CAUTION: Ensure the holes on the rail line up with the holes on the cabinet. This will ensure proper alignment of the rails. Also, check that the rails are level from front-to-back and left-to-right. Ensure you are using the same unit markers from the front of the cabinet to the rear of the cabinet. 6. Push in on the spring clip while pulling the rail forward. When the spring clip is forward of the front rack channel, and the adaptor is in the mounting holes, release the spring clip so it holds the rail in place. CAUTION: Ensure the spring clip is securely attached to the channel. It may be necessary to push in on the clip to assist in snapping it into place. Figure 18. Securing rail to front channel Installing the DAE on the rails About this task CAUTION: Do not install the enclosure without the rear rail screws installed and fully tightened.
