Setup
- Unpacking: Carefully remove the Protectli Vault and all accessories from the packaging. Verify that all components listed in the packing slip are present.
- Physical Placement: Place the device on a stable, flat surface with adequate ventilation around the chassis. Although fanless, proper airflow aids in heat dissipation.
- Connect Peripherals:
- Connect a monitor to the HDMI port (Figure 3).
- Connect a keyboard and mouse to the USB 3.0 ports (Figure 3).
- (Optional) For console access, connect a serial cable to the RJ-45 COM port (Figure 3) and connect it to another computer.
- Network Connections:
- Connect your internet source (e.g., modem) to the WAN port (Figure 2).
- Connect your internal network (e.g., switch, computer) to the LAN port (Figure 2).
- Utilize the OPT1-OPT4 ports (Figure 2) for additional network segments as required by your chosen operating system.
- Power Connection: Connect the provided 12V DC power adapter to the DC 12V input port on the rear panel (Figure 2), then plug the adapter into a power outlet.
- Initial Boot and OS Installation:
- Press the power button on the front panel (Figure 3).
- The Protectli Vault does not come with a pre-installed operating system. You will need to install your preferred open-source firewall or routing software (e.g., pfSense, OPNsense, Untangle) from a USB drive or other bootable media.
- Follow the installation instructions provided by your chosen operating system.
Operating Instructions
Once your chosen operating system is successfully installed and configured, the Protectli Vault will function according to the software's capabilities.
- Power On/Off: Use the power button on the front panel to turn the device on or off. A short press typically initiates a graceful shutdown (if supported by the OS), while a long press performs a hard power off.
- Fanless Operation: The Protectli Vault is designed for silent operation without active cooling fans. This reduces noise and dust accumulation, making it ideal for various environments.
- Software Configuration: All network routing, firewall rules, and other functionalities are managed through the installed operating system's interface. Refer to the documentation of your specific OS for detailed configuration steps.
- Performance: The Intel Core i7 processor and multiple Gigabit Ethernet ports provide ample performance for high-throughput network security applications.
Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your Protectli Vault.
- Cleaning: Periodically clean the exterior of the device with a soft, dry cloth. Avoid using liquid cleaners directly on the device. Ensure the heatsink fins (top of the device) are free from dust buildup to maintain efficient passive cooling.
- Software Updates: Regularly update the operating system and any installed software to ensure you have the latest security patches and performance improvements. Refer to your OS documentation for update procedures.
- Environmental Conditions: Operate the device within recommended temperature and humidity ranges. Avoid placing it in direct sunlight or near heat sources.
- Cable Management: Ensure all cables are securely connected and not under strain. Proper cable management can prevent accidental disconnections and improve airflow.
Troubleshooting
This section provides solutions to common issues you might encounter.
