8.4 Replacement of Controller
If a controller becomes defective, the SERVICE LED on the array controller lights orange. In addition,
the FAULT LED on the controller lights orange. The defective controller may be replaced with anew
one with the power of the disk array unit remaining ON.
If a cache memory or DE port installed in the controller becomes defective, the SERVICE LED on the
relevant array controller and the FAULT LED on the controller are lit.
If so, replace all the cache memories and DE ports as well as the controller or contact your
maintenance service representative to identify the defective unit for replacement.
<Replacement procedure>
1.
Identify the defected controller with the FAULT LED on the controller being lit.
Remove all the cables connected to the defective 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, open the ejector pulling it by 90º,
and then pull out the controller. (When the controller is pulled out, the protection shutter in
the unit closes and it is locked.)
Be careful this may be hot.
