The M3-PM-LAN24 (also referenced as M3-PM-LAN24G) module provides network switch support in the M3C4G system. The M3-PM-LAN24 module works in both legacy 10/100 M backplane and newer 10/100/1000 M backplane M3C4G systems. It uses ESS 2020 switch technology providing reliable operations under shock and vibration conditions typical for mobile applications. It features 24 Fast Ethernet (FE) (10/100) and two (2) Gigabit Ethernet (GbE) (10/100/1000) ports. All ports are auto-sensing, support at least 10/100M operations and auto-crossover detection.
Four (4) of the 24 FE ports (labeled 20-23) are PoE injected, following the IEEE 802.3at PoE standard with a total of 50 W max combined power.
