4-port Fast Ethernet Server Card
The DFE-580TX is a high-performance, versatile server card designed for very fast server connection. Outfit with 4 Fast
Ethernet ports, the card gives you a 4-port trunk link from a server to a Fast Ethernet switch, providing load-sharing
aggregated bandwidth and redundant backup links, allowing you to cost-effectively run bandwidth-intensive and mission-
