How to setup one Dell EMC AX4-5 Dual Controller System from two AX4-5 with Single Controllers

Hi,

A few years ago we bought two Dell EMC AX4-5 Systems with single controller. Meanwhile the Support ended. The performance of a Single Controller System is very slow. A new Hard disk cost around 1000€ by Dell-Customer-Support. We decide to use only one chassis, but with 2 controllers (one from the second system).

The Problem is our system don't detect the second controller we took from the other Single-Controller System. We couldn’t find any manual to set the DIP-Switches on the controller. Does anyone know how to setup a Dual-Controller-System with components from two single Controller AX4-5 Systems?
