8.4 Fault of Power Supply for Disk Enclosure
If the power supply for the additional disk enclosure is defected, the SERVICE LED on
the array controller is lit orange. In addition, the SERVICE LED on the additional disk
enclosure in which the defected power supply is installed and the POWER FAULT LED
on the defected power supply are lit orange.
The defected power supply for the disk enclosure may be replaced with the powers of the
array controller and additional disk enclosure remaining ON.
When replacing a power supply for the disk enclosure, prepare the new
power supply before removing the old one, and then replace it within about 3
minutes.
The following are heating units of the disk enclosure:
A) Disk drives
B) Power supplies for the disk enclosure
The fans in the power supplies for the disk enclosure serve as cooling fans
for both of the above. Therefore, do not leave the disk enclosure with one of
the power supplies removed. Doing so causes the disk drive temperature to
rise, which may significantly decrease the reliability.
<Replacement procedure>
(1) Turn off the power switch of the defected power supply for the disk enclosure.
Push down the power cord stopper (for the power cord) toward the left, release the
power cord stopper from the receptacle of the power cord, and then remove the
power cord.
