If a controller is defected, the SERVICE LED on the disk array unit lights orange. In addition, the
FAULT LED on the controller lights orange. The defected controller may be replaced with new one
with the power of the disk array unit remaining ON.

Identify the defected controller with the FAULT LED on the controller being lit.
Remove all the cables connected to the defected controller. Write down the connections
between the cables to be removed and the mating connectors.
2.
Loosen a screw securing the ejector of the target controller.
3.
Put your finger on the protrusion of the ejector and pull the ejector toward you. Open the
ejector pulling it by 90º, and then pull out the controller.
Be careful that it is hot.
