Figure 33: Ultrastar Data102 CMA Lite
The lite version of cable management assembly
(CMA Lite) provides the same cable management
and protection benefits as the standard CMA for a
lighter cable load (2 SAS, 2 power, 2 Ethernet). It
features modified cable and enclosure positioning
to allow the enclosure to fit within racks that utilize
front and rear doors.
CMA Lite manages the cables connected to the PSU
ports, SAS ports, and Ethernet ports by securing
them to an extendable arm with basket clips that
can be opened at the top to adjust, add, or remove
cables. The extension of the arm prevents damage
or unplugging of the port connectors and cables
throughout the full travel of the enclosure as it is
pulled out of the rack for servicing. The arm can also
be moved into a service position by unclipping it
at the elbow end and swinging it away from the
enclosure when the enclosure is fully inserted in
a rack. This provides access to connections and
components at the rear of the system without having
to remove the assembly or disconnect any of the
cabling.
