You might need to install the system into a rack. Use the procedure in this section to perform this task. In addition to information intended to promote safety and reliable operation, this section also includes illustrations of the related hardware components and shows how these components relate to each other.

This is a customer task. You can perform this task yourself, or contact a service provider to perform the task for you. You might be charged a fee by the service provider for this service.

Important: To complete this procedure, it is suggested that you use two people to attach the rail assembly to the rack, one in front of the rack and one at the back of the rack. You will need three people to lift the system unit onto the rack.
