Description
Product Overview
The EtherWAN EX46908A-0-J is a hardened, unmanaged 8-port Gigabit Ethernet PoE+ switch for industrial networking and compatible IP security installations. Eight 10/100/1000BASE-T copper ports support IEEE 802.3af/at PoE+, with a 120W total power budget split into two 60W four-port groups. The 18–57VDC input, fanless IP30 metal enclosure, and -40°C to +75°C operating range suit properly protected industrial equipment locations. This exact model has no SFP or fiber uplink ports; confirm power-supply sizing and port requirements before ordering.
The EtherWAN EX46908A-0-J is a hardened unmanaged 8-port Gigabit PoE+ Ethernet switch offered by Coremicro. The manufacturer specifies eight 10/100/1000BASE-T copper ports with IEEE 802.3af/at PoE+ (up to 30W per port), a 120W total PoE budget allocated as 60W to ports 1–4 and 60W to ports 5–8, 18–57VDC input, -40°C to +75°C operation, and fanless IP30 metal housing. The model has no built-in SFP or fiber-optic ports. Coremicro lists the product as Special Order and displays an Authorized Dealer designation; confirm supply requirements, available stock, current authorization and warranty conditions before purchase.
Eight Gigabit PoE+ Ports
Eight 10/100/1000BASE-T Ethernet ports provide network connectivity and power over a single cable. IEEE 802.3af/at compatibility supports connected devices that require standard PoE or PoE+ power. This reduces the need for separate power outlets near supported network endpoints.
120W Industrial PoE Budget
The switch provides a total PoE budget of 120W, divided into 60W for ports 1–4 and 60W for ports 5–8. Each PoE port supports up to 30W, subject to the available power budget. Check the combined power requirements of connected devices before deployment.
Wide-Range DC Power Input
An 18–57VDC input range accommodates compatible industrial DC power systems. The design includes reverse-polarity protection. Confirm the selected power supply meets the input requirements and total load of the planned installation.
Hardened Fanless Construction
The fanless metal enclosure helps avoid moving-part wear associated with cooling fans. An IP30 enclosure rating suits protected equipment locations where the installation environment meets the product's protection limits. It is intended for industrial networking rather than exposure to water or dust ingress beyond its rating.
Extended Temperature Operation
The specified operating range is −40°C to 75°C. This supports network installations in industrial facilities and other locations with significant temperature variation. Installation conditions, ventilation clearance, and the power supply must still remain within their respective operating limits.
Unmanaged Gigabit Ethernet Switching
Store-and-forward switching, auto-negotiation, and auto MDI/MDIX simplify standard Ethernet connections. The switch also supports IEEE 802.3x full-duplex flow control and half-duplex backpressure. As an unmanaged switch, it is suited to straightforward network expansion without a managed-switch configuration workflow.
DIN-Rail and Panel Installation
A DIN-rail mounting kit is included. Rack and panel installation are supported with separately specified mounting kits; confirm the needed accessories and cabinet clearances before ordering.
Industrial Network Monitoring
An alarm relay output supports compatible external monitoring circuits and provides normally open and normally closed contacts. Confirm the correct AC or DC contact rating for the specific hardware revision and alarm circuit before wiring.
Copper-Only Port Configuration
This specific model provides eight copper Gigabit Ethernet PoE+ ports and does not include SFP or fiber-optic ports. It is appropriate when the connected devices use copper Ethernet. Fiber uplinks or additional optical connectivity require a different switch configuration or separate network equipment.
