The Advantech EKI-3725-AE is an industrial, unmanaged Gigabit network switch with five ports, designed for use in demanding environments. It serves as a central connection component in industrial networks, where reliable and stable data transmission under critical conditions is required. The switch supports redundant power supply in the range of 12 to 48 VDC, making it suitable for applications with high requirements for operational reliability. An integrated P-Fail relay enables monitoring of the power supply status and can trigger an external response in case of power failure.

Applications

The EKI-3725-AE is intended for industrial applications such as automation systems, machine control, building automation, or transportation technology. It is particularly suitable where high mechanical and electrical load capacity as well as continuous network connection availability are required. Support for Jumbo frames with a size of up to 9,216 bytes enables more efficient data transmission, especially for large data packets, such as those occurring in video transmissions or large file transfers.

Functions and Equipment in Detail

The switch features integrated loop detection, which protects the network from loop formation that can lead to packet loss or network disruptions. This is particularly important in complex network topologies where multiple connections exist between devices. Support for the IEEE 802.1p QoS protocol enables prioritization of data traffic, ensuring that time-sensitive data, such as video signals, receive higher priority and can be reliably transmitted even under high network load. This function is crucial for applications requiring constant data rates and low latency.

Technology Explained Simply

The EKI-3725-AE operates according to the energy-efficient Ethernet standard IEEE 802.3az. This means that ports without an active connection are automatically switched to an energy-saving mode to minimize power consumption. Additionally, the switch regulates power output to the ports based on the length of the connected Ethernet cable, enabling optimal energy distribution and reducing power losses. This technology is particularly advantageous in large networks where many ports are not continuously used.

Compatibility and Accessories

The switch is designed for use in industrial networks and is compatible with standard Ethernet connections. It can work with other devices that also support the IEEE 802.3az standard. However, the use of Jumbo frames requires that connected devices also support this packet size to achieve optimal performance.

Mounting and Installation

The EKI-3725-AE is designed for mounting in standard 19-inch racks or on a wall. Installation is performed by simply connecting Ethernet cables to the ports. Power supply is provided via the redundant 12–48 VDC connection. No additional configurations or software tools are required, as it is an unmanaged switch that operates without interfering with network settings.

Advantages in Operation

Operation of the EKI-3725-AE is characterized by its robust construction and integrated protection functions such as loop detection and P-Fail relay. Energy efficiency through IEEE 802.3az reduces power consumption and lowers operating costs. Support for Jumbo frames and QoS protocols ensures optimized data transmission, especially in applications with high data traffic or time-critical requirements. The redundant power supply increases device availability and minimizes downtime.
