EDS-518A Series

16+2G-port Gigabit managed Ethernet switches

Features and Benefits

2 Gigabit plus 16 Fast Ethernet ports for copper and fiber
Turbo Ring and Turbo Chain (recovery time < 20 ms @ 250 switches), Gigabit Ethernet recovery time < 50 ms RSTP/STP, and MSTP for network redundancy
TACACS+, SNMPv3, IEEE 802.1X, HTTPS, and SSH to enhance network security
Easy network management by web browser, CLI, Telnet/serial console, Windows utility, and ABC-01

Certifications

Introduction

The EDS-518A standalone 18-port managed Ethernet switches provide 2 combo Gigabit ports with built-in RJ45 or SFP slots for Gigabit fiber-optic communication. The Ethernet redundancy technologies Turbo Ring and Turbo Chain (recovery time < 20 ms) increase the reliability and speed of your network backbone. The EDS-518A switches also support advanced management and security features.

Additional Features and Benefits

Command line interface (CLI) for quickly configuring major managed functions
DHCP Option 82 for IP address assignment with different policies
Supports EtherNet/IP and Modbus TCP protocols for device management and monitoring
Compatible with PROFINET protocol for transparent data transmission
Supports the ABC-01-USB (Automatic Backup Configurator) for system configuration backup
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 and TOS/DiffServ) to increase determinism
Port Trunking for optimum bandwidth utilization
SNMPv1/v2c/v3 for different levels of network management
RMON for proactive and efficient network monitoring
Bandwidth management to prevent unpredictable network status
Automatic warning by exception through email and relay output
