10/100Base-TX
Twisted Pair
Ports
The AT-FS705L Fast Ethernet switch features five twisted pair ports. The
features of the twisted pair ports are explained in the following sections.
Type of Connector
All twisted pair ports feature 8-pin RJ-45 connectors. (For the port pinouts,
refer to “RJ-45 Twisted Pair Port Connectors” on page 35.)
Speed
The ports are 10Base-T, and 100Base-T compliant and are capable of 10
Mbps and 100 Mbps speeds. The ports are IEEE 802.3u Auto-Negotiation
compliant. With Auto-Negotiation, the switch automatically matches the
highest possible common speed between each switch port and each endnode. For example, if an end-node is capable of only 10 Mbps, the switch
sets the port connected to the end-node to 10 Mbps.
Duplex Mode
Each twisted pair port on the switch can operate in either half- or fullduplex mode. The twisted pair ports are IEEE 802.3u-compliant and will
Auto-Negotiate the duplex mode setting.
In order for the switch to set the duplex mode for each port correctly,
the end-nodes that you connect to the switch ports also need to be
configured for Auto-Negotiation. Otherwise, a duplex mode
mismatch can occur, affecting network performance. For further
information, refer to “Duplex Mode” on page 19.
Type of Cabling
15
Chapter 1: Product Description
For 10 Mbps operation, Category 3 or better 100 ohm shielded or
unshielded twisted pair cabling is required. For 100 Mbps operation,
Category 5 and Enhanced Category 5 (5E) 100 ohm shielded or
unshielded twisted pair cabling is required.
Maximum Distance
Each twisted pair port has a maximum operating distance of 100 meters
(328 feet).
Auto MDI/MDI-X
All of the twisted pair ports on the switch are auto-MDI and IEEE 802.3abcompatible. The ports use the auto-MDI feature to automatically configure
themselves as MDI or MDI-X when connected to an end-node.
Consequently, you can use a straight-through twisted pair cable to
connect any network device to a port.
System and Port
LEDs
The system and port LEDs on the front panel of the AT-FS705L switch
display status information. Each port has three LEDs. Table 2 describes
the system and port LEDs on the AT-FS705L Fast Ethernet switch.

Chapter 1: Product Description
A Few Ethernet Switching Basics
An Ethernet switch interconnects network devices, such as workstations,
printers, routers, and other Ethernet switches, so that they can
communicate with each other by sending and receiving Ethernet frames.
MAC Address
Table
Every hardware device on your network has a unique MAC address. This
address is assigned to the device by the device’s manufacturer. For
example, when you install a Network Interface Card (NIC) in a computer
so that you can connect it to the network, the NIC already has a MAC
address assigned to it by its manufacturer.
The AT-FS705L Fast Ethernet switch can contain up to 1,024 entries in its
MAC address table. The switch uses the table to store the MAC addresses
of the network end-nodes connected to the ports, along with the port
number on which each address was learned.
A switch learns the MAC addresses of the end-nodes by examining the
source address of each packet received on a port. It adds the address and
port on which the packet was received to the MAC table if the address had
not already been entered in the table. The result is a table that contains all
the MAC addresses of the devices that are connected to the switch’s
ports, and the port number where each address was learned.
When the switch receives a packet, it also examines the destination
address and, by referring to its MAC address table, determines the port on
which the destination end-node is connected. It then forwards the packet
to the appropriate port and on to the end-node. This increases network
bandwidth by limiting each frame to the appropriate port when the
intended end-node is located, freeing the other switch ports for receiving
and transmitting data.
If the switch receives a packet with a destination address that is not in the
MAC address table, it floods the packet to all the ports on the switch. If the
ports have been grouped into virtual LANs, the switch floods the packet
only to those ports which belong to the same VLAN as the port on which
the packet was received. This prevents packets from being forwarded into
inappropriate LAN segments, increasing network security. When the
destination end-node responds, the switch adds its MAC address and port
number to the table.
If the switch receives a packet with a destination address that is on the
same port on which the packet was received, it discards the packet
without forwarding it on to any port. Since both the source end-node and
the destination end-node for the packet are located on the same port on
the switch, there is no reason for the switch to forward the packet.
18
AT-FS705L Fast Ethernet Switch Installation Guide
Note
Duplex Mode Duplex mode refers to how an end node receives and transmits data. If an
end node can receive or transmit data, but not both simultaneously, it is
operating in what is referred to as half-duplex mode. If an end node can
both receive and transmit data simultaneously, the end node is operating
in full-duplex mode. Naturally, an end node capable of operating in fullduplex can handle data much faster than an end node that can only
operate in half-duplex mode.
The twisted pair ports on the AT-FS705L switch can operate in half- or fullduplex mode for 10/100 Mbps. They are IEEE 802.3u-compliant and use
Auto-Negotiation to set the duplex mode setting for you automatically.
In order for a switch port to successfully Auto-Negotiate its duplex
mode with a 10 or 100 Mbps end-node, the end-node should also be
configured for Auto-Negotiation. Otherwise, a duplex mode
mismatch can occur. A switch port using Auto-Negotiation defaults
to half-duplex if it detects that the end-node is not using AutoNegotiation. This results in a mismatch if the end-node is operating
at a fixed duplex mode of full-duplex.
Store and
Forward
Backpressure and
Flow Control
An AT-FS705L 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 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.
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
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 duplex mode of the end-node and switch port. A twisted
pair port operating in 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 an end-node to stop sending data,
wait for a brief period of time, and then retransmit the same data. Once the
switch is ready to receive data again, the switch stops forcing collisions.
This is referred to as backpressure.
19
Chapter 1: Product Description
A port operating in full-duplex mode uses PAUSE frames, as specified in
the IEEE 802.3x standard, to stop the transmission of data from an endnode. Whenever the switch wants an end-node to stop transmitting data, it
issues this frame. The frame instructs the end-node to cease transmission
for a period of time specified within the frame. The switch continues to
issue PAUSE frames until it is ready again to receive data from the endnode. This is referred to as flow control.

Figure 6. Connecting the AT-FS705L Twisted Pair Data Cables
When connecting a twisted pair cable to a port, observe the following
guidelines:
An RJ-45 connector should fit snugly into the port on the switch.
The tab on the connector should lock the connector into place.
The ports on the switch are auto-MDI/MDI-X. You can use a
straight-through twisted pair cable to connect any type of network
device to a port on the switch.
The network should not contain data loops, which can adversely
affect network performance. A data loop exists when two or more
network devices can communicate with each other over more than
one data path.

This chapter contains information on how to troubleshoot the switch in the
event a problem occurs.
If you are still unable to resolve the problem after following the
instructions in this chapter, contact Allied Telesis Technical Support
for assistance. Refer to “Contacting Allied Telesis” on page 11.
Check the POWER LED on the front of the switch. If the LED is OFF,
indicating that the unit is not receiving power, do the following:
Verify that the power cord is securely connected to the power source
and to the AC connector on the back panel of the switch.
Verify that the power outlet has power by connecting another device
to it.
Try connecting the unit to another power source.
Try using a different power cord.
Verify that the voltage from the power source is within the required
levels for your region.
Verify that the LINK/ACT LED for each port is ON. If a LINK/ACT LED is
OFF, do the following:
Verify that the end-node connected to the port is powered ON and is
operating properly.
Verify that the twisted pair cable is securely connected to the port on
the switch and to the port on the end-node.
Ensure 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 and
Category 5E for 100 Mbps operation.
