Emerson MVME7100 6U VME Single‑Board Computer

Description

Core technical features

Processor: Dual‑core MPC864xD, clock speed options 1.06 GHz / 1.3 GHz. Memory: Up to 2 GB DDR2 ECC RAM; 128 MB NOR flash, plus optional NAND flash (2‑8 GB). Network: Four independent gigabit Ethernet interfaces. Supports PMC‑X / XMC expansion slots for adding custom function boards. VME bus conforms to 2eSST high‑speed transmission protocol. Multi‑channel serial debug ports, USB2.0 interfaces are available. Supported operating systems: VxWorks, Linux, LynxOS real‑time systems. Operating ambient: Commercial version 0℃~+60℃; rugged extended‑temperature variant ‑40℃~+71℃; humidity 5‑95% non‑condensing; cabinet‑inside installationmvme.net. Compatibility notes: It is a standard 6U VME Eurocard. Matched transition RTM module (MVME7216E) is required for rear‑side I/O wiring. Pay attention to firmware and BSP board‑support‑package version consistency during replacement; mismatched files will cause boot failurestatic6.ar….

Physical construction

Standard 6U VME single‑slot board structure. Front panel has extraction ejector latches and multi‑status LED indicators. Rear P1/P2 gold‑plated VME connectors connect to chassis backplane for power supply and bus signal transmission. All external I/O signals are routed via rear transition module. The part number MVME7100 is marked on board label. PCB is conformal‑coated to resist dust and slight corrosive gas inside industrial cabinetsmvme.net.

Field practical information

This board works as main computing unit inside VME chassis. It undertakes real‑time data calculation, field‑bus data processing and system logic control tasks, widely used in simulation test platforms, energy‑industry special control equipment and legacy industrial computer transformation projects. Hardware failure will lead to the whole VME host system stop working. When performing replacement, power off chassis completely and apply ESD anti‑static measures. After inserting the board, check all rear‑side transition‑cable connections, install corresponding system firmware and board‑support‑package, complete system startup test and network communication verification before formal commissioning.

Installation & maintenance reminders

Power must be cut off before board swapping. Do not damage golden‑finger contacts of VME connector during handling. Separate network and serial signal cables from high‑power cables to reduce electromagnetic interference. Preserve original firmware image and system configuration files for reference. On‑site board‑level component repair is forbidden; replace complete SBC assembly when permanent hardware damage occurs.

Common on‑site fault phenomena

1. Board cannot boot: Check VME backplane contact status, verify firmware / BSP version matching.
2. Ethernet ports cannot work normally: Inspect RTM transition‑module cable connection and network hardware configuration.
3. Intermittent system crash or reset: Check cabinet cooling airflow, confirm board power‑supply derating margin.
4. Expansion PMC‑X module not recognized: Confirm slot hardware contact and driver compatibility.
