Rack Door That Will Function as a Cable Management Arm

To create large rack-mounted server systems, smaller systems are sometimes linked together by cables. These cables are both thick and stiff and have a large bend radii of 4 to 6 inches. If the cables linking the systems are at the front of the rack, then with current rack designs it would be impossible to close the door of the rack. In a data center environment, not being able to close the door, or having to remove the door would be unacceptable to many customers.

Cables are routed from the front of a server into the back of a specially designed rack door. They are passed round a vertical rod and then through a gap in the central bulkhead. From there they are routed to the level of the next server in the rack, back through another gap in the central bulkhead, around the rod, and so to the connection point on the next server, This routing ensures that a service loop exists so that when the door is opened or closed, undue strain is not placed on the connector plugged into the server. It also ensures that cables are contained within the volume of the door and are controlled when the door is opened.

A second advantage is that it automatically moves cables out of the way when the system requires servicing.

A third advantage is that the cables can easily be labelled and tied off to the correct lengths so that there is no confusion when cables are...
