Features:
- Six network positions combine four fixed RJ45 ports with two RJ45/SFP combo ports.
- Stateful firewall, IPsec and OpenVPN functions protect traffic between industrial network segments.
- Dual DC supply inputs and an external signaling contact separate power redundancy from status reporting.
The six network positions of 6GK5646-2GS00-2AC2 do not operate as six identical sockets. Four are fixed copper interfaces, while each combo position uses either its RJ45 side or its installed SFP path.
Routing and address-translation functions let 6GK5646-2GS00-2AC2 pass selected traffic between IP networks while the firewall applies rules to the permitted connections.
Management traffic can reach 6GK5646-2GS00-2AC2 through HTTPS, CLI or SNMP, and its event logs distinguish security activity from port-level diagnostic information.
The Siemens 6GK5646-2GS00-2AC2 SCALANCE SC646-2C Industrial Security Appliance may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How the six network positions are assigned
- Fixed copper: Four RJ45 ports on 6GK5646-2GS00-2AC2 carry 10/100/1000 Mbit/s Ethernet.
- Combo selection: Each of the two combo positions uses either its RJ45 interface or its installed SFP interface.
- Optical choice: The SFP side accepts a 100 Mbit/s or 1000 Mbit/s optical transceiver path.
- Port total: Selecting an SFP path does not create an additional port beyond the six available network connections.
Traffic control and protected remote links
- Firewall processing: Stateful inspection on 6GK5646-2GS00-2AC2 evaluates traffic as part of an established connection.
- Encrypted tunnels: IPsec and OpenVPN provide separate supported methods for VPN connections.
- Address handling: NAT/NAPT translates addresses when traffic crosses configured network boundaries.
- Authentication: VPN peers can use preshared keys or X.509v3 certificates.
Services used to configure and observe the appliance
- Administration: HTTPS, CLI and SNMP provide management paths for 6GK5646-2GS00-2AC2.
- Event records: SysLog, packet-filter logs, audit logs and system logs separate different event sources.
- Routing: Static IPv4 and IPv6 routing moves approved traffic between configured subnets.
- Time services: NTP and SNTP functions align timestamps used by logs and diagnostics.
Mechanical and environmental boundaries
- Mounting options: 6GK5646-2GS00-2AC2 supports 35 mm DIN rail, S7-300 rail, S7-1500 rail and wall mounting.
- Enclosure rating: The IP20 design requires protection appropriate to the cabinet environment.
- Operating range: The specified ambient range applies from -40 °C to +70 °C.
- Humidity limit: Operation permits up to 95% relative humidity at 25 °C without condensation.
