The OttoE PoE 08H GE is a hardened industrial-grade unmanaged PoE switch built to operate reliably in extreme environments. Designed with IEEE 802.3bt (up to 90W per port) support and 6kV surge protection, this switch powers demanding PoE devices such as PTZ cameras, wireless access points, and edge AI equipment. Housed in a rugged metal casing, the OttoE PoE 08H GE features a wide operating temperature range of -40°C to 75°C, making it ideal for outdoor cabinets, roadside enclosures, and industrial field sites.

Engineered for plug-and-play deployment, OttoE PoE 08H GE includes per-port PoE watchdog via DIP switch to auto-recover frozen PDs, ensuring system uptime in unmanned locations. Built-in QoS, auto-negotiation, and auto MDI/MDIX provide seamless integration into industrial networks. This switch is a reliable solution for smart traffic systems, substation automation, smart grid infrastructure, renewable energy, and harsh industrial automation applications that demand high power, durability, and ease of use.

IEC 62443-4-2 Compliance – Built and reviewed according to IEC 62443-4-1 secure development practices.
