Overview

EW-PIS3912-8GE combines eight Gigabit PoE ports, two Gigabit RJ45 uplinks and two Gigabit SFP ports in an unmanaged industrial enclosure. Its 12–40VDC input and internal 48V PoE boost allow PoE deployment from low-voltage field power systems.

PoE booster

Convert low-voltage DC input into 48V PoE for connected endpoints.

12-port mix

Eight PoE copper ports, two RJ45 uplinks and two SFP ports cover industrial access.

Wire-speed switching

24Gbps capacity and full-wire-speed forwarding keep traffic moving.

Industrial protection

Redundant input, IP40 and 6kV lightning protection suit harsh cabinets.
