10/100 Mbps Twisted Pair Ports  
The twisted pair ports on the switch are labelled 1X through 7X, 8MDI-X and  
8MDI. The features of the twisted pair ports are explained in the following  
sections.  
Type of Connector  
The twisted pair ports have RJ-45 connectors.  
Speed  
These ports are compliant with the 10Base-T and 100Base-TX standards and  
are capable of either 10 Mbps or 100 Mbps operation. The ports are IEEE  
802.3u Auto-negotiation-compliant, meaning the speed for each port is set  
automatically by the switch after determining the speed of the end node  
connected to the port. Auto-negotiation is designed to ensure that each port on  
the switch and each end node are operating at the same speed and that they  
are communicating at the highest possible common speed of the devices.  
Duplex Mode  
The twisted pair ports can operate in either half- or full-duplex operation. Just  
as with speed, the ports use Auto-negotiation to set the duplex mode. If the  
end node is capable of full-duplex mode, the port is set to full-duplex. If the  
end node is capable of only half-duplex, the port is set to half-duplex. For an  
explanation of duplex mode, refer to the section Duplex Modeon page 8.  
Cabling  
The RJ-45 ports on the switch can use shielded or unshielded twisted pair  
cable. The categories of twisted pair cabling used in Ethernet networks are  
Category 3, 4, and 5. The main difference between the categories relates to  
their attenuation, which is a measurement of signal loss over the length of the  
cable. All cables experience attenuation, where the signal loses strength the  
longer the cable. The lower the loss of signal, the lower the attenuation.  
Of the three categories, Category 3 has the highest attenuation, meaning that  
it has the highest signal loss. It is adequate for 10 Mbps operation, but should  
never be used for 100 Mbps network operations. The higher speed requires  
Category 5. If you are installing a new network with end nodes operating at 10  
Mbps, it is recommended that you install Category 5 instead of Category 3.  
This will save you the trouble of having to install new twisted pair cabling  
should you later upgrade your end nodes to 100 Mbps.  
3
 
         
Maximum Distance  
The maximum distance of a twisted pair cable is 100 meters (328 feet). Cable  
lengths that exceed this limit can result in poor or erratic network  
performance.  
Ports 1X to 7X MDI-X Configuration  
An RJ-45 twisted pair port on a 10 Mbps or 100 Mbps Ethernet network  
device can be wired as either MDI or MDI-X. Twisted pair ports on personal  
computers, routers, and bridges are typically wired as MDI. Twisted pair  
ports on switches and hubs are usually MDI-X.  
When connecting two network devices together, you need to use straight-  
through twisted pair cabling when connecting two dissimilar ports together,  
such as an MDI port to an MDI-X port. To connect two similar ports together,  
such as an MDI port to an MDI port, you use a crossover twisted pair cable.  
Ports 1X through 7X on the AT-FS709FC are configured as MDI-X. This  
means that if you are connecting a computer, router, or bridge to one of these  
ports, you probably need to use a straight-through twisted pair cable.  
If you decide to connect another Ethernet switch to one of these ports, or a  
hub, then you will probably need to use a crossover cable.  
Port 8MDI and Port 8MDI-X  
There are two Port 8s. One port is configured as MDI and the other as MDI-X.  
To connect a switch or hub to Port 8, connect it to Port 8MDI. When  
connecting a workstation or server to Port 8, use Port 8MDI-X.  
Note  
You can use either Port 8MDI or Port 8MDI-X. You cannot use both  
ports at the same time.

