Operating Precautions
- Firmware Sync: Ensure that the CPU firmware version matches the version of the VeriFire Tools used for system programming.
- Ground Faults: Verify that the system is free of ground faults before connecting the CPU to prevent board-level component damage.
- Ethernet Security: When using the onboard Ethernet port for networking, ensure the connection is behind a secure firewall or on a dedicated VLAN.
- Static Handling: Always utilize a grounded antistatic wrist strap when touching the board to prevent latent ESD damage to the microprocessor.
