Description
NEXCOM PEAK715VL-HT | Socket 478 PICMG 1.0 SBC Board Specs
Architect’s Product Breakdown
The NEXCOM PEAK715VL-HT serves as a full-size PICMG 1.0 single board computer designed for legacy industrial automation, semiconductor fabrication equipment, and computer-telephony integration (CTI) racks. Built on the Socket 478 architecture supporting Intel Pentium 4, Celeron, and Pentium 4-M processors (with Hyper-Threading technology support up to 3.06 GHz+), this hardware model pairs the Intel 845GV graphics memory controller hub (GMCH) with the ICH4 I/O controller hub. By utilizing an integrated ITE 8888F PCI-to-ISA bridge chip, the SBC provides exceptional high-drive (64 mA) signal buffering across backplanes supporting up to 20 ISA expansion slots.
Deploying or servicing this model in active industrial control chassis requires configuring onboard jumper headers for CPU voltage/type (Pentium 4 vs. Pentium 4-M) and system power delivery modes (AT vs. ATX). Featuring two 184-pin DIMM sockets for up to 2 GB of non-ECC DDR 266/333 SDRAM, the board handles multi-axis motion control and legacy frame-grabber boards without suffering system bus bandwidth constraints. When executing maintenance replacements, automation engineers must verify that the single Intel 82551QM Fast Ethernet RJ-45 connection matches the networking requirement (distinguishing it from the dual-LAN PEAK 715VL2-HT variant).

Field Engineer’s Pitfall Guide (Unique Value)
- Selecting Double-Sided x16 DDR RAM Modules: The Intel 845GV memory controller on the PEAK715VL-HT does not support double-sided x16 DDR DIMM modules. Installing incompatible double-sided x16 memory sticks will cause the SBC to fail POST, resulting in continuous system beep codes or a black screen.
- Incorrect CPU Jumper Configurations (JP3): Installing a mobile Intel Pentium 4-M processor while jumper JP3 remains set to standard desktop Pentium 4 / Celeron mode will apply incorrect Vcore voltage levels, risking permanent destruction of the processor socket or VRM circuits.
- Inadequate +3.3V Power Derating from Backplane: While +5 V+5 V+5 V and +12 V+12 V+12 V rails feed directly from the PICMG backplane, +3.3 V+3.3 V+3.3 V is converted internally on this card from the +5 V+5 V+5 V line. Ensure the backplane power supply +5 V+5 V+5 V rail provides at least 12 A to avoid sudden system resets under heavy CPU loads.
QA & Testing SOP (Transparency)
- Visual & Origin Verification: Board assemblies undergo microscopic examination to confirm clean gold-plated PICMG edge fingers, unbent Socket 478 pins, solid surface-mount capacitors, and authentic OEM labeling.
- Live Test Bench Environment: SBCs are installed into a standard PICMG 1.0 passive backplane with a Socket 478 CPU and 2 GB DDR RAM to verify BIOS POST routines, onboard hardware monitoring, and thermal sensor telemetry.
- I/O & Expansion Bus Diagnostics: Technicians run memory stress sweeps (MemTest86), test 10/100 Ethernet throughput via the Intel 82551QM LAN controller, verify IDE/CompactFlash storage channels, and validate active communication across both ISA and PCI backplane expansion slots.
- Anti-Static Packaging: Post-testing units are fitted with protective socket covers, sealed inside anti-static ESD shielding bags, and securely cushioned with high-density foam packaging for transport.
Technical FAQ
Can I hot-swap the PEAK715VL-HT single board computer inside an active chassis? No. Standard PICMG 1.0 passive backplanes do not support live hot-swapping. Always power off the main system power supply before inserting or removing the SBC.
What is the difference between the PEAK 715VL-HT and the PEAK 715VL2-HT? The PEAK715VL-HT model features one Intel 82551QM 10/100 Fast Ethernet port, whereas the PEAK 715VL2-HT features dual 10/100 Ethernet ports.
Does this board support legacy ISA expansion cards? Yes. Equipped with an onboard ITE 8888F PCI-to-ISA bridge delivering 64 mA high-drive capability, this model can drive up to 20 ISA slots on a passive backplane.
What is the standard warranty status for surplus inventory units? Verified surplus or factory-sealed industrial SBC modules typically carry a 12-month operational warranty covering material and manufacturing defects under standard operating conditions.
