Introduction

The RKS-G4030-PL-L3 Series is purpose-built to deliver exceptional reliability and performance for mission-critical industrial and business applications, including power substation automation, railway operations, and intelligent transportation systems.

With its high-density 10GbE backbone (up to 6 fixed 10G SFP+ ports), modular LAN expansion (up to 16 additional Gigabit ports), and dual isolated redundant power supply options (12/24/48 VDC, 110/220 VAC/VDC), the RKS-G4030-PL-L3 Series ensures robust communication while reducing wiring and maintenance costs.

Even better, the dual-sided power installation design (front or rear) maximizes installation convenience for diverse cabinet layouts.

Additional Features and Benefits

Layer 3 switching functionality to move data and information across networks
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
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 or ABC-03 automatic backup configurator
Out-of-band management (OOBM) port to ensure the availability of network management when in-band services are inaccessible
