What connector for the DC power input on the RB1100AHx4?

[BlueHawk]

Hi all – The RB1100AHx4 has a DC power input in the back, in addition to the two AC inputs. I’m not familiar with this input – what kind of connector does it require? Where is the DC typically coming from – a rack DC supply or something? (Sometimes I see this port described as “-48v DC telecom power”.)

Currently I am using RB1100AHx4 in production, and for input power using recti -48v DC power.

For the DC connector I got it at purchase, and just plug in the - and + cable then connect it to the -48v or recti power supply.
