Failure of Power Control Card
If a power control card is defected, the SERVICE LED on the disk array unit lights orange. In addition,
the FAULT LED on the power control card lights orange. The defected power control card may be
replaced with the power of the disk array unit remaining ON.
<Replacement procedure>
1.
If the disk array unit containing a defective power control card is logically connected to the
host power control unit (online state), logically disconnect the disk array unit (offline state).
(For the method to change to the offline state, see the instruction manual provided with the
host power control unit.)
2.
Disconnect all the cables from the power control card. At this time, take notes of the
correspondence between the cables and connectors.
3.
Remove the screw that secures the power control card. Be careful not to lose the screw.
4.
Pull out the defective power control card forward, holding the upper and lower protrusions.
