Replacing a Power Supply
The disk array system is equipped with a Power Supply Fail Indicator LED at the front of
the unit that turns red when one of the power supplies fails. The message “Power x fail-
ure” also appears on the LCD panel, where x refers to power supply 1, or 2, and an
audible alert sounds.
Power supplies are hot swappable, which means that they can be inserted and removed
while the disk array is powered on and operating. Follow these instructions to replace a
failed power supply.
1
Identify the power supply that has failed.
2
Remove the power cable from the power supply connector at the rear of the unit.
Note
Turn off the audible alert by pressing the Up and Down function but-
tons on the front panel twice simultaneously.
Note
The system is equipped with auto switching power supplies that
can run on 100 to 240 VAC.
