Rack mount confusion
Posted on 2011-10-20
I have purchased, from a friend's employer who is liquidating their server farm, a rack-mounted server. I don't have the item yet, but am getting my rack and accessories ready.
So I bought a 12u Kendall Howard wall-mounted rack. It's the standard 19 inches wide and it's 18 inches deep. It has lots of threaded holes on the front vertical rails for mounting servers & accessories, but none on the back.
I go to mount my rack-mount keyboard/LCD unit (courtesy of Ebay) ... and it has ears on the front and the back ... and it is 25 1/2 inches deep. So it won't fit.
And I'm looking at a Tripp Lite UPS and it is listed as 21.5 x 15 x 7.5 ... but a 2U device. So it won't fit and 7.5 inches is more like 4U than 2U.
Did I buy a junk rack? Or is the xU standard not a standard at all?
Thanks for any help!
