The FL SWITCH EP 7400 series of advanced modular managed network switches provides an adaptable platform to meet the electric power industry’s increasing requirements for scalable network performance, uptime, and security. The modular 19" rack-mount switch is hardened for areas heavily affected by EMI, such as switchgear, transformer stations, and local substations. The switch works reliably under extreme environmental conditions (-40°C to +75°C / 85°C) and complies with the IEC 61850-3 Ed 2, and IEEE 1613 specifications. The expandable “all gigabit capable” architecture combines cost-effective answers for near-term needs with upgrade paths for port quantity/bandwidth and functions. A powerful Layer 2 and Layer 3 feature set with hardware-based IEEE 1588 V2 PTP synchronization based on the IEC 61850-9-3 Utility Power Profile provides extensive options to meet changing performance and security needs. The 28-port switch has 4 module slots. 3 slots accept 10/100/1000Mbps port modules (up to 8 ports) for device connections, and a 4th slot supports a 4-port SFP module with 1 or 10 Gigabit uplinks for device connections. SFP module options provide further single-point TX/fiber connection customization, while allowing for electrically isolated and secure communication lines between the control house and equipment throughout the station. Power is provided by redundant modular power supplies. The modules are designed for power source flexibility (AC/DC) and allow hot-swappable replacement for uninterrupted 24/7 operation.
