If you have a single controller FAS , it's a kind of cascade ending with the last shelf.
If you have a dual controller FAS , it's also a kind of loop-cascade but the last shelf will be connected to the second controller acp port
Ctrl1 1 --> shelf1 --> shelf2 --> ctrl2.
Details can be found in the DS4243 Disk shelf Installation and setup sheet or the Universal SAS&ACP cabling guide.
