4. Product Introduction & Supply Chain Strategy
The GE Fanuc IC698CRE040-HN is a premium 700 MHz Pentium III central processing unit designed to execute high-availability hot-standby redundancy within the PACSystems RX7i mainframe framework. Featuring two onboard fiber-optic synchronization ports, this module connects directly to a secondary standby chassis to enable real-time tracking of memory registers and internal status matrices twice per logic sweep. Coupled with a 64 MB user memory area and a three-port embedded Ethernet switch, it delivers bumpless control transfer during critical failover events.
From a vendor management perspective, the “-HN” revision of the IC698CRE040 is a high-impact, low-turnover asset that protects mission-critical applications. Because the RX7i series is obsolete, a sudden failure on a primary process node risks a plant blackout. Choosing third-party refurbished processors introduces severe operational risks due to thermal stress on the internal VME64 transceivers and aged cache capacitors. Sourcing this module as a factory-sealed New Surplus asset establishes a predictable Total Cost of Ownership (TCO), ensuring your maintenance teams have a zero-hour backup card ready for direct insertion while long-term control upgrades are scheduled.

5. Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
Enforce complete lock-out/tag-out (LOTO) protocols across the targeted RX7i baseplate rack and isolate all external field communication loops. Wear a grounded ESD wrist band connected directly to the bare metal chassis frame. Connect an engineering workstation to the active controller node, then perform a complete project backup, register table export, and hardware topology upload within Proficy Machine Edition.
Stage 2: Removal
Unplug the active serial cables and fiber-optic synchronization lines from the front faceplate, noting the specific channel assignments. Disconnect all network cables from the three RJ-45 ports. Loosen the upper and lower faceplate retaining screws. Pivot the top and bottom extraction levers outward simultaneously to break the high-density mechanical friction seal of the VME64 backplane pins, then pull the processor card out horizontally.
Stage 3: Installation (Clone & Seat)
Verify that the replacement IC698CRE040-HN has clean backplane contacts and that its rear configuration jumpers match the original module layout. The primary controller must always reside in Slot 1 of the main rack. Slide the module smoothly along the upper and lower plastic chassis tracks, then lock the top and bottom ejector clips to seat the module firmly into the VME64 backplane interface. Tighten the faceplate retaining screws and reattach all serial, network, and fiber-optic synchronization cables.
Stage 4: Power-On & Testing
Energize the RX7i main rack power supply rail. Monitor the front-panel status cluster: the “OK” and “RUN” indicator lights must turn solid green after completing the baseline boot diagnostics. Open Proficy Machine Edition, clear the historical CPU error log, download the verified logic backup, and confirm that the synchronization status transition completes successfully to put the paired standby chassis into active redundancy tracking.
6. Firmware/Software Versions & Upgrade Notes
The IC698CRE040-HN requires rigid firmware matching to achieve stable hot-standby synchronization handshakes.
- Software Requirements: Setting up and managing this module requires Proficy Machine Edition version 5.50 or higher.
- Firmware Parity: The primary and secondary CRE040-HN modules must execute the exact same firmware revision down to the minor build number. A mismatch will break the link, causing the system to fall back into simplex operation.
- Upgrade Risks: Do not pull an IC698CRE040-HN out of storage and insert it into an active production rack without checking its chip revision number. If the replacement card carries an older firmware revision than the original module, it can cause logic compilation errors, drop communication with high-density analog modules, or lock the CPU into a continuous configuration fault. Always verify and match firmware versions on a test rack before commissioning the card.
7. Frequently Asked Questions (FAQ)
What does the “-HN” suffix mean on this IC698CRE040 part number?
The “-HN” suffix designates the specific hardware revision level and manufacturing build flight at the time of OEM assembly. It indicates the component arrangement on the internal circuit board and specifies compatibility parameters within the hardware catalog of Proficy Machine Edition. It is fully interchangeable with systems running matching application profiles.
Is this processor a genuine new unit or a repaired card?
This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability. Every processor is stored within sealed anti-static protective packaging, showing pristine gold edge connectors and zero track adjustments.
Can I run this processor as a standalone unit without a redundant partner?
Yes, the IC698CRE040-HN can run in simplex mode within a single rack configuration. If the secondary standby partner is absent or experiences a hardware stop, the primary unit executes all logic blocks independently. However, to leverage its full hot-standby capabilities, you must install a matched partner processor, twin racks, and fiber synchronization links.
How does this module maintain its user logic during a complete power loss?
The IC698CRE040-HN utilizes a combination of volatile CMOS SRAM backed up by a lithium battery pack mounted on the main rack power supply, and an internal non-volatile Flash memory bank. During normal shutdowns, the battery loop maintains the live register data. For permanent security against long-term power blackouts, you should compile and save a master copy of the application code directly to the onboard Flash memory via Proficy Machine Edition.
What kind of warranty coverage applies to this surplus CPU?
Every New Surplus IC698CRE040-HN unit comes backed by a comprehensive 1 -year operational warranty. If a component defect occurs during this window, we handle replacement or repair immediately, shielding your operating budget from the limited 30-day structural warranties typically packaged with refurbished alternative components.
