The Black Box LIE402A is an unmanaged industrial PoE++ network switch featuring two Gigabit fiber SFP ports and four 10/100/1000-Mbps copper RJ-45 ports. It supports PoE, PoE+, and 60-watt PoE++, includes Directed Switch Mode for efficient multicast traffic management, and offers redundant fiber uplinks. The switch operates in extreme temperatures (-40° to 75° C) and includes remote PoE power reset functionality. It's a Layer 2 switch with TAA compliance and comes with a 2-year limited warranty.
The switch features a total of 6 ports: 4 Gigabit Ethernet PoE++ RJ-45 ports supporting 10/100/1000Base-T connections, plus 2 Gigabit fiber SFP expansion slots for 1000Base-X connectivity. The SFP ports can be used for redundant fiber uplinks or daisy-chaining multiple switches. All RJ-45 ports support Power over Ethernet (PoE, PoE+, and PoE++) capabilities.
The Black Box LIE402A supports multiple IEEE networking standards including IEEE 802.3 (Ethernet), IEEE 802.3af (PoE), IEEE 802.3at (PoE+), and IEEE 802.3bt (PoE++). It operates as a Layer 2 switch and supports both twisted pair and optical fiber media types, offering Gigabit Ethernet technology across all ports.
The switch has dimensions of 5.5" height x 1.5" width x 5.5" depth and weighs approximately 1.70 lb. It's designed with a DIN Rail mountable form factor, making it ideal for industrial installations. The compact size and mounting options make it suitable for various deployment scenarios while maintaining a professional installation profile.
Directed Switch Mode is a traffic management feature that intelligently directs multicast traffic only to the appropriate fiber port. This prevents multicast traffic from flooding other network ports, resulting in more efficient network operation and reduced unnecessary network congestion. This feature is particularly valuable in applications requiring optimized multicast traffic handling.
The switch provides comprehensive PoE capabilities including support for PoE (802.3af), PoE+ (802.3at), and PoE++ (802.3bt) with up to 60 watts power delivery. It can automatically negotiate and deliver the appropriate power level required by connected Powered Devices (PDs). The switch includes a remote PoE power reset function, configurable via DIP-switch, allowing remote power-cycling of all connected PoE devices.
The Black Box LIE402A is designed for harsh industrial environments with an extended temperature range of -40° to 75° C. It's environmentally certified with RoHS, REACH, and WEEE compliance. The hardened design makes it suitable for demanding industrial applications where standard networking equipment might fail due to environmental conditions.
