Chapter 1 Overview

The AT-FS705PD is a 5-port Unmanaged Fast Ethernet Switch that includes one Power-Over-Ethernet (POE) port. This switch is considered a Class 1 Powered Device (PD) and can be used in pair with any IEEE 802.3af/D4.3 or later compliant Power Sourcing Equipment (PSE).

This switch offers a range of features and capabilities that can be used in a variety of network configurations and topologies. It also serves the following functions:

❑ Creating small workgroups with dedicated 10 megabits per second

(Mbps) and 100 Mbps links to your network devices, such as workstations, servers, printers, and routers.

❑ Interconnecting Ethernet hubs or switches to provide a bridge

between the different workgroups of your network.

❑ Connecting to other Ethernet switches so that they can be part of a

larger Ethernet network.

❑ Maximizing your existing network by providing full-duplex operation

over a twisted pair port.

❑ Receiving both data and power through its POE port.

The POE port allows data and power be transmitted over the same single twisted pair cable without power sourcing consideration or electric rewires.

The AT-FS705PD switch features five 10/100 Mbps twisted pair ports with one port dedicated for POE operation. Each twisted pair port has an RJ-45 connector with a maximum operating distance of 100 meters (328 feet). The twisted pair port can operate at 10 Mbps or 100 Mbps and in half- or fullduplex mode.

The AT-FS705PD switch can be used on a desktop or mounted on a wall. The switch is easy to install and does not require software configuration or management.

Two ways to power on an AT-FS705PD switch are as follows:

❑ Option 1: Powered by a 24VDC @ 0.3A+ output wall adapter.

Option 1 has higher priority, if both options are connected to the AT-FS705PD, then it is powered by Option 1 and the PWR WALL LED is green. In the same time, the PWR POE LED is either blinking or OFF, which is fully controlled by the Power Sourcing Equipment (PSE).

❑ Option 2: Powered-over-Ethernet on Port 5.

Option 2 will be enabled only if an IEEE 802.3af compliant PSE is connecting to Port 5, and no power plug is inserted in the 24VDC power port.

Caution

POE and power cord are used as disconnection devices: To de-energize equipment, disconnect the POE and the power cord.

Note

The AT-FS705PD Switch is classified as IEEE Std 802.3af-2003, Environment A, where a LAN or LAN segment, with all its associated interconnected equipment, is entirely contained within a single lowvoltage power distribution system and within a single building.

Twisted Pair Ports

The AT-FS705PD switch has five 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.

AT-FS705PD Fast Ethernet Switch Installation Guide

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 the ports are 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 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 between the devices. For example, if an end-node is capable of only 10 Mbps, the switch then sets the port connected to the end-node to 10 Mbps.

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

Each twisted pair port on the AT-FS705PD switch can operate in either halfduplex or full-duplex mode. Since these twisted pair ports are IEEE 802.3ucompliant, the duplex mode can be set automatically through AutoNegotiation. With Auto-Negotiation, if the end-node is capable of full-duplex, the port is set automatically to full-duplex mode. If the end-node is capable of half-duplex, the port is set automatically to half-duplex mode.

Note

In order for a twisted pair port on the AT-FS705PD switch to successfully Auto-Negotiate its duplex mode with an end-node, the endnode should also be using Auto-Negotiation. Otherwise, a duplex mode mismatch can occur. The twisted pair port, using Auto-Negotiation, will default to half-duplex if it detects that the end-node is not using AutoNegotiation. This will result in a mismatch if the end-node is operating at a fixed duplex mode of full-duplex.

Overview

Auto MDI/MDI-X

A 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 twisted pair port on a PC, router, or bridge is typically wired as MDI, while a twisted pair port on a switch or hub is usually MDI-X.

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-FS705PD switch features automatic MDI/MDI-X. The twisted pair port automatically determines the configurations 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.

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, each 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 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 to the switch and the ports on the switch to which the end-nodes are connected.

AT-FS705PD Fast Ethernet Switch Installation Guide

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 end-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 an end-node on the same port on which the frame was received, the switch discards the frame.

The MAC address table in the AT-FS705PD switch can store up to 2,048 MAC addresses. To prevent the table from becoming filled with addresses of endnodes 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 the 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 AT-FS705PD switch supports store and forward switching at Fast Ethernet full-wire speed. Packets entering each port are stored in buffers. Once the full packet is received, the switch will forward or discard the packet, depending on its destination address and error status. This ensures that only error-free packets destined for another segment will be transferred across the switch, reducing network load. For example, if the packet entering from Port 1 is destined for an end-node on Port 2, the switch forwards the frame if the frame does not contain any errors. If the packet from Port 1 is destined for an end-node also connected to Port 1, the packet is discarded.
