Description
Product Overview
The EtherWAN EX78924G-0BT is a hardened Layer 2/Layer 3 managed industrial PoE++ switch combining eight 10/100/1000BASE-T powered RJ45 ports with four tri-speed 100/1000/2500BASE SFP fiber uplinks. IEEE 802.3bt Type 4 supports up to 90W on an individual PoE port, subject to a shared 480W budget at temperatures through 70°C or 400W through 75°C. Static routing, OSPF, VLANs and ERPS support managed network designs for IP surveillance, transport infrastructure and industrial automation. Its fanless IP30 metal enclosure mounts on a DIN rail and operates from -40°C to +75°C.
The EtherWAN EX78924G-0BT is a 12-interface hardened L2/L3 managed Ethernet switch listed by Coremicro, an authorized EtherWAN dealer in Union City, California. EtherWAN specifies eight Gigabit IEEE 802.3af/at/bt PoE++ copper ports, four 100/1000/2500BASE SFP slots, up to 90W per copper port, 36Gbps switching capacity and 26.78Mpps forwarding. The manufacturer rates the PoE budget at 480W up to 70°C and 400W up to 75°C, with redundant 46–57VDC input; Type 4 90W delivery needs 54–57VDC. Features include static routing, RIP, OSPF, VRRP, STP/RSTP/MSTP, ERPS, 802.1Q VLANs, SNMP and RESTful API. EtherWAN lists a limited lifetime warranty subject to policy; Coremicro displays Special Order status, so confirm current inventory, SFPs and high-power DC supply availability before purchasing.
Eight Gigabit 90W PoE++ Copper Ports
Eight 10/100/1000BASE-T(X) ports support IEEE 802.3bt Type 4, with up to 90W for an individual compatible device and backward compatibility with 802.3af/at. The shared chassis limit is 480W through 70°C or 400W through 75°C; the installation guide also places a 120W limit on each two-port PoE group. Size every connected load and DC supply before deployment.
Four 100M/1G/2.5G SFP Fiber Uplinks
Four tri-speed SFP slots support 100Mbps, 1Gbps and 2.5Gbps optical links with compatible transceivers. This separates powered Gigabit copper edge devices from higher-bandwidth fiber aggregation. Match SFP rate, optical mode, wavelength and distance to the remote port.
Layer 3 Routing and VRRP Redundancy
EtherWAN lists static IPv4 routing, RIP v1/v2, OSPF v2 and VRRP v2 for network segmentation and routing resilience. The published Layer 3 limits include up to 512 hosts and 64 routes. Use the correct routing design and management settings for each deployment.
ERPS Ring and Managed Layer 2 Features
ITU-T G.8032 ERPS, STP, RSTP and MSTP support alternative Ethernet redundancy designs. The switch also provides IEEE 802.1Q VLANs, LACP link aggregation, IGMP snooping and QoS, making it practical for isolating surveillance, industrial control and network management traffic.
SNMP, RESTful API and Secure Administration
Configuration and monitoring options include Web GUI, CLI, SNMP v1/v2c/v3 and RESTful API. EtherWAN also lists HTTPS, SSH, RADIUS/TACACS+, ACLs, system logging and port mirroring. Apply secure credentials and protocols appropriate to the installation rather than exposing legacy management services.
Wide-Temperature DIN-Rail Operation
The fanless IP30 metal enclosure is rated for -40°C to +75°C and measures 62 × 125 × 145 mm. Redundant terminal-block power inputs support industrial installation planning. Supply 54–57VDC when IEEE 802.3bt Type 4 90W output is required, and use a correctly sized power source for all PoE loads.
Industrial IP Surveillance
Power compatible PTZ cameras and other IP endpoints while connecting camera networks through fiber uplinks.
Transportation Networks
Use ERPS, hardened temperature ratings and managed routing in suitable roadside or transit cabinets.

What is the EtherWAN EX78924G-0BT used for?
The EtherWAN EX78924G-0BT is a hardened managed industrial switch for powering eight compatible Gigabit PoE++ endpoints and connecting them to four tri-speed SFP fiber uplinks. It supports Layer 2 and Layer 3 control for surveillance, transport and industrial infrastructure.
How much PoE power can the EX78924G-0BT deliver?
The EX78924G-0BT supports up to 90W on a single IEEE 802.3bt port, but it cannot deliver 90W on all eight ports simultaneously. The total maximum is 480W through 70°C or 400W through 75°C, and the installation guide limits each pair of PoE ports to 120W.
Which DC voltage is required for 90W PoE++?
The EX78924G-0BT accepts redundant 46–57VDC input overall, but IEEE 802.3bt Type 4 output at 90W requires 54–57VDC. The DC power supply must also have adequate capacity for the switch and all powered devices.
What SFP uplink speeds does EX78924G-0BT support?
The EX78924G-0BT provides four separate 100/1000/2500BASE SFP uplinks supporting 100Mbps, 1Gbps and 2.5Gbps. The installed transceivers must match the optical path and desired link speed.
Does the EX78924G-0BT support Layer 3 routing and ring redundancy?
The EX78924G-0BT supports static routes, RIP v1/v2, OSPF v2, VRRP v2 and ITU-T G.8032 ERPS. It also includes VLANs, link aggregation and common spanning-tree protocols for managed industrial topologies.
How does EX78924G-0BT differ from EX78922G-0BT?
Both are EX78900G-series hardened managed Gigabit PoE++ switches with eight powered copper ports. The EX78924G-0BT provides four tri-speed SFP uplinks, while EX78922G-0BT provides two, so the correct choice depends on the required fiber-uplink count.
