Description
Product Overview
The EtherWAN EX78822-VVBT is a hardened managed PoE Ethernet switch built for industrial networks requiring powered copper connections and flexible fiber uplinks. It combines eight 10/100BASE-TX PoE ports, two 100BASE-SFP slots and two 100/1000BASE-SFP slots in a compact DIN-rail enclosure. With a maximum 240W PoE budget, redundant 52-57VDC power inputs and managed Layer 2 networking, the switch supports IP surveillance, transportation infrastructure, industrial automation and distributed security installations. Its fanless design and -40 to 75°C operating range support deployment in demanding industrial environments.
The EtherWAN EX78822-VVBT is a hardened managed industrial Ethernet PoE switch in the EX78000 Series, available through Coremicro, an authorized EtherWAN dealer based in Union City, California. The model includes eight 10/100BASE-TX PoE ports, two 100BASE-SFP slots and two 100/1000BASE-SFP uplink interfaces. EtherWAN specifies PoE output up to 60W per port with a maximum combined power budget of 240W, redundant 52-57VDC terminal-block input, Alpha-Ring network redundancy and DIN-rail mounting. The switch uses a fanless IP30 metal enclosure and supports operating temperatures from -40 to 75°C. EtherWAN lists a limited lifetime manufacturer warranty subject to its warranty policy. The EX78000 Series was discontinued on August 6, 2026, so remaining inventory, warranty eligibility and replacement options should be confirmed before purchase.
Eight Fast Ethernet PoE Ports
Eight 10/100BASE-TX Ethernet ports deliver network data and Power over Ethernet to compatible connected equipment through a single cable. The switch supports IEEE 802.3af, 802.3at and 802.3bt power delivery modes, with output capabilities up to 60W per port under supported configurations. This makes the platform suitable for industrial IP cameras, security equipment and other powered Ethernet devices. Each endpoint must be checked for its required PoE standard, power consumption and network bandwidth before installation.
Four SFP Fiber Uplink Interfaces
Four optical transceiver slots provide connectivity between local copper Ethernet devices and fiber network infrastructure. Two dedicated 100BASE-SFP slots support Fast Ethernet fiber links, while two dual-rate 100/1000BASE-SFP slots provide additional flexibility for Fast Ethernet or Gigabit fiber connections. This interface configuration supports distributed industrial networks, transportation infrastructure and security installations with remote network segments. Compatible SFP modules must be selected for the required fiber type, transmission distance and link speed.
240W PoE Budget with 60W Output
The EX78000 Series supports a maximum combined PoE power budget of 240W across its powered Ethernet ports. EtherWAN specifies individual port output levels of 15.4W, 30W and up to 60W, allowing compatible equipment with different power requirements to share the same switching platform. A PoE watchdog function helps monitor connected powered devices, while extended-distance PoE operation up to 250 meters is specified for supported configurations. Actual power availability depends on the DC power supply, connected devices and installation conditions.
Managed Ethernet Control and Security
Managed network features provide administrators with tools to configure traffic, monitor connected devices and maintain network access control. Supported interfaces include CLI, Telnet, web browser management and SNMP v1/v2c/v3, alongside EtherWAN eVue and eLite network management tools. Security functions include IEEE 802.1X authentication, RADIUS, TACACS+, SSH, SSL, MAC address filtering, access control lists and storm control. Port mirroring, RMON, DHCP services, LLDP and NTP support network diagnostics and administration.
Alpha-Ring Redundancy and VLAN Networking
EtherWAN Alpha-Ring redundancy is designed to maintain network availability when a link fails within a correctly configured ring topology. The manufacturer specifies recovery in less than 15 milliseconds for supported Alpha-Ring configurations. Additional Layer 2 functions include IEEE 802.1Q VLANs, GVRP, GMRP, IEEE 802.3ad LACP, IGMP snooping v1/v2/v3 and STP/RSTP/MSTP. These features support segmented traffic, controlled multicast distribution and redundant network paths across industrial Ethernet installations.
Hardened Fanless DIN-Rail Design
The compact metal enclosure combines fanless operation, IP30 protection and DIN-rail mounting for industrial control cabinets and infrastructure equipment rooms. Its published operating temperature range extends from -40 to 75°C, with environmental specifications covering vibration, shock and electrical interference. Redundant 52-57VDC terminal-block inputs provide power connection options for industrial installations. The chassis measures 71.4 × 140 × 170 mm and weighs 1.7 kg, allowing integration into cabinets where installation space and thermal conditions must be managed carefully.

What is the EtherWAN EX78822-VVBT used for?
The EtherWAN EX78822-VVBT is a hardened managed PoE Ethernet switch used to connect powered network devices and fiber infrastructure in industrial installations. Its eight Fast Ethernet PoE ports and four SFP slots support IP surveillance, transportation infrastructure and distributed security networks.
How much PoE power does the EX78822-VVBT provide?
The EX78822-VVBT supports a maximum total PoE budget of 240W, with individual port output capabilities up to 60W under supported configurations. Actual available power depends on the connected devices, installed power supply and deployment conditions.
Does the EX78822-VVBT support fiber network connections?
The EX78822-VVBT provides two 100BASE-SFP slots and two dual-rate 100/1000BASE-SFP interfaces for fiber networking. Compatible SFP transceivers must be selected according to the intended fiber type, connection distance and link speed.
Can the EX78822-VVBT operate in harsh industrial environments?
The EX78822-VVBT is rated for operation from -40 to 75°C and uses a fanless IP30 metal enclosure with DIN-rail mounting. EtherWAN also lists NEMA TS2 compliance and industrial environmental testing for the EX78000 Series.
How does EtherWAN Alpha-Ring network redundancy work?
EtherWAN Alpha-Ring provides network redundancy by supporting rapid recovery when a link fails in a correctly configured ring topology. The manufacturer specifies recovery below 15 milliseconds under supported conditions, while STP, RSTP and MSTP provide additional redundancy options.
