ipELB 4-Port Ethernet Line Breaker with integrated I/O module Secure Remote Maintenance ipELB is a cybersecurity system for industrial networks that can physically disconnect Ethernet connections. Each of its relay-controlled ports can be controlled manually via a toggle switch on the device (ON/OFF) as well as remotely (REMOTE). Software-wise, these can be controlled through a secure web interface, standardized communication protocols, or digital inputs. • • • • • • • Support for 10M / 100M / 1G and 10G Ethernet Transparent data transmission Controlled bidirectional data exchange between systems Network segmentation Monitoring and switching of digitals signals Daisy chain of multiple SEC3ER Conduct-through Power over Ethernet (PoE) THE MAIN FUNCTION The control unit for the separable Ethernet connections features three functional areas: • The status indicators • The mechanical control switches • Ethernet relay ports arranged in pairs A 3-way switch is provided for each Ethernet interface pair E1-E4 to manually control their connection state. Bistable relays are used as "ON/OFF switches" for each of the eight individual lines of an Ethernet connection. These retain their current state even after a power failure or an interruption in communication. A one-to-one pin allocation is applied to connect or disconnect the partner interfaces. THE HARDWARE The industrial 19" controller SEC3ER is used as a hardware platform. The hardware is entirely passively cooled and does not contain any moving parts. This maintenance-free solution offers a high degree of usability, reliability, and best cost-benefit ratio. More detailed technical data about SEC3ER with ipELB can be found at www.ipcomm.de With an increasing degree of networking between machines and industrial facilities, the need for remote maintenance access to optimize costs is likewise growing. At the same time, this raises the risk of cyber attacks, especially if systems with deprecated security mechanisms or legacy systems are deployed. With ipELB, network connectivity can be provided and monitored for secure remote maintenance. The maintenance connection can be physically disconnected, if currently not required. Thus potential attackers have no opportunity to exploit the idle port to implant malicious code. For seamless switching between redundant Internet providers (ISP), ipELB is ideally suited. The diagram shows the schematic structure of a corporate network. System operators can control and automate which ISP is set active. The corporate IT can also decide which connection is utilized by using the mechanical 3-way switches. The manual switching is prioritized over automa

CONTROL OPTIONS FOR THE ETHERNET RELAYS Redundancy Coupling for Standalone Systems • Mechanical 3-way switches The Ethernet relays of the interfaces E1-E4 can each be opened or closed manually via a 3-way switch. • Web configuration interface The status of all interfaces can be comfortably monitored and controlled in the diagnostics area of the configuration interface. Each Ethernet relay can be switched remotely using a web browser ̶ without requiring the use of telecontrol protocols. To ensure operation and reliability of critical systems, companies deploy redundant systems. Yet many devices...
