Description
Product Overview
The EtherWAN EX46928A-V-J is a hardened unmanaged 10-port Gigabit PoE+ Ethernet switch with eight 10/100/1000BASE-T PoE+ copper ports and two 1000BASE SFP uplink slots. It supplies a total 120W PoE budget, with up to 30W per powered port subject to two separate 60W four-port allocations. An 18–57VDC input, fanless IP30 metal enclosure and −40°C to +75°C operating range support appropriately protected industrial networking. Select compatible SFP modules and a sufficiently rated DC power supply for the intended installation.
The EtherWAN EX46928A-V-J is an EX46900A Series hardened unmanaged Gigabit Ethernet PoE+ switch offered by Coremicro in Union City, California. The exact V-J configuration provides eight 10/100/1000BASE-T IEEE 802.3af/at PoE+ ports and two 1000BASE SFP slots, an 18–57VDC input, a 120W total PoE power budget (60W for ports 1–4 and 60W for ports 5–8), a fanless IP30 metal chassis, and an operating range of −40°C to +75°C. Coremicro currently labels the listing Special Order and displays an Authorized Dealer designation. The SFP transceivers and external DC power supply included with a specific order, current pricing and warranty coverage should be confirmed before purchase.
Eight Gigabit PoE+ Copper Ports
Eight 10/100/1000BASE-T Ethernet ports support IEEE 802.3af/at power delivery for compatible IP cameras, wireless access points and other powered devices. Each port supports up to 30W within the available group and total PoE limits.
Two Gigabit SFP Fiber Uplinks
The EX46928A-V-J adds two 1000BASE SFP slots for compatible fiber-optic uplinks. Choose the SFP transceivers separately according to distance, fiber type, wavelength and host compatibility; their inclusion in the package is not confirmed.
120W Total PoE Power Budget
A shared 120W PoE budget supports powered endpoints, but it is split into 60W for ports 1–4 and 60W for ports 5–8. Check each four-port group rather than relying on the 120W aggregate rating alone.
18–57VDC Industrial Power Input
The wide 18–57VDC input range supports suitable industrial DC power systems and includes reverse-polarity protection. The external power supply must accommodate both the switch consumption and connected PoE loads.
Hardened Fanless IP30 Construction
The fanless metal enclosure operates from −40°C to +75°C under the published conditions. Install it in a protected cabinet or location compatible with its IP30 ingress rating and the environmental limits of connected equipment.
Unmanaged Gigabit Ethernet Switching
Store-and-forward operation, automatic negotiation, auto MDI/MDIX, and IEEE 802.3x full-duplex flow control support straightforward network expansion. This is an unmanaged switch, not a device with a managed VLAN or web-configuration interface.
Jumbo Frames and Ethernet Capacity
The series specifies support for jumbo frames up to 9.6KB, an 8K MAC address table, and a 4Mbit packet buffer. Confirm the rest of the network path supports any larger-frame configuration used by connected devices.
Alarm Relay and Installation Options
A normally open/normally closed alarm relay allows connection to appropriate monitoring equipment. DIN-rail mounting hardware is listed as included, while rack and panel mounting options should be checked for the required accessory kit.

Eight Powered Copper Ports, Two SFP Uplinks
Use the PoE+ copper ports for compatible cameras, access points and communications equipment, while the two 1000BASE SFP slots provide a path to remote network infrastructure through supported optical modules.
Industrial sites must provide the correct DC power supply, suitable protection for the IP30 enclosure, and adequate power capacity for all connected devices.
Industrial IP Camera Networks
Connect compatible PoE+ IP cameras to the eight powered RJ45 ports, then use supported SFP optics for fiber uplinks. Budget camera power against the 60W limit of each four-port group.
PoE Wireless Access Points
Supply power and Gigabit Ethernet connectivity to compatible wireless access points in protected industrial areas. Confirm each access point's PoE class and the aggregate load.
VoIP and Ethernet Endpoints
Support compatible PoE phones and other industrial Ethernet devices without managed-switch configuration. Verify the features required by the wider network before installing an unmanaged switch.
Wide-Temperature Fiber Uplinks
Connect separated equipment cabinets in appropriately rated industrial sites using the two Gigabit SFP ports. Select optical transceivers and fiber paths for the exact reach and environmental conditions.
Industrial Integrators
For specifying rugged unmanaged Gigabit switching with PoE+ and fiber uplinks.
Security Installers
For matching IP camera power requirements to the switch's two 60W PoE groups.
Network Engineers
For selecting compatible Gigabit SFP modules, DC supplies and fiber paths.
Remote Site Operators
For deploying Ethernet equipment in suitably protected wide-temperature environments.
