Juniper Networks introduced its LN2600 ruggedized router for deployment in harsh environments where dust, heavy vibration, moisture and extreme temperatures are often the norm. It could be used for connecting remote telemetry units, surveillance cameras, programmable logic controllers and other intelligent devices.
The router combines switching, routing and security into a single platform, and contains no vents or other openings to keep it dust-free and splash-resistant.
