In FIG. 16, in the LED lighting system 20, a break in the circuit appears and is detected between the DRV 361 and the OS 37. There also appears to be a break in the circuit between the DRV 362 and the OS 37. As long as no break between the power source PS 10 and the input selector IS 35 is diagnosed, the MCC 38 sends a message instructed the IS 35 to connect to a different spare DRV,DRV 363 from plurality of the DRV available (361,362, 363) and, the MCC 38 send a message and will instruct the OS 37 to connect to a LLS 401 from plurality LLSs (401,402,403) creating a new pathway PPW 7:
In FIG. 16, the DRV 361,362 where detected to be non-functional or defective, the next spare DRV 363 was replaced the initially selected DRV 361,362 respective, to ensure LED lighting system 20 good operation and creating a new PPW 7:
PS 10>IS 35>DRV 362>OS 37>LLS 401
FIG. 17 shows an example LED lighting system 20 in the topology 1, 3, 3 (1 PS 10×3 DRV 36 (361 and 362 and 363)×2 LLS 40 (401 and 402 and 403) commutation policy ending configuration LLS 402 connected to PS 10 through DRV 363.
