Install rail brackets on the Data Domain racks (for square or round hole racks)
About this task
NOTE
- Do not hold the bracket assembly in a vertical position as the parts may separate.
- If you are using a rack with threaded holes, skip this section and go to Install rail brackets using the adapter hardware (for threaded hole racks) section.
- The Data Domain system is 4 rack units (RU) tall so make sure the location in the rack fits the product. Attach the bracket assembly to the lowest RU of the 4-RU opening.
- 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.
- For HA systems:
- Mount node 0 such that the bottom of the chassis aligns with the 13U mark in the rack.
- Mount node 1 such that the bottom of the chassis aligns with the 18U mark in the rack.
Steps
- At each rack post, determine the vertical position in the rack where the brackets 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. The bracket will be installed in the bottom hole of the 4 RU opening.
CAUTION If the bracket is mounted in holes that are not vertically aligned from front to back, the bracket may be damaged and mounting will not be secure.
- As needed, select the bracket marked right or left. The rear of the bracket contains an adjustable piece.
- From the rear of the system, hold the bracket against the inside of the rack posts. Align the rear guide pin and slide the bracket towards the front. The guide pins can help to temporarily hold the rack mount bracket in place. Attach the bracket to the rear of the rack using the furnished screws. There are five screw holes. The picture shows two screws attached to the rear rack post.

CAUTION If the bracket is mounted in holes that are not vertically aligned from front to back, the bracket may be damaged and mounting will not be secure. - Pull the adjustable sliding part of the bracket towards the front until it is close to, but not touching, the front of the rack.
Figure 2. Insert screw in the front 
- Attach the front of the brackets with two screws each in the two middle holes (innermost holes) as shown in the picture.

- Verify that the bracket is level.
- Repeat the steps to attach the remaining bracket to the other side of the rack.
- After installing both brackets, make sure that they are level with one another.
