Features:
- Four RJ45 ports place Ethernet automation devices on the router’s local 10/100 Mbit/s network.
- Two SMA antenna sockets use MIMO technology for the European cellular radio connection.
- Firewall, NAT and VPN functions control how local IP traffic crosses the mobile network.
The SCALANCE M876-4 separates its wired automation LAN from the GSM, UMTS or LTE wide-area connection.
Cellular traffic can be routed or encrypted while the local switch continues to connect as many as four Ethernet devices.
One digital input and one digital output provide local signaling independently of packet handling and management services.
The Siemens 6GK5876-4AA00-2BA2 SCALANCE M876-4 LTE Router may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Moving automation traffic over mobile radio
- Regional radio: The 2BA2 variant is optimized for the documented European GSM, UMTS and LTE frequency bands.
- MIMO path: Two 50-ohm SMA sockets connect the antenna pair used by the cellular interface.
- Packet transfer: IP traffic from the local Ethernet switch is forwarded through the selected mobile service.
- Approval boundary: National radio approvals must be checked for the country in which the router will operate.
Controlling traffic between LAN and LTE
- Stateful firewall: Connection state and packet-filter rules determine which traffic can cross the router.
- Address translation: NAT, one-to-one NAT and port forwing map local addresses to the mobile side.
- IPsec tunnels: The router establishes encrypted IPsec paths with supported authentication and AES key lengths.
- OpenVPN client: A separate OpenVPN client mode is available when that tunnel type is selected.
Organizing the local automation network
- Four-port switch: Four autocrossover RJ45 ports connect local devices at 10 or 100 Mbit/s.
- DHCP service: The router can act as a DHCP client and can serve addresses on its internal network.
- DNS handling: A DNS cache stores resolved names for clients on the local side.
- WAN separation: The cellular interface remains distinct from the four physical LAN ports.
Configuring the router and reading diagnostics
- Web interface: Web-based management provides the documented browser configuration path.
- Command line: CLI access offers a separate text-based method for supported settings.
- SNMP versions: SNMP v1, v2, v2c and v3 expose management information to a monitoring system.
- Event records: SysLog and the packet-filter log record operating and firewall events for review.
