More Information

Overview Manuals Combo Ports Firewall & VPN Routing Mounting & Climate

Features:

  • Two combo connections support copper or optical Gigabit Ethernet network paths.
  • Stateful firewall and IPsec/OpenVPN functions secure traffic between separated network cells.
  • Redundant 24 V DC inputs and a signal contact support monitored cabinet integration.
Siemens 6GK5642-2GS00-2AC2 separates the protected and external Ethernet sides through two configurable combo connections.

Routing can use static entries, VRRP, OSPFv2 or OSPFv3, while VPN authentication accepts pre-shared keys or X.509 certificates.

Web Based Management, CLI and SNMP expose configuration and diagnostic functions for the SCALANCE SC642-2C platform.

The Siemens 6GK5642-2GS00-2AC2 SCALANCE SC642-2C Security Appliance may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Copper and Optical Connection Roles

  • Interface assignment: One combo position faces the external network while the other serves the protected network.
  • Media selection: Each position can use either its electrical Ethernet interface or a suitable optical SFP path.
  • Traffic path: Data crossing the two interface roles passes through the configured security and routing rules.
  • Port behavior: Copper and optical media at one combo position are alternative paths rather than simultaneous extra ports.

Traffic Inspection and Encrypted Tunnels

  • Firewall processing: Stateful packet inspection evaluates traffic against rules assigned between the external and protected sides.
  • IPsec tunnels: IPsec secures authenticated IP communication between defined remote endpoints.
  • OpenVPN service: OpenVPN provides another encrypted tunnel path for configured remote connections.
  • Authentication: Pre-shared keys or X.509 certificates establish the permitted VPN peer identity.

Route Exchange and Gateway Redundancy

  • Static paths: Static entries direct packets through fixed IP network routes.
  • Router redundancy: VRRP coordinates the active gateway role between redundant routers.
  • IPv4 exchange: OSPFv2 distributes IPv4 routing information between participating devices.
  • IPv6 exchange: OSPFv3 distributes IPv6 routing information through the configured routing domain.

Cabinet Mounting and Operating Limits

  • Rail mounting: The housing can attach to a 35 mm DIN rail, S7-300 rail, or S7-1500 rail.
  • Wall mounting: The enclosure also supports fixed wall installation when rail hardware is not used.
  • Enclosure protection: IP20 protection requires installation inside a suitable protected enclosure.
  • Climate limit: Operation from -40 to +70 °C permits up to 95% relative humidity without condensation.
Description
The Siemens 6GK5642-2GS00-2AC2 is a SCALANCE SC642-2C industrial security appliance in the SCALANCE S family. It places firewall, VPN and routing functions between Ethernet cells so traffic can be filtered and protected at the network boundary.

Two combo connections let 6GK5642-2GS00-2AC2 use either copper Ethernet or suitable optical SFP paths at each network side. This structure allows the protected and external networks to remain physically distinct while the appliance applies the configured communication rules between them.

Security policies in 6GK5642-2GS00-2AC2 combine stateful packet inspection with IPsec or OpenVPN tunnels. Certificate or pre-shared-key authentication establishes the encrypted path, and the routing layer can exchange traffic through static routes, VRRP, OSPFv2 or OSPFv3.

Redundant 24 V DC inputs power 6GK5642-2GS00-2AC2, while the two-pole signal contact reports device status to an external circuit. Web Based Management, CLI and SNMP provide separate paths for configuration, diagnostics and event review without merging those functions into the protected data traffic.

For cabinet integration, 6GK5642-2GS00-2AC2 can be secured on a 35 mm DIN rail, S7-300 rail, S7-1500 rail or wall surface. Its IP20 enclosure and specified -40 to +70 °C operating range define the environmental limits for the installed device.
