Rail Kit Install Guide: Intel® Modular Server System MFSYS25 5
Installing Rack Rails into Rack
9. For all four rack uprights, determine the vertical position in the rack at which the rack
rails are to be installed. The top-most mounting hole for a particular rack unit (RU)
mounting position is typically identified by a mark or hole.
Figure 4. Determining Vertical Position in Rack
Caution: If rack rail is mounted in holes which are not vertically aligned from front to back, the
rack rail may be damaged and rack mounting will not be secure.
10. Noting the holes determined in the previous step, align the left rack rail with its rear
mounting holes.
Note: Rack rails and multi-pin adapters occupy exactly 3 RU. The lowest point on an adapter is
eight (8) holes lower than the top-most mounting hole.
11. Hold the rack rail in the desired rack-mounting position. Engage the lowest pin in its
hole on the rack upright. At the rear of the rack rail, press and hold the top (floating)
pin downward while pushing the rack rail and adapter into the rack upright holes.
