Installation & Configuration Guide
Phase 1: Pre-Installation (Estimated time: 20 minutes) ⚠️ Safety First:
- This is the “brain” of your Mark VI system. Replacing it requires a full system shutdown.
- Crucial: Ensure you have a current backup of the
.m6bor.m6pcontrol project files. - Verify the “H2AF” suffix. GE UCVE boards have different memory and processor configurations; using an “H1A” in place of an “H2A” can cause OS boot failures.
Phase 2: Removal (Estimated time: 10 minutes)
- Label Cables: Mark the Ethernet cables for U, V, and W IONet connections. Swapping these can cause redundancy loss.
- Ejector Handles: GE VME boards use specialized locking handles. Press the release buttons and pull the handles outward simultaneously to unseat the board from the backplane.
- Handle with Care: Once the board is out, place it immediately on a grounded anti-static mat.
- Remove CompactFlash: If the new board doesn’t have a CF card, you may need to transfer the card from the old board—but only if the old card is not corrupted.
Phase 3: Installation (Estimated time: 20 minutes)
- Inspect Pins: Look at the long 160-pin connectors on the back. Ensure no pins are bent.
- Slide and Seat: Slide the IS215UCVEH2AF into the rack slots. Use the injector handles to firmly lock it into the backplane.
- Connect Peripherals: Reattach Ethernet cables and any serial diagnostic cables.
- DIP Switches: In my experience, most UCVE boards are “plug-and-play” regarding hardware addresses, but verify that the DIP switches match the original board’s positions.
Phase 4: Power-On & Booting (Estimated time: 45 minutes)
- Apply rack power.
- Serial Monitor: Connect a laptop via the COM1 port (9600, 8, N, 1) to watch the BIOS and QNX boot sequence. This is the best way to catch errors early.
- Firmware Sync: The Mark VI toolbox will likely prompt you to “Download” to the new controller. This synchronizes the runtime code and hardware parameters.
- Redundancy Check: If in a TMR (Triple Modular Redundant) system, ensure the other two controllers recognize the new “sibling” and that the “Voted” status returns to normal.

Customer Cases & Industry Applications
Case 1: Critical Control Failure at a Gas Peaking Plant A power plant in Texas faced a total loss of the “U” controller on their Mark VI system. The original IS215UCVEH2AF had suffered a processor failure due to cooling fan exhaustion. Without the third controller, the system lost its “voting” integrity. We supplied a New Surplus unit from our stock within 48 hours. By replacing the board and performing a Toolbox download, the plant returned to full TMR security before their peak demand window.
Case 2: Proactive Upgrade of Obsolete Infrastructure A chemical processing plant used the VMIVME-7614 series for their compressor controls. Knowing these boards were reaching EOL (End of Life), they purchased one IS215UCVEH2AF as a “Last-time-buy” insurance policy. Six months later, a power surge fried the existing controller. Because they had the spare on hand, the “Mean Time to Repair” (MTTR) was only 2 hours instead of weeks of waiting for a repair service.
Frequently Asked Questions (FAQ)
Q: What is the difference between the IS215UCVEH2AF and the VMIVME-7614? A: The VMIVME-7614 is the “base” commercial-off-the-shelf board made by VMI (now part of GE/Abaco). The IS215UCVEH2AF is the GE “version” which includes specific GE firmware, coatings, and testing for the Mark VI Speedtronic environment. Always use the IS215 part number for turbine applications.
Q: Do I need to reload the Operating System? A: The OS (usually QNX) resides on the CompactFlash card. If you move your old card to the new board, it should boot normally. If the new board comes with a blank card, you must use the GE Toolbox to format and load the system files.
Q: Why is my “Fail” LED solid red? A: This typically indicates a Power-On Self-Test (POST) failure. It could be a seating issue (try re-seating the board) or a mismatch in the BIOS settings. Connecting a serial terminal to COM1 will tell you exactly where the boot process is hanging.
Q: Can I use this in an Innovation Series Drive? A: Yes, the UCVE series was used in both Mark VI Turbine Controls and some high-end Innovation Series Drives. The hardware is the same, but the firmware loaded via the Toolbox will differ.
Q: Is “New Surplus” reliable for a 20-year-old design? A: To be honest, it’s more reliable than a “refurbished” board. Refurbished boards have been subjected to years of heat and vibration. Our New Surplus units have been stored in anti-static, climate-controlled environments and are functionally identical to a factory-new part from the original production run.
Q: Does this include the PMC daughterboard? A: This specific part number refers to the main processor board. If your original setup had a daughterboard (like a DLAN or additional Ethernet card) attached to the PMC slots, you will need to move that daughterboard to the new IS215UCVEH2AF.