AT-FS709FC Series Installation Guide  
100 Mbps Fiber Optic Port  
The AT-FS709FC Series switch features one fiber optic port. You can use the  
fiber optic port to connect the switch to another switch or other end node over  
large distances.  
Type of Connector  
The AT-FS709FC Series switches come with a variety of fiber optic  
connectors. Contact your Allied Telesyn International sales representative for  
a list of available connector types.  
Speed  
The fiber optic port is compliant with the 100Base-FX standard and has a  
fixed operating speed of 100 Mbps. This speed cannot be changed; the end  
node that you connect to the fiber optic port on the switch must also be able to  
operate at 100 Mbps.  
Duplex Mode  
The fiber optic port is able to operate in full-duplex mode only. The end node  
that you connect to this port must also be capable of full-duplex operation. For  
an explanation of duplex mode, refer to Duplex Modeon page 8.  
Cabling  
There are two basic types of fiber optic cabling used in Ethernet networks:  
multimode fiber and single-mode fiber. Multimode fiber is for shorter  
distances, typically not more than 2 kilometers (1.25 miles). Single-mode is for  
longer distances. The fiber optic port on the Ethernet switch has a maximum  
operating distance of 2 kilometers (1.25 miles) and is designed to be used with  
either 54/125 or 60/125 micron core/cladding multimode cable.  
Note  
Do not use single-mode fiber optic cable with the fiber optic port on the  
AT-FS709FC switch.  
5
 
         
Maximum Distance  
The maximum operating distance of the fiber optic port on the AT-FS709FC  
Series Ethernet switch is 2 kilometers (1.25 miles). Cable lengths that exceed  
this limit can result in poor or erratic network performance.  
Note  
The fiber optic port on the network device that you intend to connect to  
the AT-FS709FC Series Ethernet switch must have the same operating  
characteristics as the fiber optic port on the switch. For example, the  
maximum operating distance and operating wavelength of the end  
nodes fiber optic port should be the same as the switchs fiber optic port.  
For the technical specifications of the fiber optic port on the switch, refer  
to Technical Specificationson page 21.

AT-FS709FC Series Installation Guide  
Introduction to Ethernet Switching  
An Ethernet switch is designed to manage the flow of data between the  
various devices that are connected to its ports.  
MAC Address Table  
The heart of an Ethernet switch is the Media Access Control (MAC) address  
table. Every device that you attach to an Ethernet network has a MAC  
address. This address is assigned to the device by the devices manufacturer.  
For example, every Network Interface Card (NIC) that you install into your  
network computers has a MAC address that was assigned to it by the cards  
manufacturer.  
A switchs MAC address table is a list of the MAC addresses of the devices  
that are connected to its ports. The switch uses this table to direct data frames  
to their appropriate destination end nodes, and in some cases, to discard  
frames that it receives. The switch creates the MAC address table by  
examining the data frames that it receives on its ports. Each frame is  
examined for its source address: that is, the MAC address of the end node that  
sent the frame. The switch checks to determine whether the address is  
already in its MAC address table. If it is not, the switch adds the address to  
the table along with the port number on which the frame was received. The  
result is a table that contains a list of all the MAC addresses of end nodes that  
have sent frames through the switch and the ports on the switch to which the  
end nodes are connected.  
The switch also checks the destination MAC address of each frame it receives.  
The destination address is the MAC address of the end node to which the  
frame is intended. If the address is in the table, the switch directs the frame  
directly to the port where the end node is located. This helps to ensure that  
end nodes will only receive traffic that is intended for them and not have to  
deal with traffic intended for other end nodes.  
If the destination address is not in the MAC address table, the switch  
broadcasts the frame to all switch ports. When the destination node responds,  
the switch will be able to match the address to a port so that the next time a  
frame is destined to that particular end node, the switch will be able to  
forward the frame to the correct port instead of having to broadcast the frame  
to all ports.  
In some cases, a switch will even discard a frame. If the switch receives a  
frame that is destined to a node on the same port on which the frame was  
received, the switch discards it.  
7
 
