Functional Features EZ customized redundancy firmware, dual‑CPU health monitoring, synchronization process control, bumpless switch‑over trigger, redundancy fault diagnosis, front‑panel LED status display.
Application Scenarios Project‑specific redundant system spare parts, RX3i high‑availability control cabinet requiring EZ firmware version.
Performance Parameters Rapid redundancy anomaly detection Reliable control authority switch‑over Shock & vibration:Comply with IEC 60068
Structural Characteristics Standard RX3i plug‑in rack module Front‑panel LED indicators for redundancy run and fault status Dedicated redundancy link interface terminals Backplane gold‑finger bus contact Internal redundancy processing circuit with EZ firmware Mechanical locking latch
Working Principle CRU320‑EZ interacts with primary and standby CPU via redundancy link and backplane bus. EZ firmware implements monitoring and switch‑over logic. When primary CPU fault condition is detected, module initiates switch‑over sequence, transfers control right to standby CPU and logs redundancy fault events.
Installation Requirements Mount into dedicated redundancy slot of RX3i redundant rack. Complete cabinet protective ground. Wire redundancy cables strictly follow hardware manual. Replace module only after rack power‑off. Guarantee cabinet ventilation heat dissipation.
Usage Notes Verify EZ firmware matching with paired CPU hardware. Periodically check redundancy cable connection. Judge system redundancy state by front‑panel LED. Forbid on‑site disassembly. Prevent corrosive gas and liquid splash.
