Install the disk enclosure so that the ventilating holes may not be blocked. If either or both of the ventilating holes are blocked, the internal temperature of the disk enclosure may increase to cause a fault to occur.

The disk enclosure is equipped with 4 fans in total. Even if a fan fails, the air-cooling conditions for the entire disk enclosure are satisfied. However, to guarantee the safety operation of the disk array unit, replace the power supply for disk enclosure as soon as possible. Replacing the defected fan means that two fans are stopped, therefore, perform the replacing work within three minutes.

(4)POWER GOOD LED (green)

The POWER GOOD LED is lit green when the AC power is supplied to the additional 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 goes on if a fault occurs in the power supply (including fan fault). The LED is off while the power supply operates normally.

(6)Power cord stopper

The power cord stopper prevents the power cord from being removed unexpectedly.

(7)Ejector

The ejector is used to install or remove the power supply from the additional disk enclosure. Loosen the screw before using the ejector.

When inserting or replacing 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.
