6.4 REPLACING A RECTIFIER
In the event of rectifier failure, replace the unit. There are no user-serviceable parts in the rectifier.
A rectifier is identified by a label in the bezel recess and on the rear of the rectifier. Be certain you are
installing the correct model rectifier. Only 48V/50Amp rectifiers (UNIPOWER p/n 100.7675.4850) are
available with the Sageon 200A system.
To replace a rectifier, refer to Section 2.13 Installing and Removing rectifiers.
6.5 REPLACING THE SAGEON 200A CONTROL UNIT (SCU)
In the event of SCU failure, replace the assembly. There are no user-serviceable parts in the SCU.
The Sageon 200A SCU can be hot-swapped. Be certain a replacement SCU is on hand before beginning
this procedure.
6.5.1 Configuration Considerations
The system configuration is stored in non-volatile memory on the SCU backplane board. The SCU plugs
into the SCU backplane board so the SCU can be replaced without affecting the configuration.
