Installing the expandable rails and extension bracket into the rack
You might need to install rails into the rack. Use the procedure in this section to perform this task. In
addition to related safety information, this section also includes illustrations of the related hardware
components and shows how these components relate to each other.
Attention:
Installing the rails in the rack is a complex procedure. To install the rails correctly, you must
perform each task in the following order. Failure to do so might cause rail failure and potential danger to
yourself and the system unit.
To install the expandable rails into the rack, complete the following steps:

2. Starting at the back of the rack, extend the left rail and insert the rail pins (C) into the marked
locations the rack so that it is facing upward (L shape).
Tip: Although the rail installation can be completed by one person, for ease of installation, one
person can be positioned at the front of the rack and one person at the back of the rack.
3. From the back of the rack, extend the right rail and insert the rail pins (C) into the marked locations.
4. Move to the front of the rack, extend the left rail and insert the rail pins (C) into the marked
