Initial power-up typically triggers a pre-installed bootloader. The next critical phase is flashing the operating system. Most users will download a system image from the vendor's portal and use a tool to write it to the onboard storage via USB. The first boot initiates the OS configuration wizard. Configuration options are vast and pivotal to performance. Key settings to address include:

• Network Configuration: Setting static IPs for Ethernet ports, configuring the 9907-164 5G module for cellular backup or primary WAN access—a common requirement for mobile or remote deployments in Hong Kong's outlying islands or port areas.
• Security Settings: Enabling secure boot, setting up firewall rules (iptables/nftables), and changing default credentials.
• Application Environment: Installing necessary SDKs, container runtimes like Docker, and specific drivers for connected sensors or actuators.
• Power Management: Configuring sleep states and wake-on-LAN features to optimize energy use.

Troubleshooting common issues is an essential skill. Problems often encountered include failure to boot (check power supply and boot media), network interface not detected (verify driver inclusion in kernel), or peripheral communication errors (confirm serial port configuration and baud rate). The system logs, accessible via UART console or SSH, are the first point of investigation. For persistent hardware communication issues, verifying the signal integrity and power levels managed by the ADR541-P50 regulator can be crucial.
