NOTE: 5U84 controller enclosures support dual-controller module configuration only. If a partner controller module fails, the
controller will fail over and run on a single controller module until the redundancy is restored. Both controller module slots
must be occupied to ensure sufficient airflow through the controller during operation.
5U84 rear panel components
This section describes the rear-panel controller modules, expansion module, power supply module, and fan cooling module.
Controller modules
The 5U84 controller enclosure uses the same controller modules that are used by 2U12 and 2U24 enclosures.
