Introduction
This application note describes how the Prisma
HDRx Reverse Receiver Platform

Prisma HDRx Installation
The Prisma HDRx platform consists of a 4 RU high chassis that can be mounted in a
19- or 23-inch rack. The unit can be mid-mounted for installation into a fiber
management frame or front mounted for installation in a standard equipment rack.

module. Powering redundancy is provided by an external 1 RU rack-mount power
supply that also contains a fan unit to provide additional cooling.
