Install rail brackets using the adapter hardware (for threaded hole racks)

About this task

NOTE
  • If you are using a rack with square or round holes, go to Install rail brackets on the Data Domain racks (for square or round hole racks) section.
  • Only use this procedure if your rack has tapped holes that are M5, M6, 10/32, or 12/24.
  • The adapter hardware is shipped in the rack mount kit.
  • You will need a long handled screwdriver with a shank diameter less than 7.0 mm and the wrench (included in the kit) to tighten the nuts.

Steps

  1. Locate the two adapters from the rail kit.
    Figure 1. Adapters
    • 1. Long adapter
    • 2. Short adapter
  2. Attach the long adapter to the front of each rail using M5 screws.

  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:
    1. 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.
    2. Pull the front of the rail until it is flush with the inside of the rack front.
    3. 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.
    4. Attach the rear of the rail/bracket assembly to the rear of the rack. Secure each screw.

  9. Repeat the steps for the second rail.
  10. After installing both rails, make sure that they are level with one another.
  11. For HA systems, repeat this procedure for the second node.
