What is Fault-Bus? Why the Need for Fault-
Bus?
Fault-bus is a proprietary enclosure management interface. It gathers
the failure signals from the cooling fans, redundant power supply,
enclosure temperature sensor and UPS device. It reports these failure
information to the user through the front panel, RS-232C terminal
interface and Acer RAID Manager . The LED of the drive that failed will
light showing the location of the drive that needs to be replaced. It
warns the user of a dangerous situation happening to the RAID
subsystem.
