Bought a 48v Eltek rectifier shelf a while back as I had been eyeing 48v rectifiers for a while and this one was a good deal. I went to rack it today and realized it won't work at all in my rack. The ears are too far in as it's made for a 2 post telecom rack, and I anticipated it would still work since my rack has some mounting points that are further in as well, so the ears do meet up at that location, the problem is there is no physical way to get the screwdriver in there to actually bolt it in because the rest of the rectifier is in the way. Something I totally did not factor in my thinking originally when I bought it. After manhandling it for a while and trying to get it in that's when I realized it was futile. So plan B was to bend in the rack ears and set it on top of some universal rails and just not bolt it in but then I realized that doesn't work either since the DC cables come out of the side, and the universal rail blocks the exit.
So now I'm basically back to the drawing board as far as my power upgrade plans go. I may need to just put it in the battery room which is going to be in the crawlspace. I was not planing on making an actual battery room, and just a vented battery box, but guess that will change. I might just extend the server room into that portion of the crawlspace and then close it in completely. The rectifier shelf can just sit on a table next to the batteries. In a way maybe this is better, as it keeps all the DC power stuff in one area and I will save money on cabling.
