Disclosed is a cable chain return system 100 that includes a spring 170 for assisting folding and organization of a cable chain 110. When a customer replaceable unit (CRU) 210 is extended from a chassis 140 to gain access to connectors on the back of the CRU 210, the cable chain 110 is extended. When the CRU 210 is moved back into the chassis 140, a plurality of folding curves 130 organize the cable chain 110, and cables 118 therein, without damaging the cables 118 or inhibiting positioning of the CRU 210 in the chassis 140. One of these curves 130 is initiated by the spring 170 and therefore aids in returning and organizing of the cable chain 110.
