2.1 Description
FL SWITCH EP74… advanced modular managed network switches provide an adaptable
platform to meet the electric power industries increasing requirements for scalable network
performance, uptime and security.
The modular 19-in. 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 -40°C to +75°C/85°C environmental conditions 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 quan-
tity/bandwidth and functions. A powerful Layer 2 and Layer 3 feature set with hardware-
based IEEE 1588 V2 PTP synchronization, based on the IEC61850-9-3 Utility Power Profile,
provides extensive options to meet changing performance and security needs.
The 28-port switch has four module slots. Three slots accept 10/100/1000 Mbps port mod-
ules (up to eight ports) for device connections, and a fourth slot supports a four-port SFP
module with 1 or 10 Gigabit up-link or device connections. SFP module options provide fur-
ther 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 for hot-swappable replacement for uninterrupted
24/7 operation.
Power supply modules must be purchased separately.
