Introduction
24 × 10/100Mbps ports Fast Ethernet Switch
Ether-FSH2400N Fast Ethernet Switch is an auto-sensing and auto-negotiating 10/100ABSE-TX
Fast Ethernet Switch. Its twenty-four 10/100Mbps station ports provide 10/100Mbps connections to
Ethernet/Fast Ethernet network.
Ether-FSH2400N’s unique switching fabric provides full wire speed for all ports. With
auto-sensing, Ether-FSH2400N automatically detects the speed of the devices you plug into, and
routes the incoming data to its destination. Its auto-negotiating function allows existing devices
running at different speeds to communicate easily within the same network.
Store-and-Forward Architecture against Packet Loss
When network is under heavy traffic, the shared memory buffer in the switching devices might yield
incorrect detections due to overfed memory buffer. This setback can happen either when data is
transmitted in IEEE802.3x Full Duplex or Back Pressure Flow Control mode. To solve this problem,
Ether-FSH2400N utilizes a fixed memory buffer allocation with Store-and-forward transmission to
ensure an effective buffer allocation for each port.
Store-and-forward transmission controls data flow from transmitting to receiving nodes with the
receiving buffer threshold adjusted to an optimal value, thus guaranteeing against all possible packet
losses.
Active Flow Control
Ether-FSH2400N Fast Ethernet Switch implements in full duplex mode a flow control that is
compliant with the IEEE 802.3x standard. While in half duplex mode, it employs an optional Back
Pressure Flow Control to stall the incoming data when port buffers are saturated. With this flow
control mechanism, it can be ensured that frames dropped during transmission are reduced to a
minimum.
Full Wire Speed
Ether-FSH2400N’s Full Wire Speed feature provides high-end performance for departmental and
workgroup environments at a fraction of the cost of similar devices. Typically, this feature was
found only in high-end switches designed to handle huge corporate networks. With bandwidth needs
and network efficiency concerns, Ether-FSH2400N’s switching fabric design is the perfect answer
for bandwidth enhancement solution.

System/Port Status Information at a Glance
There are 2 sets of LEDs on the front panel: System LEDs and Station Port LEDs.
The System LEDs consist of the Power, ower LED shows Power On/Off status of the switch.
The Station Port LEDs reveal the link status, half/full duplex transmission, 10/100Mbps speed
mode and the collision status of each station port.
For detailed LED information, refer to Chapter 5, LED Indicators.
