General Description The S18e provides 16*10/100/1000Mbps Gigabit ports and 2*SFP (mini GBIC) ports, making it an excellent choice for a fast and reliable networking infrastructure. The store-and-forward architecture filters errors and forwards packets in a non-blocking environment. Flow control ensures the accuracy of the data transmitted. The 802.3x and back pressure flow control mechanisms work respectively for full and half duplex modes. The two mini GBIC ports allow you to add fiber connectivity for long-distance communication.
