The Dell PowerEdge R710 is a 2U Rackmount Server that uses the new Dell Ready rail kit. The rails themselves no longer attach to the rear mounting surface of the rack post but now wrap around and attach to the front mounting surface. The square hooks that Dell has used for years on their rail kits have been replaced by a set of pins and a small safety latch. This fully sliding replacement rail kit offers all of the same benefits as the Dell rail with an increased mounting depth range.
