AT-FS708LE Fast Ethernet Switch Overview The AT-FS708LE unit is a 10Base-T/ 100Base-TX Fast Ethernet Switch. The unit provides you with a simple, cost-effective solution for Ethernet switching between endnodes operating at either 10 or 100 Mbps. Figure 1 and Figure 2 show the front and back panels of the switch.
8x 7x 6x 5x 4x 3x 2x 1x Figure 2 Back Panel Key Features The AT-FS708LE Ethernet Switch has the following features: ❑ LEDs for unit and port status ❑ 8 Auto-Negotiating 10/100 Mbps twisted pair ports with RJ-45 connectors ❑ Auto MDI/MDI-X on all ports ❑ IEEE 802.3 and IEEE 802.3u compliant ❑ Store and forward switching mode ❑ MAC address table capacity of up to 4,000 entries ❑ IEEE 802.
AT-FS708LE Installation Guide Status LEDs Refer to Table 1 for a description of the device LEDs. Table 1 LED Functions LEDs Color Description PWR Green Indicates the switch is receiving power. 100M Green Indicates the port is operating at 100 Mbps. OFF Indicates the port is operating at 10 Mbps. Green Indicates a valid physical link on the port. Blinking Indicates data is being transmitted or received on the port. Green Indicates the port is operating in full-duplex mode.
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.
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.
The AT-FS708LE supports RX Flow Control only. This means that it will respond to a PAUSE packet sent to it by an end-node connection if data is transmitted faster than the end-node connection can process. The AT-FS708LE does not support TX Flow Control, however, and a PAUSE packet will not be transmitted to the end-node connection if it receives data faster than it can switch the packets. Twisted Pair Ports The AT-FS708LE switch has eight 10Base-T/ 100Base-TX twisted pair ports.
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.
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.
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.
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.
AT-FS708LE Installation Guide 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.
Note Cascading switches, as shown in Figure 4, can result in data loss between switches if the data rate exceeds 100 Mbps. Symptoms may include inability of certain workstations to “Log-On” to a server or unusually slow data transfer rates between workstations or servers. Planning the Installation This section contains the procedures for installing the unit. Verifying the Package Contents Make sure that the package includes the following items.
AT-FS708LE Installation Guide Selecting a Site Be sure to observe the following site requirements: ❑ Make sure you are placing the device in a dust-free and moisture-free environment. ❑ Do not block the ventilation openings on the unit. Allow at least 10 centimeters (4 inches) of space at the front and back of the unit for ventilation. ❑ Make sure that the unit’s power is accessible and cables can be connected easily.

If a LED is OFF, refer to “Troubleshooting” on page 32. The AT-FS708LE switch is now ready for use. Installing the Unit on a Wall For wall-mount installation, you can position the switch vertically or horizontally on the wall using the keyhole cutouts in the bottom of the switch chassis.
4. Position the switch onto the wall screws with the LEDs either facing up or down. Warning The power cord is used as a disconnection device. To de-energize equipment, disconnect the power cord. 5 5. Plug the power adapter into a power source and then plug the DC power cord into the DC connector on the front panel of the switch. 6. Make sure the PWR LED on the front panel is green. If the LED is OFF, refer to “Troubleshooting” on page 32. 7.
