AT-FS709FC Series Installation Guide

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 Mode” on 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 straight­through 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 Mode” on 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
node’s fiber optic port should be the same as the switch’s fiber optic port.
For the technical specifications of the fiber optic port on the switch, refer
to “Technical Specifications” on 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 device’s 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 card’s
manufacturer.

A switch’s 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 half­duplex, 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 switch’s 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.

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

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.
