Prisma HDRx Reverse Path Receiver Platform Redundant Powering 

78-741702-01 Rev C 

As shown in the illustration below, the redundant fan/power supply unit should be 

mounted between two Prisma HDRx chassis’ and connected using two HDRx 

interconnect power cables, part number 734451.  If only one HDRx frame is installed 

in a rack, then the redundant power supply unit should be installed above the 

Prisma HDRx chassis.  The redundant power supply unit is capable of powering one 

HDRx frame at a time.  This provides an adequate level of redundancy since it is 

unlikely that both power supplies will fail at the same time.
