  • Layer 3 switching to divide large networks into different subnets and allow data and information to communicate across networks 
  • IEEE 1588 PTP (Precision Time Protocol) for precise time synchronization of networks
  • DHCP Option 82 for IP address assignment with different policies
  • Modbus/TCP protocols for device management and monitoring 
  • Turbo Ring, Turbo Chain, and RSTP/STP for network redundancy
  • IGMP Snooping and GMRP for filtering multicast traffic from industrial Ethernet protocols
  • IEEE 802.1Q VLAN and GVRP protocols to ease network planning
  • QoS (IEEE 802.1p/1Q) and TOS/DiffServ to increase determinism
  • 802.3ad and LACP for optimum bandwidth utilization
  • IEEE 802.1X, HTTPS, and SSH to enhance network security
  • SNMPv1/v2c/v3 for different levels of network management
  • RMON for efficient network monitoring and proactive capability
  • Bandwidth management ensures stable network performance
  • Lock port to restrict access to authorized MAC addresses
  • Port mirroring for online debugging
  • Automatic warning by exception through email and relay output


Process automation and transportation automation applications combine data, voice, and video, and consequently require high performance and high reliability. The ICS-G7848/G7850/G7852 series full Gigabit backbone switches’ modular design makes network planning easy, and allows greater flexibility by letting you install up to 48 Gigabit Ethernet ports plus 4 10 Gigabit Ethernet ports. The ICS-G7848/G7850/G7852 series also supports Layer 3 routing functionality to facilitate the deployment of applications across switches networks, making them ideal for large scale industrial networks. The ICS-G7848/G7850/G7852’s full Gigabit capability increases bandwidth to provide high performance and the ability to quickly transfer large amounts of video, voice, and data across a network. The switches support the Turbo Ring, Turbo Chain, and RSTP/STP redundancy protocols, and are fanless and come with an isolated redundant power supply to increase system reliability and the availability of your network backbone.
