The Dell PowerEdge R210 and R240 are known as “short depth servers” and we designed a rail to capitalize on that fact. Dry slide rails designed for full length servers typically have excess inner rail in the back. Since the R210 and R240 are shorter servers, the inner rails of this kit can be shortened so that they will fit within low depth racks. A flush mount kit (opens in a new tab) is required for flush mount rail installation. The conversion brackets must match the corresponding rail’s U height (e.g., 1U rail = 1U Conversion Bracket).
Unlike OEM Dell rails, these will work with square, round or threaded hole racks out of the box. It also can be converted between 2 post and 4 post and four post mounting orientations. The rail is made from 18 Ga galvanized steel for long lasting, high quality experience.
Inner rail protrudes on the 122-2579 (Cobra 79)
Inner rail stays within outer rail on the 122-7650 (Cobra 50)
