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

• 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

• RMON for proactive and efficient network monitoring

• Bandwidth management prevents unpredictable network status
  with “Lock port” to restrict access to authorized MAC addresses
