Follow these steps to install your DPE. The DPE should be installed just above the SPS. The 
rails must be aligned carefully. A hole in the cabinet channel above the SPS remains open. Two 
people are recommended to install the rails.
1.  Insert the adjustable 3U rail slide and seat both alignment pins into the rear channel of 
 your cabinet. 
2.  Extend the adjustable rails so that it extends to the front channel of the cabinet.
3.  Align the front of the rails carefully as shown. 
4.  Insert two retention screws in the front and two retention screws in the back of each rail  
 as shown. 
5.  Tighten the screws once the rails are aligned correctly.
