Advantech EKI-2526M – 4+2 Port PoE Industrial Ethernet Switch

Key Specifications & Features

1. Port Configuration & PoE Capability:

   • 4 x 10/100BASE-TX RJ45 PoE Ports: These are the key feature. They deliver both data and power.

     • PoE Standard: Typically IEEE 802.3af (PoE), providing up to 15.4W per port.

     • PoE Budget: The total power budget is a critical spec (e.g., 56W). You must ensure the combined power draw of all connected PoE devices does not exceed this.

   • 2 x 10/100BASE-TX RJ45 Uplink/Data Ports: Standard non-PoE ports for connecting to the network backbone or non-PoE devices like a PLC or HMI.

2. Unmanaged & Simple:

   • Plug-and-play operation. The PoE function is automatic—the switch detects a compatible PD (Powered Device) and delivers power.

3. Industrial Ruggedness:

   • Operating Temperature: -10°C to 60°C or -40°C to 75°C depending on the specific variant/suffix. Always verify! PoE switches often have a slightly reduced temperature range due to the heat generated by power circuitry.

   • Power Input: 24 to 48 VDC or 48 VDC for PoE. It has a primary power input for the switch itself.

   • Protections: Includes Ethernet surge protection and short-circuit/overload protection on PoE ports.

4. PoE-Specific Features:

   • Automatic Detection & Classification: Identifies PoE devices and allocates power accordingly.

   • Per-Port Protection: Isolates a short-circuit on one PoE port without affecting others.

Typical Use Cases (Where It Excels)

This switch is purpose-built for deploying power-requiring IP devices in industrial settings:

1. Industrial Surveillance Systems: The prime use case. Powering and connecting 4 IP cameras around a machine, warehouse aisle, or outdoor perimeter from a single, protected cabinet.

2. Wireless Infrastructure: Powering industrial Wi-Fi access points or wireless mesh nodes on the factory floor or in a yard.

3. Compact IP Device Clusters: Connecting a mix of PoE and non-PoE devices in a panel—e.g., 2 cameras (PoE), a VoIP phone (PoE), a barcode scanner (Data), and a network printer (Data).

4. Simplified Installation: Eliminates the need to run separate AC power lines to each device, drastically reducing installation cost and complexity, especially in hard-to-reach or hazardous areas.

   
   

   
   

   The Advantech EKI-2526M is a 6-port, unmanaged industrial Ethernet switch with 4 PoE ports. It combines data switching with the ability to power compatible devices like IP cameras, wireless access points, and VoIP phones over the same Ethernet cable, significantly simplifying installation in harsh environments.
