Controller Module of JBOD Models
The expansion JBOD controller features SAS expansion ports (1), SAS expansion
port status LEDs (2), controller status LEDs (3), extraction levers and retention
screws (4).
The expansion controller contains a circuit board within a metal canister, interfaced
through hot-swap docking connectors at the back-end. Two SAS wide ports on the
interface faceplate
connect to a managing RAID system or other JBODs.
WARNING
The only time you should remove the controller is to replace a failed controller. The
controller is built of sensitive components and unnecessary tampering can damage
the controller.
