Help: Taming a Desert

I'm on the new Krogan world Elaaden.  I have cleared out the vault of remnant and I believe I am at the final door to the room with the purifier on/off switch. I've extended all the bridges in the room, but the center door at the far end is blocked. The game tells me there is a console nearby. I end up scan tracing all the way back to the very first console in the room with the gravity lift. Obviously I'm tracing back to the wrong console.

Can someone describe exactly where the console is that the game is referring to, that I must use?

So there is no confusion, I'm in the big room with the container surrounded by a force field. The Pathfinder always makes the comment, 'we'll have to pick this up on the way back'.
