If two Rectifier Modules are installed in the shelf and one fails, the CBA1048 and Fan Tray (if installed) continue to operate normally. The failed Rectifier Module can be removed from the CBA1048 Rectifier Shelf and replaced while the power is on. Once the failed Rectifier Module is replaced, DC power redundancy is restored to the system.
The CBA1048 Rectifier Shelf has two slots for slide-in Rectifier Modules and a standard IEC AC input power connector for each slot on the rear panel. AC input power for each slot passes through a line filter inside the shelf. DC output power from each Rectifier Module passes through a ferrite bead on the way to separate DC output connectors on the rear panel of the Rectifier Shelf.
