Product Description

The OTS ET4222PpH-S-DR is a rugged, industrial-grade Lite-Managed Gigabit Ethernet switch engineered for reliable networking in harsh environments. Featuring 4 Gigabit 10/100/1000Base-TX PoE+ ports and 2 Gigabit SFP fiber uplink ports, this switch provides a dependable solution for connecting IP cameras, wireless access points, industrial controllers, surveillance systems, and other network devices across manufacturing plants, transportation systems, utility networks, and outdoor installations. It combines high-speed data transmission, Power over Ethernet (PoE+), and advanced management capabilities in a compact, fanless design.

The four RJ45 ports support IEEE 802.3af/at PoE+, delivering up to 30W per port to power compatible devices without requiring separate power supplies. A built-in PoE extension mode allows both power and data transmission to reach up to 250 meters at 10 Mbps, making it ideal for long-distance IP camera deployments and remote network devices. The integrated PoE monitoring interface enables administrators to view power consumption, current, and temperature, simplifying maintenance and improving operational efficiency.

Designed for mission-critical applications, the ET4222PpH-S-DR includes dual redundant DC power inputs, automatically switching to the backup power source if the primary supply fails. This redundancy minimizes downtime and ensures continuous network operation. The switch also features an integrated fault alarm relay, which instantly reports power or network failures to connected monitoring systems for rapid troubleshooting
