Etherwan Systems EX78934E-0VB Hardened Managed L3 Poe Switch

Product Description

The ETHERWAN SYSTEMS, INC. EX78934E-0VB is a hardened managed Layer 3 Ethernet Power over Ethernet switch built for demanding network infrastructure deployments. Layer 3 switching enables IP routing between network segments directly at the switch level, reducing reliance on upstream routers. The managed architecture gives network engineers full control over VLANs, QoS policies, and traffic prioritization. PoE capability allows the switch to deliver power and data over standard Ethernet cabling to connected devices such as IP cameras, access points, and VoIP endpoints. The hardened construction is suited for environments where temperature extremes, vibration, or electrical noise are concerns.

This switch is intended for industrial, transportation, utility, and commercial building automation applications where network reliability is critical. Its Layer 3 feature set supports environments requiring inter-VLAN routing and advanced traffic management without a dedicated routing appliance. Installation and configuration are typically handled by licensed network engineers or systems integrators familiar with managed switch deployment and industrial Ethernet standards.

Key Features

• Layer 3 managed switching with inter-VLAN routing capability
• Power over Ethernet output for connected endpoint devices
• Hardened design suited for industrial and harsh-environment installations
• Full management interface for VLAN, QoS, and network policy configuration
• Ethernet connectivity supporting structured cabling infrastructure

Compatibility

Designed as an OEM-style managed Layer 3 PoE switch for integration into industrial Ethernet network infrastructure. No specific compatible device models or replacement part numbers were provided in the available product data.

Installation Notes

Installation should be performed by a qualified network engineer or licensed systems integrator. Power down connected devices and de-energize PoE-powered endpoints before servicing the switch or modifying cabling. Follow applicable local electrical codes and the facility network topology plan when configuring VLANs and routing tables. Do not exceed the rated PoE power budget across connected ports.
