MM2-4TX1 is a four-port Fast Ethernet media module for Belden Hirschmann MICE modular switches, providing 4 x 10/100BASE-TX RJ45 ports in the MICE media-module family. The ports support auto-negotiation and auto-polarity with auto-crossing, enabling flexible cable wiring while delivering up to 100 Mbps per port in Ethernet networks. Power is supplied via the backplane of the MICE switch, and the module typically consumes about 0.8 W. The standard MM2-4TX1 operates from 0 °C to +60 °C, while the MM2-4TX1-EEC variant extends to -40 °C to +70 °C (part numbers 943 722-101 and 943 722-051 respectively).
