Industrial PoE Connectivity for Harsh, Space-Limited Sites
The IES300-4P2F is an unmanaged 4 Port Gigabit Industrial PoE Switch with 2 SC Fiber Ports, built for network points where ordinary office switches may struggle. It provides four 10/100/1000Base-T RJ45 ports for PoE cameras, wireless access points, intercoms, sensors, and other Ethernet devices, plus two 1.25G 1000Base-X SC fiber ports for long-distance uplinks. For an installer or network administrator, this layout keeps copper device connections close to the field equipment while fiber carries traffic back to a control room, cabinet, or main distribution switch.
Every RJ45 port supports IEEE 802.3af/at Standard PoE and can deliver up to 25.4W per port. The switch checks whether a connected device supports the PoE standard before applying power, helping protect ordinary non-PoE equipment from accidental power delivery. Auto-negotiation selects 10, 100, or 1000Mbps, while auto MDI/MDI-X removes the need to worry about cable type during installation. Line-speed forwarding and store-and-forward switching keep camera, control, and monitoring traffic moving without unnecessary configuration work.
Practical Reliability for Industrial Networks
Industrial installations often face heat, cold, electrical noise, vibration, and limited maintenance access. This DIN-Rail industrial PoE switch uses a fanless metal housing and natural cooling, so there is no fan to collect dust or become a common failure point. The operating temperature range is -40°C to +85°C, making it suitable for roadside cabinets, factory floors, building service rooms, and outdoor enclosures with suitable environmental protection.
Dual redundant DC power inputs allow the network to remain powered if one supply path fails. Reverse-polarity protection and overload protection provide an extra safeguard during field wiring and maintenance. Surge and EMC protection help the switch handle induced voltage and electrical interference found around motors, traffic equipment, and industrial control systems. The IP40 metal enclosure, compact 139mm × 108mm × 50mm footprint, and weight below 0.6kg make it easy to install in a crowded control cabinet without adding a large heat load.
Simple Deployment, Predictable Maintenance
This unmanaged Gigabit PoE switch requires no IP address, software license, or switch configuration. Connect the fiber uplink, plug in the copper devices, and the link and PoE indicators provide a quick visual check. That matters for contractors commissioning multiple cabinets or IT teams supporting remote sites with limited on-site expertise. The 16K MAC address table, 10Gbps switching bandwidth, 5.952Mpps forwarding rate, 2MB packet buffer, and support for jumbo frames up to 10KB provide practical capacity for small industrial networks and monitoring systems.
The two SC fiber ports can be specified for multimode transmission up to 550m or 2km, or single-mode links from 2km to 100km, depending on the selected optical configuration. This makes the 4 Port Gigabit Industrial PoE Switch with 2 SC Fiber Ports a useful fit for factory lines, road traffic control, building automation, industrial IoT gateways, and data center monitoring extensions. It is best suited to teams that need dependable PoE and fiber connectivity without the cost or operating workload of a managed switch. A three-year warranty supports planned deployment and replacement management.
