Use the following procedure to ensure that the slide-rails and CMA are operating correctly.
When the server is fully extended, you must release two sets of slide-rail stops to return the server to the rack:
The first set of stops are levers located on the inside of each slide-rail, just behind the back panel of the server.
The server slides in approximately 18 inches (46 cm) and stops.
Verify that the cables and the CMA retract without binding before you continue.
The second set of stops are the slide-rail release buttons, located near the front of each mounting bracket. Simultaneously push both of the green slide-rail release buttons.
