Servicing Notes
An intermittent or complete loss of power to the controller modules, Battery Backup Unit,
or controller enclosure fan module may indicate either a defective power harness or power
interface board. If replacing the harnesses does not resolve the problem, you may need to
replace the entire power supply housing, which includes the power interface board.
