Introduction

The RKS-G4028 Series is designed to meet the rigorous demands of mission-critical applications for industry and business, such as power substation automation systems (IEC 61850-3, IEEE 1613), railway applications (EN 50121-4), and factory automation systems. The RKS-G4028 Series’ Gigabit and Fast Ethernet backbone, redundant ring, and 24 VDC, 48 VDC, or 110/220 VDC/VAC dual isolated redundant power supplies increase the reliability of your communications and save on wiring costs.

The modular design of the RKS-G4028 Series also makes network planning easy, and allows greater flexibility by letting you install up to 28 Gigabit ports with various connector types.

Additional Features and Benefits

  • Layer 3 switching functionality to move data and information across networks (L3 models only)

  • IEEE 1588v2 PTP (Precision Time Protocol) for network time synchronization

  • Command line interface (CLI) for quickly configuring major managed functions

  • DHCP Option 82 for IP address assignment with different policies

  • IGMP snooping and GMRP for filtering multicast traffic

  • Port-based VLAN, IEEE 802.1Q VLAN, and GVRP to ease network planning

  • QoS (IEEE 802.1p/1Q and TOS/DiffServ) to increase determinism

  • IEEE 802.3ad, LACP for optimum bandwidth utilization

  • Line-swap fast recovery

  • TACACS+, IEEE 802.1X, SNMPv3, HTTPS, and SSH to enhance network security

  • SNMPv1/v2c/v3 for different levels of network management
