How to install the rails
Installation is fast and easy, and no tools are required to install the rails in your cabinet.
Prerequisite(s):  
Ensure you have all of the parts. Rail kit hardware
 
These steps assume you are at the front of the cabinet when installing. If you install appliances from the rear of your cabinet, such as for airflow reasons, the front of the rail must be closest to the face of the appliance for the slide locks to engage.
Rather than screws, ½ inch (14mm) posts on the rail known as locking pins fit into holes in the cabinet. A plastic tab known as a rail lock ensures the rail stays attached to the cabinet. If your cabinet requires screws, replace the locking pins with the provided screws.
1. If your GigaStor has a blue face plate, remove the existing slides and attach one plastic slide to each side of the appliance with the slide lock towards the front.
 
2. Identify the front of the rail kit.
The front is marked with FA near the finger pull on a label. The front of the rail should be closest to you when inserting the rails into your cabinet.

3. Expand the rail a bit longer than the length of your cabinet’s posts.
The rails should slide easily to expand. If it does not, loosen the thumb screws.
4. Insert the rear locking pins into your cabinet and pull towards you until the rail lock clicks into place.
Due to noise in your server room you may not hear it click. Also, the rail lock is small and you may not feel it catch.

To test that the rail is locked into place, gently push the rail away from you. If it stays in the cabinet, it is properly installed. If it comes out, reinsert the rail.
5. Insert the front of the rail into the cabinet.
Use the finger pull to shorten the rail. Like the rear, it also has a rail lock that secures the rail in the cabinet.
6. Tighten the thumb screws.
 
The rails are installed in your cabinet and ready to receive an Observer Platform appliance.