   
The MAC address table in the AT-FS709FC Series Ethernet switch can store  
up to 4,000 MAC addresses. To prevent the table from becoming filled with  
addresses of end nodes that are no longer active, the switch has a MAC  
address aging timer. This timer will delete a MAC address from the table if it  
does not see a frame from the end node with that address on any port after  
five minutes (300 seconds). The aging timer also helps to ensure that the table  
is correct should an end node be moved from one port on the switch to another  
port.  
Store and Forward  
The Ethernet switch uses store and forward as the method for receiving and  
transmitting frames. When a 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 its memory buffer. It then  
examines the frame to determine if it is a valid frame. Invalid frames, such as  
fragments, are discarded by the switch. In this manner, the switch ensures  
that only valid frames are transmitted out its ports and that damaged frames  
are not propagated on your network.  
Duplex Mode  
Duplex mode determines the method by which an end node receives and  
transmits of data. If an end node can receive or transmit data, but not both at  
the same time, the end node is operating in what is referred to as half-duplex  
mode. If an end node can both receive and transmit data simultaneously, the  
node is operating in full-duplex mode. Naturally, a node capable of operating  
in full-duplex can handle data much faster than a node that can only operate  
in half-duplex.  
Each twisted pair port on an AT-FS709FC Series switch can operate in either  
half- or full-duplex mode. The twisted pair ports are IEEE 802.3u-compliant  
and will Auto-negotiate the duplex mode setting. If the end node connected to  
a twisted pair port on the switch is capable of full-duplex operation, the switch  
sets the twisted pair port to full-duplex. If the end node is capable of only half-  
duplex, the port is set automatically to half-duplex.  
The duplex mode for the fiber optic port is set to full-duplex. This cannot be  
changed. The end node that you connect to the fiber optic port must be capable  
of full-duplex operation.

AT-FS709FC Series Installation Guide  
Flow Control  
In order for an Ethernet switch to maintain the orderly movement of data  
between the end nodes that are connected to its ports, it will occasionally need  
to signal an end node to stop sending data. This can occur under several  
situations. For example, when two end nodes are operating at different  
speeds, the switch, while transferring data between the nodes, might need to  
instruct the faster end node to stop transmitting data to allow the slower end  
node to catch up. An example of this situation would be when a server  
operating at 100 Mbps is sending data to a workstation operating at only 10  
Mbps.  
Another situation when a switch might need to stop the transmission of data  
from an end node is if two end nodes are vying for the same switch port at the  
same time. An example of this would be if two workstations were attempting  
to send data to the same network printer simultaneously. The switch could  
allow only one workstation to send data out the port to the printer, and it  
would need to instruct the other workstation to delay data transmission.  
To some degree, these conflicts are minimized by the switchs port buffers.  
These buffers are used to store data when a port is either already busy  
transmitting other data or when a transmitting port on a switch is operating  
at a slower speed than the port on the switch receiving data.  
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 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.  
A twisted pair port or fiber optic port operating at 100 Mbps and full-duplex  
mode uses PAUSE frames, as specified in the IEEE 802.3x standard.  
Whenever the switch wants an end node to stop transmitting data, it issues a  
this frame. The frame simply instructs the end node to cease transmission.  
The switch continues to issue PAUSE frames until it is ready to again receive  
data from the end node.

Network Topologies  
AT-FS709FC Series Ethernet switch supports a variety of network topologies.  
The first topology shown in Figure 3 is of a power workgroup. Each end node is  
connected directly to a port on an AT-FS709FC switch, giving each node a  
dedicated 10 Mbps or 100 Mbps link.

In the topology illustrated in Figure 4, an AT-FS709FC is used to connect  
together eight 10/100 Mbps Ethernet hubs. This type of topology is often  
referred to as a collapsed backbone topology. The switch functions as the focal  
point for all workgroup hubs in your network, acting as a bridge between the  
different workgroups. The switch transfers an Ethernet frame from hub to  
hub only when the destination node for the frame is on a different hub than  
the node that originated the frame. This reduces the amount of unnecessary  
data traffic in each workgroup, which frees up bandwidth and improves  
network performance.

