Replacing a Power Supply

Each power supply in the Xserve RAID system is hot-swappable, so you can safely replace the unit while the system is operating. When one power supply has been removed from the system (or has failed), the other one provides power for the entire system.

Important When you remove a power supply from the system, be sure to replace it with a working power supply as soon as possible to prevent the drive modules from overheating.
