The EtherWan EtherWAN-EX789xxH-0VB Hardened Managed 12-Port Gigabit PoE and 4-Port 1G SFP Ethernet Switch is a high-performance managed PoE switch designed for critical networks in harsh environments. It offers a compelling combination of flexibility, speed, and reliability, making it ideal for applications in urban infrastructure, transportation, security, and other sectors where consistent connectivity is essential.

The EX78900H provides users with a choice between 8 or 12 Gigabit Ethernet ports for connecting bandwidth-intensive devices. Additionally, it includes 2 or 4 SFP ports for connecting to fiber optic networks, enabling long-distance connections. Full duplex switching further enhances data transfer speeds by facilitating simultaneous transmission and reception of data.

The EX78900H is built to withstand extreme temperatures, operating reliably in a wide range from -40°C to 75°C (-40°F to 167°F). This makes it suitable for harsh environments where other switches might struggle. Its fanless operation ensures silent operation and eliminates the need for maintenance associated with cooling fans. The rugged construction resists high impact, thermal shock, and electrical noise, making it a perfect fit for industrial environments.

For efficient network traffic routing and segmentation, the EX78900H offers Layer 3 functionality with static routing, RIP v1/v2, and OSPF support. VRRP redundancy provides failover capabilities for increased network uptime.

The switch supports the advanced IEEE 802.3bt standard, delivering up to 90 watts of PoE power per port. This is ideal for powering high-wattage devices such as PTZ cameras and VoIP phones. With a total PoE power budget of 360 watts, the EX78900H can power multiple devices simultaneously. A PoE watchdog monitors and automatically reboots unresponsive PoE devices for reliable operation.

Extensive management and security features are also included. Granular port control provides comprehensive control over individual switch ports, including traffic management and security settings. Secure communication is ensured with support for Secure Shell (SSH) File Transfer Protocol (SFTP). Additionally, 802.1X network access control enhances network security by authenticating devices before granting access. For centralized management, the switch can be configured and monitored remotely using EtherWAN's eVue™ and eLite™ management platforms.

EtherWAN offers complimentary technical support to assist with any questions or troubleshooting needs. Free firmware upgrades ensure the switch stays up-to-date with the latest features and security patches. Finally, a limited lifetime warranty provides peace of mind for users.

The EtherWAN EX78900H is a powerful and versatile managed PoE switch that empowers users to build robust and reliable networks in demanding environments. Its combination of high-bandwidth connectivity, hardened design, advanced PoE features, and comprehensive management tools make it an ideal solution for various applications.
