Removing a single CHARM triggers a localized open-circuit diagnostic alert in the DCS interface but maintains live operation and network integrity across the remaining 95 active channels.\u003c\/p\u003e\n\u003cp\u003eQ: What is the mechanical switching latency when the secondary network interface assumes the communication load during a primary link failure?\u003c\/p\u003e\n\u003cp\u003eA: The card features a deterministic, fully redundant physical bus architecture. A hardware-level link degradation triggers a bumpless failover sequence to the secondary communication rail within milliseconds, preventing active data frame drops.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrounding Rail Bonding:\u003c\/strong\u003e Mount the unit firmly onto standard structural DIN rails.
