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
l
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:
l
Mount node 0 such that the bottom of the chassis aligns with the 13U mark in
n
the rack.
Mount node 1 such that the bottom of the chassis aligns with the 18U mark in
n
the rack.
Procedure
1. 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.
2. As needed, select the bracket marked right or left. The rear of the bracket
contains an adjustable piece.
