More Information

Overview Manuals Single-Mode Link HA Operation Replicated Data PCI Setup

Features:

  • Extends single-mode reflective-memory links to the supported 10 km distance.
  • Creates a direct two-node optical path for RX3i CPU redundancy.
  • Replicates configured network address regions without CPU-managed copying.
The single-mode transceiver distinguishes IC695RMX228 from the multimode RMX128 when plant distance or installed fiber determines the selection.

In a dedicated redundancy path, the primary and secondary units form a closed LC fiber ring with no hub or extra reflective-memory node.

A general reflective-memory network may contain many compatible nodes, but mixed optical media requires a compatible hub that preserves the required optical conversion and ring path.

General Electric IC695RMX228 PACSystems RX3i 128 MB Single-Mode Redundant Memory Xchange Module is available for Apter Power quotation and official-documentation support.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

IC695RMX228 Single-Mode Optical Path

  • Reach: Use the specified single-mode fiber for links up to 10 km.
  • Polarity: Connect each LC transmitter to the receiver of the next node in the ring.
  • Mixed media: A compatible hub is required only when a general reflective-memory ring combines single-mode and multimode nodes.
  • Connector care: Keep LC end faces capped, clean, and within the permitted bend radius.

IC695RMX228 Redundancy Link Rules

  • Pairing: A CPU redundancy path uses one RMX228 in the primary unit and one in the secondary unit.
  • Topology: The redundancy path is a direct two-node ring with no hub or additional reflective-memory node.
  • Link count: Emerson recommends two independent redundancy links when the system architecture permits four RMX modules.
  • Transfer mode: Optional redundant transfer sends protected network traffic to reduce the chance of a dropped packet.

IC695RMX228 Replicated Memory Operation

  • Propagation: A write at one compatible node updates the corresponding address at every node in the reflective-memory ring.
  • Packet sizing: The module selects transfer packets dynamically from 4 to 64 bytes.
  • Address segmentation: Configurable offsets assign nodes to 16 MB regions of the network address space.
  • Events: Four network interrupts carry 32 data bits each, in addition to the programmable module interrupt.

IC695RMX228 Main-Rack Integration

  • Bus location: The module requires a PCI position in an RX3i Universal Backplane main rack.
  • Rack population: A main rack accepts up to six CMX/RMX modules in total, with no more than two configured as redundancy links.
  • Power calculation: Include 580 mA at 3.3 VDC and 220 mA at 5 VDC in the rail-by-rail load check.
  • Powered service: Follow the RX3i hot-insertion sequence and grounded ESD procedure before handling the optical housing.
Description
IC695RMX228 uses single-mode LC optics to carry deterministic reflective-memory traffic over an RX3i redundancy network.

Its 128 MB SDRAM exchanges automatically sized packets across a configured ring of as many as 256 reflective-memory nodes.

Four general-purpose interrupts, programmable module events, memory offsets, and network-error monitoring let the single-mode module coordinate high-availability controller data.

Install IC695RMX228 only in the main RX3i Universal Backplane PCI bus; budget 580 mA at 3.3 VDC and 220 mA at 5 VDC and use grounded ESD protection around the LC optical assembly.

Technical notes
The single-mode IC695RMX228 optical network must use compatible LC fiber components; its installed hardware and firmware release must remain within the compatibility table for the selected RX3i CPU.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why does a long IC695RMX228 optical link remain open after installation?
For IC695RMX228, verify single-mode fiber, LC transmit-to-receive polarity, connector cleanliness, bend radius, and that the total path stays within the supported 10 km limit.
Can IC695RMX228 share a ring with multimode reflective-memory nodes?
For IC695RMX228, a compatible hub is required to introduce a single-mode node into a mixed-media reflective-memory ring; do not substitute patch cords alone.
Can an optical hub be placed between the two IC695RMX228 modules in a redundancy pair?
For IC695RMX228, no. The redundant CPU link must be a direct two-node ring; hubs and additional reflective-memory nodes are not permitted in that path.
Why does the IC695RMX228 ring open after one module is replaced?
For IC695RMX228, recheck the TX-to-RX daisy chain, node configuration, network memory offset, and redundant-transfer settings before returning the link to service.
How many nodes can use IC695RMX228 in a reflective-memory network?
For IC695RMX228, reflective-memory operation supports up to 256 compatible nodes, while a dedicated CPU redundancy link is restricted to its two RMX modules.
Can IC695RMX228 be installed in a serial expansion backplane?
For IC695RMX228, no. Install it on the PCI bus of an RX3i Universal Backplane and include its 3.3 VDC and 5 VDC current in the rack calculation.
What handling precaution applies to the IC695RMX228 optical assembly?
For IC695RMX228, use grounded ESD protection, keep the LC ports capped when disconnected, and remove contamination with an approved fiber-cleaning method.
