1.4 Routing the Cables Through the CMA
You can install the CMA on either the rear right or rear left side of the rails. Mounting the CMA on the
side that is opposite of the power supplies (left-side mount) is recommended; otherwise, the CMA
must be disconnected, to some extent, in order to remove the power supplies. Refer to Section 3 for
details on power supply replacement.
