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 failure” 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 steps to replace a failed power supply.
