XTR-2124-AF - Rack mount XTran node with 24 ports (with FAN)


The XTR-2124-AF is a rack mounted High-Port Density network device which is part of the XTran product family. It combines MPLS-TP transport on the backbone with Layer 2 and Layer 3 features on the Ethernet access ports in an integrated industrial IP20 housing which can be 19” rack mounted and is equipped with forced ventilation. The XTR-2124-AF provides a total of 24 Ethernet ports and 2 serial ports. The XTran Access node has a ruggedized design and is compliant with the EMC standards. XTR-2124-AF nodes can be used to build a stand-alone network, or they can be used as an MPLS access network in combination with modular XTran Core and Aggregation nodes.
