4. Product Introduction
The ADLINK CPCI-3840AH (cPCI-3840 series) is a dual-slot 3U CompactPCI processor module built around the low-power Intel Pentium M or Celeron M processor. It provides dual Gigabit Ethernet, flexible storage interfaces, and hot-swap capability for industrial embedded computing platforms.
Engineers deploy this board in CompactPCI chassis used for machine control, transportation, test & measurement, and SCADA-related systems that require a proven, long-lifecycle x86 platform. The module supports front-panel and rear-transition I/O, making it suitable for both laboratory and field-installed racks. Current availability is primarily New Surplus or tested residual stock.

5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Board does not power up / no LEDs | Backplane power or seating issue | ✅ High | Measure +5 V / +3.3 V on backplane; reseat board firmly | Verify chassis power supply and guide rails |
| No video output | Display cable or BIOS setting | ✅ High | Test VGA port; check if RTM is required for DVI | Confirm front-panel VGA connection first |
| Ethernet link fails | Cable, driver, or port configuration | ✅ High | Check link LEDs; test both front and rear ports | Verify network settings and cable integrity |
| System fails to boot from storage | IDE/CF/SATA configuration or media fault | ✅ Medium | Check BIOS boot order and CompactFlash master/slave jumper | Test with known-good CF card or HDD |
| Hot-swap fails or system hangs | Improper extraction sequence or firmware | ✅ High | Follow PICMG 2.1 hot-swap procedure exactly | Power down or use controlled extraction if unsure |
If the issue persists, record LED status, BIOS version, and chassis configuration details before contacting support.
6. Frequently Asked Questions (FAQ)
Q: What does the “AH” suffix indicate on CPCI-3840AH?
A: It typically denotes a specific configuration or regional/listing variant of the cPCI-3840 series. Confirm the full part number (CPU speed, memory size, storage option) against your existing board or system documentation.
Q: Is this board still supported by ADLINK?
A: The cPCI-3840 is a legacy product based on the Intel Pentium M platform. Official new production has ended. Available units are New Surplus or carefully tested stock. Driver and BIOS support is limited to the original release packages.
Q: Does it support hot-swap?
A: Yes. It complies with PICMG 2.1 CompactPCI Hot Swap Specification. Always follow the correct extraction/insertion sequence and use the hot-swap LED indicators.
Q: What rear transition module is required?
A: The matching RTM is typically the cPCI-R3840 (or equivalent). It provides additional rear I/O including DVI, Ethernet, USB, and serial ports.
Q: Can I upgrade the memory or CPU?
A: Memory can usually be upgraded within the supported SODIMM limits (up to 2 GB). The CPU is soldered or socketed depending on exact revision; field CPU upgrades are generally not practical or supported.
Q: Why is this priced lower than current CompactPCI blades?
A: It is a discontinued product sold as New Surplus or residual inventory. Pricing reflects remaining stock rather than current manufacturing cost. All units undergo visual and basic functional verification before shipment. Standard warranty is typically 12 months.
Q: What operating systems were commonly used?
A: Windows XP Embedded, older Linux distributions, and real-time operating systems validated for the Intel 855GME platform. Modern OS support is limited or unavailable.
