Cascading DAS Connection
If you are using multiple J610s or J310s units and want to manage them from the 
same SAS HBA card, connect the J610s or J310s units in a cascade. 
Connect the SAS HBA card in the Host PC to the subtractive-routed port (CN2)    
of the I/O module. Use a SFF-8088 4X to 4X external SAS cable (supplied with 
the J610s or J310s unit).
Connect the I/O module’s table-routed port (CN1) on the first J610s or J310s unit 
to the subtractive-routed port (CN2) on the next J610s or J310s unit.
You can cascade up to four J610s or J310s units in this manner. You can mix 
J610s and J310s units in the same cascade.
