Fast SwitcHub-2se User’s Guide
Accton’s Smart Extender
Accton’s Fast Switch-2se can boost network bandwidth fourfold (i.e., if running at 100Mbps and using full-duplex operation for both ports). It provides one 10/100 Mbps RJ-45 port for 10BASE-T or 100BASE-TX media attachment (which is automatically detected by the switch), and one 100 Mbps fiber optic port for 100BASE-FX media attachment via an SC or ST type connector. Either of these ports can be connected to a subnetwork, or directly to a server or key workstation, as well as set for full or half-duplex operation. Moreover, the fiber optic port can be used to significantly extend your network’s diameter.
Note: The ES3002-TF-SC provides an SC-type fiber connector.
The ES3002-TF-ST provides an ST-type fiber connector.
In addition to partitioning an overloaded network, this switch provides connection between networks based on twisted-pair and fiber optic cabling, and can also be configured to operate in either full-duplex or half-duplex data transfer mode to support the interconnection requirements of high-speed devices.
This switch performs “on-the-fly” cut-through switching, which passes a packet to the other port according to the destination address scanned from the packet header. This technique reduces the latency of packet transmission to 20 microseconds or less. Compared to approximately 800 microseconds for a bridge or 1800 microseconds for a router, both of which have to store the entire packet before it can be forwarded, Accton’s SwitcHubs deliver a quantum improvement in your network's performance.
As a device functioning on the media access control (MAC) layer, the Fast SwitcHub is protocol independent. Full compliance with IEEE802.3 and IEEE802.3u standards makes it transparent to upper-level protocols such as TCP/IP, NetWare, DECnet and XNS. Accton's Smart Extender can link high- speed 100BASE-TX or conventional 10BASE-T networks to the newer
