4.3 Replacing a Power Supply
A failed power supply is indicated when:
•
the Power Supply (P/S Fail) LED indicator turns red
•
the audible alert sounds
•
the LCD displays “Power failure”.
Power supplies are hot-swappable, which means they can be installed and removed even while the RAID system is
powered on and functioning.
Follow the procedures below to replace a faulty power supply:
1. Identify the faulty power supply.
2. Detach the power cable from the power supply.
3. Loosen the screws of the faulty power supply.
4. To remove the power supply, press the release catch and
pull the handle at the same time.
5. Press the release catch and push with the handle at the
same time to insert the new power supply into the slot.
Note
To turn off the audible alert, simultaneously press the Up and Down buttons on the front panel
twice.
