Redundant Power Supply
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.
