order the converter cable, should they need it, at no extra cost: https://encrypted.kd85.com/ripe-atlas-anchor.html "C14 Power cable, for use in racks, back of UPS, ..." I asked Wim to clarify the page even more, just in case it is not clear to more people then just Job. Thanks for flagging this! Vesna
