Attaching The Front Rail With The Screw - Dell DD9500 Manual

Figure 12. Attaching the front rail with the screw
3. Attach the small adapter to the rear of each rail using M5 screws.
4. At each rack post, determine the vertical position in the rack where the 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. Racks may also be screen-printed to
show the positions of the rack units.
NOTE:
● To comply with Data Domain rack mounting guidelines, the system controller should be installed in the pre-defined
space in the rack for system controllers. Refer to the Installation and Setup Guide for your system.
● Two people may be required to attach the rail/bracket assembly to the rack.
5. Install the screws supplied in the adapter kit to the rack. For example, the 10-32 threaded hole rack would require the
installation of the 10-32 screws. Install the screws in the appropriate locations until they are tight against the rack.
6. As needed, select the bracket marked right or left. Orientation assumes you are facing the front of the rack.
7. Slide the adjustable part of the bracket partly open.
8. Attach the first rail to the rack as follows:
a. Hold the rail against the inside of the rack with the rear bracket flush with the rear of the rack. Use the screws threaded
into the rack to hold the rear of the rail kit in place.
b. Pull the front of the rail until it is flush with the inside of the rack front.
c. Attach the rails to the rack by installing the appropriate nuts onto the screws threaded into the rack. Use the supplied
wrench to tighten the nuts. Do this for the front and rear of the rail kit.
d. Attach the rear of the rail/bracket assembly to the rear of the rack. Secure each screw.
