You can replace a failed power supply while the bus node is operational, provided that the remaining supply is capable of handling the current load and the unit is correctly seated.\u003c\/p\u003e\n\u003cp\u003eQ: How is the redundant bus communication verified in the CENTUM VP software?\u003c\/p\u003e\n\u003cp\u003eA: The system software continuously monitors the heartbeat signals of the dual ESB bus interfaces. Any discrepancy in data packet arrival times or loss of signal on one bus will trigger a diagnostic alarm in the Human Interface Station (HIS), indicating a fault in the primary or secondary bus path.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMounting:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eInstall the unit in a standard 19-inch cabinet rack using all four mounting points.
