5. Installation & Maintenance Guidelines
- Rack Installation: Use a standard 6U VME rack. Align the card with the slot and push it in until the rear buckle locks securely.
- Power Connection: Use a stable 12 V DC, 20 A power supply. Check the polarity before connecting to the VME backplane power port.
- Heat Dissipation: The module is equipped with a passive heatsink. Install it in a well-ventilated cabinet; additional fans can be added if necessary.
- Memory/Storage Replacement: Turn off the power before removing and replacing SODIMM and CF cards according to specifications. Hot-swappable PMC cards can be replaced during operation.
- Software Configuration: Enter BIOS/UEFI after startup to set the VMEbus boot order. Install the corresponding operating system (e.g., Windows Embedded, Linux) and drivers.
- Regular Inspection: Every 6 months, check power interfaces and heatsinks for dust accumulation, verify slot locking, and monitor key parameters (temperature, voltage).
