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 endnode to stop sending data. This can occur under several circumstances. For example, if two endnodes are operating at different speeds, the switch, while transferring data between the end-nodes, might need to instruct the faster

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 endnode 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.

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 AutoNegotiation, 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

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 fullduplex 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 endnode can operate at full-duplex, since the endnode is able to send and receive data simultaneously.

The twisted pair ports on the AT-FS708LE switch can operate in either half-duplex or fullduplex 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 fullduplex mode. If an end-node is capable of halfduplex, the port is set automatically to halfduplex mode.

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 AutoNegotiate 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.

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.

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.

Cascade Topology

Figure 4 illustrates the cascade topology where Port 1 on the AT-FS708LE switch is connected to Port 8 on the AT-FS716E switch. Since Port 1 is wired as auto MDI/MDI-X, a crossover or straight-through Category 5 or better twisted pair cable can be use.
