Fast SwitcHub-2se User’s Guide
1-2 Introduction
Accton’s Smart Extender
Accton’s Fast SwitcHub-2se can boost network bandwidth fourfold (i.e., if
running at 100 Mbps 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 sends 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 the lowest
possible level. In comparison, a bridge or router requires considerably more
time (both of which have to store the entire packet before it can be forwarded).
Consequently, the Fast SwitcHub-2se can 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-