AT-FS709FC Series Installation Guide  
If you need to connect together multiple AT-FS709FC Series switches, you  
might again consider constructing a collapsed backbone topology. But rather  
than using an AT-FS709FC switch as the backbone switch, you could use a  
Fast Ethernet switch that has multiple fiber optic ports and connect the  
AT-FS709FC Series switches using the fiber optic ports. Since the fiber optic  
port on the AT-FS709FC Series switch has a maximum operating distance of 2  
kilometers (1.25 miles), you can connect together switches that are physically  
separated by large distances.  
An example of this topology is illustrated in Figure 5. Eight AT-FS709FC  
Series Ethernet switches have been interconnected using an AT-8216FXL  
Fast Ethernet Switch.

4. Power ON the switch by connecting the power cord to the AC power  
connector on the back panel of the switch and by connecting the power cord  
to an appropriate AC power source.  
The PWR LED on the switchs front panel should be ON. If the LED  
remains OFF, refer to Verifying and Troubleshooting the Installationon  
page 20 for assistance.  
Warning  
The power cord is used as a disconnection device. To de-energize  
equipment, disconnect the power cord.  
9
5. Connect the twisted pair cables to the RJ-45 connectors on the switch.  
When cabling the ports, observe the following guidelines:  
Ports 1X through 7X are configured as MDI-X. When connecting a  
device with an MDI port to one of these ports, use straight-through  
twisted pair cabling. When connecting a device with an MDI-X port to  
one of these switch ports, use a cross-over cable.  
You do not need to use a cross-over cable to connect a device to Port 8.  
If the end node has an MDI port, connect the device to Port 8MDI-X on  
the switch. If the end node has an MDI-X port, connect it to Port 8MDI.  
Note  
You can use either Port 8MDI or Port 8MDI-X on the AT-FS709FC  
Ethernet switch. You cannot use both ports simultaneously.  
6. Remove the dust cover from the fiber optic port and connect the fiber optic  
cable to the port. When cabling the port, observe the following guidelines:  
Make sure that the cable connected to the fiber optic receiver port on  
the switch is connected to the transmitter port on the remote end node  
and that the fiber optic transmitter port on the switch is connected to  
the receiver port on the end node.  
The fiber optic port on the network device that you connect to the  
AT-FS709FC Series Ethernet switch must have the same operating  
characteristics as the fiber optic port on the switch. For example, the  
maximum operating distance and operating wavelength of the end  
nodes fiber optic port should be the same as the switchs fiber optic  
port. For technical specifications on the fiber optic port on the switch,  
refer to Technical Specificationson page 21.  
19  
 
7. Power ON the end nodes connected to the ports on the switch.  
8. Check the LINK/ACT LED for each port. The LED should be steady green  
or blinking. If a LINK/ACT LED remains OFF, refer to the next section,  
Verifying and Troubleshooting the Installation, for assistance.  
Verifying and Troubleshooting the Installation

operating properly.  
Check that the twisted pair cable is securely connected to the port on  
the switch and to the port on the end node.  
Make sure that the twisted pair cable does not exceed 100 meters (328  
feet).  
Verify that you are using the appropriate category of twisted pair  
cable: Category 3 or better for 10 Mbps operation and Category 5 for  
100 Mbps operation.  
Check that the LINK/ACT LED for the fiber optic port is steady green or  
blinking. If the LED is OFF, do the following:  
Verify that the end node connected to the port is powered ON and is  
operating properly.  
Check that the fiber optic cable is securely connected to the port on the  
switch and to the port on the end node.

Make sure that the cable connected to the fiber optic receiver port on  
the switch is connected to the transmitter port on the remote end node  
and that the fiber optic transmitter port on the switch is connected to  
the receiver port on the end node.  
Test the attenuation on the fiber cable to ensure that it does not  
exceed acceptable values.  
Verify that you are using the appropriate type of fiber optic cabling  
and that you have not exceeded the allowable maximum distance. For  
information, refer to Twisted Pair Cable and Fiber Optic Cable  
Guidelineson page 17.  
Check that the operating specifications (e.g., wavelength and  
maximum operating distance) of the fiber optic port on the end node  
are compatible with the operating specifications of the fiber optic port
