Power Supply  
The AT-FS708LE Ethernet Switch uses an  
external power adapter that comes standard  
with the unit.  
Store and Forward  
The AT-FS708LE switch uses store and  
forward as the method for receiving and  
transmitting frames. When an Ethernet frame  
is received on a switch port, the switch does not  
retransmit the frame out the destination port  
until it has received the entire frame and stored  
the frame in a port buffer. It then examines the  
frame to determine if it is a valid frame. Invalid  
frames, such as fragments or runts, are  
discarded by the switch. This insures that only  
valid frames are transmitted out the switch  
ports and that damaged frames are not  
propagated on your network.  
Back Pressure and Flow Control  
In order to maintain the orderly movement of  
data between the end-nodes, an Ethernet  
switch may periodically need to signal an end-  
node to stop sending data. This can occur under  
several circumstances. For example, if two end-  
nodes are operating at different speeds, the  
switch, while transferring data between the  
end-nodes, might need to instruct the faster  
16  
 
     
AT-FS708LE Installation Guide  
end-node to stop transmitting data to allow the  
slower end-node to catch up. An example of this  
would be when a server operating at 100 Mbps  
is sending data to a workstation operating at  
only 10 Mbps.  
How a switch signals an end-node to stop  
transmitting data differs depending on the  
speed and duplex mode of the end-node and  
switch port. A twisted pair port operating at  
100 Mbps port and half-duplex mode stops an  
end-node from transmitting data by forcing a  
collision. A collision on an Ethernet network  
occurs when two end-nodes attempt to transmit  
data using the same data link at the same time.  
A collision causes end-nodes to stop sending  
data. When the switch needs to stop a 100  
Mbps, half-duplex end-node from transmitting  
data, it forces a collision on the data link, which  
stops the end-node. Once the switch is ready to  
receive data again, the switch stops forcing  
collisions. This is referred to as back pressure.  
A port operating at 100 Mbps and full-duplex  
mode uses PAUSE frames, as specified in the  
IEEE 802.3x standard, to stop the transmission  
of data from an end-node. Whenever the switch  
wants an end-node to stop transmitting data, it  
issues this frame. The frame instructs the end-  
node to cease transmission. The switch  
continues to issue PAUSE frames until it is  
ready again to receive data from the end-node.  
This is referred to as flow control.  
17  
 
The AT-FS708LE supports TX Flow Control  
only. This means a PAUSE packet will be  
transmitted to the end-node connection if it  
receives data faster than it can switch the  
packets. The AT-FS708LE does not support RX  
Flow Control, however, and it will not respond  
to PAUSE packets sent to it by an end-node.  
Twisted Pair Ports  
The AT-FS708LE switch has eight 10Base-T/  
100Base-TX twisted pair ports. Each twisted  
pair port features a RJ -45 connector. The  
maximum operating distance for the twisted  
pair ports is 100 meters (328 feet) when  
operating at either 10 Mbps or 100 Mbps.  
Port Speed  
The twisted pair ports are compliant with the  
10Base-T and 100Base-TX standards and are  
capable of either 10 Mbps or 100 Mbps  
operation. Since the ports are IEEE 802.3u  
Auto-Negotiation compliant, the switch will set  
the port speed automatically. With Auto-  
Negotiation, the speed of a port is set  
automatically by the switch after it determines  
the speed of the end-node connected to the port.  
Auto-negotiation is designed to ensure that the  
18  
 
   
AT-FS708LE Installation Guide  
port on the switch and the end-node are  
operating at the same speed and that they are  
communicating at the highest possible common  
speed of the devices.  
Duplex Mode  
Duplex mode refers to the way an end-node  
sends and receives data on the network. An  
end-node can operated in either half- or full-  
duplex mode depending on its capabilities. An  
end-node that is operating in half-duplex mode  
can either send data or receive data, but it  
cannot do both at the same time. An end-node  
that is operating in full-duplex mode can send  
and receive data simultaneously. The best  
network performance is achieved when an end-  
node can operate at full-duplex, since the end-  
node is able to send and receive data  
simultaneously.  
The twisted pair ports on the AT-FS708LE  
switch can operate in either half-duplex or full-  
duplex mode. The switch sets the duplex mode  
automatically through Auto-Negotiation. With  
Auto-Negotiation, if an end-node is capable of  
full-duplex, the port is set automatically to full-  
duplex mode. If an end-node is capable of half-  
duplex, the port is set automatically to half-  
duplex mode.  
19  
 
 
Note  
Since the AT-FS708LE ports operate in  
Auto-Negotiate mode only, the end-nodes  
connected to the AT-FS708LE must also  
be configured to operate in the Auto-  
Negotiate mode. If an end-node is  
configured to a specific duplex in a  
manual mode, it will not respond to the  
Auto-Negotiate protocol from the  
AT-FS708LE. (The speed is determined  
from the link pulses, however, so the  
speed is always detected correctly.) As a  
result, the AT-FS708LE port setting will  
end up at half-duplex. If the end port is  
manually configured to full-duplex, there  
will be a duplex mismatch and data will  
be lost. If the end port is manual  
configured to half-duplex, both ports will  
have the speed and duplex match up  
correctly.  
Auto MDI/MDI-X  
An RJ -45 twisted pair port on a 10 Mbps or 100  
Mbps Ethernet network device can have one of  
two possible wiring configurations: MDI or  
MDI-X. A RJ -45 port on a PC, router, or bridge  
is typically wired as MDI, while a twisted pair  
port on a switch or hubs is usually MDI-X.  
20  
 
 
AT-FS708LE Installation Guide  
To connect two 10 Mbps or 100 Mbps network  
devices together that have dissimilar port  
wiring configurations, such as an MDI to  
MDI-X, you would use a straight-through  
twisted pair cable. To connect two networks  
devices that have the same wiring  
configuration, such as MDI to MDI, you would  
use a crossover cable.  
The AT-FS708LE switch features automatic  
MDI/MDI-X. Each RJ -45 port automatically  
determines the configuration of the port on the  
device to which it is connected and then  
configures itself appropriately. For example, if  
a port on a switch is connected to a port on a  
bridge, which is typically wired as MDI, the  
port on the switch automatically configures  
itself as MDI-X. This feature allows you to use  
either a crossover cable or a straight-through  
cable when connecting a device to a twisted pair  
port.  
21  
 
Network Topologies  
The AT-FS708LE switch can be used in a  
variety of network topologies, such as a  
standalone or cascade. Both topologies are  
described below.  
Standalone Topology  
Figure 3 illustrates the standalone topology  
where each end-node is directly connected  
directly to a 10/100Base-TX port on an  
AT-FS708LE switch. This gives each end-node  
a dedicated 10 Mbps or 100 Mbps link.
