For instructions for stabilizing the rack, refer to
Server X7-2 EF and HC Installation
at https://docs.oracle.com/cd/E85660_01/index.html.

Although the cable management arm (CMA) that is supplied with the server is hinged to
accommodate extending the server, ensure that all cables and cords are capable of extending.

in the open position.
When in an open position, the release latch covers engage the slide-rail release latches [1].
Deploy any rack anti-tilt mechanism before releasing the slide-rail release latches.
