ON-5708G-2F
The Optech Network Solutions ON-5708G-2F is an 8-port industrial Gigabit Ethernet switch with 6 × 10/100/1000Base-T(X) RJ45 ports and 2 × 100/1000Base-SFP combo ports. It is designed for industrial applications requiring high-bandwidth Ethernet connectivity with optional fiber expansion. The switch supports redundant 12/24/48 VDC power inputs, jumbo frames, broadcast storm protection, energy-efficient Ethernet, port-break alarms, and relay-based fault notification.
Key Features
8-Port Gigabit Connectivity 6 × 10/100/1000Base-T(X) RJ45 ports + 2 × 100/1000Base-SFP combo ports.
Flexible Fiber Expansion Two combo ports support 100/1000 Mbps SFP connectivity for fiber networking.
Redundant Industrial Power Dual 12/24/48 VDC power inputs with reverse-polarity protection.
Industrial Protection & Alarming Broadcast storm protection, port-break alarm, and relay output for power-failure/port-break warnings.
Heavy-Duty Industrial Construction IP30 metal enclosure, DIN-rail mounting, and wide-temperature versions supporting -40°C to 75°C.
