After replacement, download hardware configuration and perform redundancy synchronization and bumpless switchover validation test.

Environmental Specifications

‑ Operating temperature: 0 ℃ ~ +60 ℃ ‑ Storage temperature: ‑40 ℃ ~ +85 ℃ ‑ Relative humidity: 5%‑95% non‑condensing ‑ Installation location: Indoor control cabinet, IP20 protection class ‑ EMC compliance: IEC 61000‑6‑2 ‑ Certifications: CE, UL Class I Div 2 hazardous‑location certification

Mechanical Data

‑ Weight: approx 0.42 kg ‑ Dimension: RX3i single‑slot module form‑factor ‑ Handling note: ESD‑sensitive high‑speed fiber communication circuitry. Use GE‑qualified SFP transceivers. Observe correct TX‑RX cross‑connection for fiber cabling.

Main Functions

1. Dedicated high‑speed synchronization link for RX3i hot‑standby redundant system. Real‑time mirrors primary CPU runtime data to standby CPU via reflective‑memory fiber channel, ensures bumpless automatic switchover when active CPU fails.
2. When configured in CMX mode, implements deterministic peer‑to‑peer data exchange among multiple PACSystems controllers on reflective‑memory ring network, no CPU scan‑cycle overhead for memory replication.
3. Front‑panel LED indicators:   ‑ Green MOD OK: Module hardware normal status   ‑ Red NET FLT: Fiber link / network synchronization fault   ‑ ACTIVE: Reflective‑memory network operational   ‑ LINK1 / LINK2: Fiber port link and activity status

Installation & Wiring Requirements

1. Cut off full rack power supply for initial installation; hot‑swap replacement is permitted. Apply ESD protection during module handling.
2. Insert IC695RMX128 into single slot of RX3i universal main‑rack backplane and engage locking latch. Install compatible SFP fiber transceivers. Cross‑connect TX‑RX fiber cables between paired RMX modules for redundancy application.
3. Fiber wiring comply with GE RX3i manual GFK‑2511C. Observe transmit‑receive polarity. Reliable protective‑ground connection is required. Configure redundancy transfer‑list in Proficy Machine Edition for hot‑standby system.
4. After replacement: Power‑on rack power, check front‑panel LED status. Download hardware configuration and application project. Verify fiber link health, redundancy synchronization status and manual bumpless switchover performance.
5. Replacement note: Confirm host CPU firmware meets minimum revision requirement. Check fiber cable attenuation and polarity. Full‑system commissioning test is mandatory before putting into service.
