HP Universal Rack Mount Kit (with Stop Feature) for 19-23 in. 2- and 4-Post Racks Installation Instructions 4. Install the outer rail subassemblies into the rack using ten or twelve (19" or 23" kits, respectively) 1032x1/2" SEMS screws. If bar-nuts are used, they should be installed such that all threads are aligned vertically, ensuring the center hole is not skewed with respect to the holes on the rack rail. NOTE If mounting a 1U system in a 1U confined space, four 2U bar-nuts are included to replace the 1U bar-nuts. The 2U bar-nuts need to be installed in the 1U space either above or below the 1U space where this kit is being mounted. When installing multiple 1U systems, the 2U barnuts should be used in the next to last kit. NOTE L-Brackets should be adjusted front-to-back to fit rack depth. The distance between the front equipment mounting rail and rear equipment mounting rail cannot exceed 24 inches. Figure 1-6. Installing the Outer Rails 8
