Abstract: A node comprises an FSP, a first FRU, a second FRU, and a controller. The FSP has a first connector having first port pairs and a second connector having second port pairs, a second port pair is optically coupled to at least one first port pair. The first FRU has third port pairs and a third connector coupled to the first connector. The second FRU has fourth port pairs and a fourth connector coupled to the second connector. The controller comprises a processor and a memory storing an FSP map and instructions, including: receive a first association between a third port pair and one of the first connector and the second connector; validate the first association; generate an FRU map based on the first association and the FSP map; update a mode type for each second association; receive a service activation request; and cause an FRU to activate the service.
