(4) POWER GOOD LED (green)
The POWER GOOD LED lights green when the AC power is supplied to the disk
enclosure and the power switch is set to ON. The LED is off if the power switch is
set to OFF or a fault occurs in the power supply.
(5) POWER FAULT LED (orange)
The POWER FAULT LED lights if a fault occurs in the power supply (including fan
failure). The LED is off while the power supply (including fan) operates normally.
(6) Power cord stopper
The power cord stopper prevents the power supply from being removed
unexpectedly.
(7) Ejector
The ejector is used to install or remove the power supply from the disk enclosure.
Loosen the screw before using the ejector.
When inserting the power supply for the disk enclosure into the disk
enclosure, push it as far as it will go and then secure it with the screws.
Incorrect insertion may cause a power supply failure again.
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.
