iSEG RF-3180 Secure Gateway

General Description

3180 productThe iSEG RF-3180 Secure Gateway is a ruggedized, compact, secure switch/router with a base configuration of 2×100/1000 SFPs and 8×10/100 BaseT PoE ports and a variety of additional optional interfaces including 8×10/100 Base-T Ports, 8x100FX SFP Ports, 4xRS-232 Ports and a cellular modem.

Furthermore it supports a wide range of power inputs – 24/48/110/220 VDC, and 110/220 VAC.

As such it is ideally suited to operate in small, harsh environments cabinets found in remote utility sites according to the IEEE1613 and EN50121-4 standards.

Addressing the increasing risks of cyber attacks, the iSEG RF-3180 supports IPSec VPN tunnels and includes a firewall with service-aware inspection of SCADA protocols.

The iSEG RF-3180 advanced feature-set integrated in a compact platform makes it an ideal platform for deploying a Secure gateway for remote utility sites with critical utility infrastructures applications such as smart-grid and intelligent transportation.
