Motorola MVME172PA-652SE VME Embedded Controller

Description

3. Key Technical Specifications

4. Product Introduction & Supply Chain Strategy

The Motorola MVME172PA-652SE is a 6U VME embedded controller built around the MC68060 processor. It provides 32 MB SDRAM, on-board SCSI and Ethernet, dual IndustryPack slots, and full VMEbus master capability for real-time industrial control, data acquisition, and legacy automation systems that still rely on the MVME172 platform.

Securing this board as New Surplus protects Total Cost of Ownership on installed VME systems. Genuine new-surplus units avoid the reliability risks of refurbished boards (degraded batteries, aging capacitors, connector wear). Because the board is discontinued, holding 1–2 units of buffer stock eliminates long lead-time exposure and supports planned last-time-buy decisions across multiple machines or sites.

5. Installation & Configuration Guide

Stage 1: Pre-Installation (Prep & Safety)
Perform full lock-out/tag-out on the VME chassis power. Wear a grounded ESD wrist strap. Photograph the existing board’s front-panel connectors, any IndustryPack modules installed, jumper settings, and cable routing. Verify the replacement is New Surplus and free of bent pins or physical damage.

Stage 2: Removal
Power down the chassis completely. Remove any IndustryPack modules if they will be transferred. Extract the board carefully using the ejector handles, avoiding contact with backplane pins.

Stage 3: Installation (Clone & Seat)
Set any configuration switches or jumpers to match the original board. Install the same IndustryPack modules (if used). Align the board with the VME guides and seat it firmly into the backplane connectors. Secure the front-panel ejectors and reconnect front-panel cables.

Stage 4: Power-On & Testing
Restore chassis power. Observe front-panel LEDs and verify the board passes power-on self-test / debugger initialization. Confirm Ethernet/SCSI visibility and communication with the host system or other VME modules before returning the chassis to service.

6. Firmware/Software Versions & Upgrade Notes

The board includes on-board debugger and diagnostic firmware. Application software is typically loaded from Flash, network, or external media and is system-specific.

Document the existing firmware revision and any boot parameters before replacement. A different firmware level or incorrect memory configuration can prevent proper boot or IP module recognition. Do not upgrade firmware during a simple hardware swap unless the entire system is re-validated. Retain original IndustryPack configuration and any custom EPROM contents if present.

7. Frequently Asked Questions (FAQ)

Q: Is this truly New Surplus or refurbished?
A: Brand New Surplus only. Original manufacturing, unused, with zero operating hours. Not pulled or repaired.

Q: Why is the price higher than used boards but lower than any remaining OEM list?
A: Pricing reflects genuine New Surplus inventory of a discontinued VME controller. It avoids the secondary failure risk of refurbished boards while remaining substantially below historical list pricing.

Q: Is the MVME172PA-652SE still in production?
A: No. It is a discontinued legacy board. Strategic buffer stock of 1–2 units is the recommended approach for plants still operating MVME172-based systems.

Q: Can the board be hot-swapped in a live VME chassis?
A: No. Always power down the chassis completely. Live insertion risks backplane damage and system faults.

Q: Will the new board require software or configuration changes?
A: In most cases the original software and IP module configuration can be retained. Verify memory size settings and boot parameters match the previous board.

Q: What warranty is provided?
A: Standard 1-year warranty covering manufacturing defects. Visual inspection and basic power-on verification are performed prior to shipment.
