b. If the rails are being installed in a non-EMC rack with threaded holes, insert the M4 screw into the smaller of the two screw holes. The screw will be smaller than the threaded hole and will pass through the threads. Installing the rails in a non-EMC rack CAUTION: Exercise care when installing the short rails. Exposed metal edges may be sharp and could damage cabling or cause injury to personnel. For each shelf, install the rails using the table, figure and steps that follow. The rails are designed to be universal in nature. They are shipped with 6.8mm adaptors that will fit into any EMC rack. To install the universal rails into a non-EMC rack, the 6.8mm adaptors must be removed, then replaced with rail pins that will fit the hole-types in the rack being used. The following table shows the rail pins and their suggested use . Page 11 of 33

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
