Installing the rails in the cabinet

1. Orient the rails. Face the front of the cabinet when orienting the left and right rail placement. The front edge of each rail is stamped L or R.
2. From the rear of the cabinet, insert the adapters into the holes on the rear rack channel with the rail extended as shown in the following figure.

   

3. Push the rail into the rear mounting holes until the spring clips snap into place on the outside of the rear channel.
   CAUTION:To ensure proper alignment of the rails, ensure that:

   • The holes on the rail line up with the holes on the cabinet.
   • The rails are level and using the same cabinet Unit markers from front to rear.
4. From the rear of the cabinet, secure the rails in place using one M5 screw on each rail.

   

5. Working from the front of the cabinet, align the adapter with the mounting hole on the front of the rack as shown in the following figure.

   

   CAUTION:To ensure proper alignment of the rails, check that:

   • The holes on the rail line up with the holes on the cabinet.
   • The rails are level from front-to-back and left-to-right.
   • You use 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 adapter 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.
