Introduction
28G-port (with 802.3bt PoE option) full Gigabit modular managed Ethernet switches
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 BenefitsLayer 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 RMON for proactive and efficient network monitoring Bandwidth management prevents unpredictable network status with “Lock port” to restrict access to authorized MAC addresses Port mirroring for online debugging Automatic warning by exception through email and relay output Automatic recovery of connected device’s IP addresses Configurable by web browser, Telnet/serial console, CLI, Windows utility, and ABC-02-USB automatic backup configurator
