Teltonika RUT951-LTE Industrial Cellular Router w/ PoE & PSU

Access the router's web interface via its LAN IP. Navigate to the 'Mobile' section within RutOS. Here, you can set the primary and backup SIM cards, define failover triggers (like signal loss or data limit), and configure the network mode priority (4G > 3G > 2G). The system will automatically switch to the backup SIM when the primary connection meets your defined failure conditions, ensuring continuous uptime for critical applications.

In the RutOS web admin panel, go to 'Services' > 'VPN'. Choose your VPN protocol (e.g., OpenVPN or IPsec). For an OpenVPN client, upload your .ovpn configuration file or manually enter server details, certificates, and keys. Assign the tunnel to a specific WAN interface (like the LTE connection). Save and apply the configuration; the router will establish the secure tunnel, allowing all traffic from connected LAN devices to route through the VPN for encrypted remote access or site-to-site connectivity.

The digital input (DI) can monitor a dry contact or voltage (0-30V). Configure its function in 'System' > 'I/O' to trigger events like sending an SMS alert, logging to a server, or rebooting the router when the contact state changes. The digital output (DO) is a open-drain transistor that can switch an external load (up to 30V, 100mA). You can control it manually from the web interface, schedule it, or activate it based on network events (e.g., VPN tunnel down) for automating external alarms or relays.

Yes, using its passive PoE feature. Connect the router's DC power source (9-30V) to its power terminal. Then, use an Ethernet port configured for passive PoE output (typically the WAN port) to connect to your powered device (e.g., an IP camera). The router will inject DC power onto the Ethernet cable's spare pairs. Ensure your connected device is compatible with passive PoE at the same voltage. This eliminates the need for a separate power adapter at the remote endpoint, simplifying installation.
