13 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 end- nodes operating at ei ther 10 or 100 Mbps.
14 Figure 2 Back Panel Key Features The AT-FS708LE Ethern et Switch has the following features: ❑ LEDs for unit a nd port status ❑ 8 Auto-Negotia ting 10/100 Mbps twisted pair ports with RJ-45 connec tors ❑ Auto MDI/MDI-X on all ports ❑ IEEE 802.
AT-FS708LE Instal lation Guide 15 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 OFF Indicates the por t is operating at 100 Mbps.
16 Power Supply The AT-FS708LE Ethern et Switch uses an external power adapter that comes standard with the unit. Store and Forward The AT-FS708LE swit ch uses store and forward as the method for receiving and transmitting fr ames.
AT-FS708LE Instal lation Guide 17 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.
18 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.
AT-FS708LE Instal lation Guide 19 port on the switch and the end-node are operating at the same sp eed and that they are communicating at the highes t possible common speed of the devices. Duplex Mode Duplex mode refers to the way an end-node sends and receives data on the network.
20 Note Since the AT-FS708LE ports operate in Auto-Negotiate mode only, the end-nodes connected to the AT-F S708LE must als o be configured to operate in the Auto- Negotiate mode. If an end-node is configured to a spec ific duplex in a manual mode, it will not respond to the Auto-Negotiate protocol from the AT-FS708LE.
AT-FS708LE Instal lation Guide 21 To connect two 10 Mbps or 100 Mbps network devices together that have dissimilar port wiring configuration s, such as an MDI to MDI-X, you would use a strai ght-through twisted pair cable.
22 Network Topologies The AT-FS708LE switch can be used in a variety of network to pologies, such as a standalone or cascade. Both topologies are described below. Standalone Topolog y Figure 3 illustrates the standalone topology where each end-node is directly connected directly to a 10/1 00Base-TX port on an AT-FS708LE switch.
AT-FS708LE Instal lation Guide 23 Cascade Topology Figure 4 illustrates the cas cade 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.
24 Note Cascadin g switche s, as sh own in Figure 4, can result in data loss between switches if the data rate exceeds 100 Mbps. Symptoms may i nclude inability of certain workstations to “Log-On” to a server or unus ually slow data transfer rates between workst ations or servers.
AT-FS708LE Instal lation Guide 25 Selecting a Site Be sure to observe the following site requirements: ❑ Make sure you are placing the device in a dust-free and moistu re-free environment. ❑ Do not block the vent ilation openings on the unit. Allow at least 10 centimeters (4 inches) of space at the front and back of the unit for ventilation.
26 Table 2 10Base-T/100Base-TX Twisted Pair Port Cabling Spec if icatio ns Reviewing Safety Guidelines Please review the follow ing safety guidelines before you begin to install the device. Warning Power cord is used as a disconnection device: To de- energize equipment, disconnect the power cord.
AT-FS708LE Instal lation Guide 27 Caution Pluggable Equipment : The socket outlet should be installed near the equipment and should be easily accessible. 6 Caution Air vent s : The air vents on the unit must not be blocked and must have free access to the room ambien t air for cooling.
28 Installing the Unit on a Desktop To wall-mount the switch on a wall, refer to “Installing the Unit on a Wall” on page 29. To install the switch on the desktop, perform the following procedure. 1. Attach the four self-adhesive rubber feet to the bottom of the device , positioning them in the indentations.
AT-FS708LE Instal lation Guide 29 6. Power ON the end-nodes connected to the switch. 7. Check that the LNK/ACT LED for each port on the switch is green. If a LED is OFF, refer to “Troubleshooting” on page 31. The AT-FS708LE switch is now ready for use.
30 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.
AT-FS708LE Instal lation Guide 31 Warranty Registration When you finish insta lling the product, you should register you prod uct by completing the enclosed warranty card and sending it in.
32 ❑ Verify that the node connected to the port on the switch is powe red ON. If the node is OFF, power the un it ON. ❑ Verify that the di stance between the switch and the connected network device is no greater than 100 meters (328 feet).
