I am setting up a lab for learning purposes. I don't have a rack yet, but I just purchased a Supermicro 2U enclosure on eBay with some rails.
How does it work with connecting the server to the rack? I've got no experience with rack mounted equipment, and I haven't bought a rack yet. I want to make sure I don't mix the wrong types of equipment.
Generally all 19" 4 post racks will work with all 4 post rails, if they're both "square hole universal". You may need to buy the nuts and bolts separately. I say generally, because I've occasionally seen oddball equipment.
Some racks will have tapped screw holes, I've seen several difference screw sizes in the past. I always seem to have the wrong screw size handy too.
Many rails designed for square hole, will not fit in tapped hole racks. Most rails for tapped screw holes will work with square holes racks.
I can't tell from the supermicro rail kit (on ebay, or their website) as to what kind of rails they use.
Rails are tricky things. I suggest.. that for the time being, you buy some rack shelves. They're more versatile, and you can always just rest the server on the shelf.
It looks like the server and the rails come from the same seller, so perhaps the smart play would be to email him/her and ask?
