Routing cables using the CMA
About this task
Routing of power and data cables for the JBOD is integral to successful rail kit installation and rackmount
installation of the enclosure. Cables must be correctly installed and routed to facilitate efcient operation
and in-rack servicing of the enclosure.
This procedure describes the routing of cables through the CMA, including using the CMA baskets and the
CMA storage shelf located at the rear of the enclosure.
Procedure
1. Install the data cables and route them through the CMA brackets.
a) Rotate the CMA cable capture arms so they are out of the way of the data cable routing.
b) Route data cables 1–5 onto the CMA shelf and through the CMA brackets in the order and
conguration shown below.
c) Secure the routed cables with one hand, while installing additional cables until data cables 1–5 are
installed.
d) Rotate the outer cable capture arm close over data cables 1–5, ensuring it seats in the C-flange in
between the two cable capture arms.
Note: This model of the Disk Enclosure does not contain an IOM in slot 1. Thus, disregard the red
cables in the gures below.
