Ensure the system is running the appropriate firmware version to handle module removal and insertion without triggering a processor fault.\u003c\/p\u003e\n\u003cp\u003eQ: How is the redundancy synchronized between two racks?\u003c\/p\u003e\n\u003cp\u003eA: Redundancy is managed by the HC900 controller modules via the rack interconnect cables. Ensure that all redundant cable paths are installed and terminated correctly to enable bumpless transfer between primary and secondary processors.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Secure the rack assembly to a standard industrial enclosure using the integrated mounting points.
