Installing a 3U disk enclosure (DAE) in a cabinet
Figure 44 Securing the rear of the enclosure
2. Once the enclosure is completely seated into the rear tabs, tighten 
the four screws (two on each rail) that secure the rails to the front 
channels. 
3. Secure the front of the enclosure to the front vertical channels of 
the cabinet using four M5 12.7 mm
 screws (two per side), as 
shown in Figure 45.
Note: The front screws also help to secure the latch bracket mounted on 
the front of the enclosure. 
If you are installing the enclosure in a NEBS-compliant environment, 
secure the unit to the front channels with the four shape thread rolling 
screws supplied with your installation hardware in part number 
100-560-644.
