Rectifier Modules are installed into the CBA1048 Rectifier Shelf from the front, after removing the front panels. The Rectifier Modules have a PCB edge extending about a half inch from the Rectifier Module rear panel that engage edge connectors at the back of the slot when the Rectifier Module is fully inserted.
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.
