Routing cables using CMA

Routing of power and data cables for the 4U100 enclosure is integral to successful rail kit installation and rackmount
installation of the enclosure. Cables must be correctly installed and routed to facilitate efficient operation and in-rack
servicing of the enclosure.
4U100 is available in following 2 types of CMAs.
• Standard capacity CMA
• High capacity CMA
Selection of either of above CMA depends upon customer requirement.
Routing cables through the Standard CMA
IMPORTANT: This section provides instructions for routing cables through the Standard capacity and High capacity
CMA configuration, which include using the CMA baskets and the CMA storage shelf located at the rear of the enclosure.
Depending on your 4U100 enclosure configuration, power cables are routed either using an open lever and hinge
brackets (butterfly) mechanism or they are routed through two cable clamps. Photographs in this section shows CMA
shelf equipped with an open lever which holds power cables coming from left PSU.
