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 X failure”, where X indicates the power
supply 1 or 2.
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.
Note
To turn off the audible alert, simultaneously press the Up and Down
buttons on the front panel twice.

RAID systems.
