1 Chapter 1 Description The AT-FS20x and AT-FS202SC/FSx Seri es Switches include the following models: The AT-FS20x Series switches are design ed to extend the distance of your network by converti ng Fast Ethernet data between twisted-pair ca bling and either multimode or single -mode fiber optic cabling.
Description 2 Figure 1 illustrates the front panel of an AT-FS20x Series switch. Figure 1 AT-FS20x Series Front Panel (AT-FS202 Model) Figure 2 illustrates a front panel of an AT-FS202SC/FSx Series switch.
AT-FS20x Series Installation Guide 3 Table 1 lists the maximum operating distances for the switches. Table 1 Maximum Operating Distances Model 100Base-FX 10/100B ase-TX Connector Maximum Operating Distance 1 1.
Description 4 Key Features The AT-FS20x switches have the following features: ❑ LEDs for unit a nd port statu s ❑ Auto MDI/MDI-X ❑ DIP switches for configuring the ports ❑ Half- or full-duplex.
AT-FS20x Series Installation Guide 5 Twisted-Pair Port The AT-FS20x and AT-FS202SC/FSx Se ries switches have one 10Base-T/ 100Base-TX twisted-pair port. The twis ted-pair port features an RJ-45 connector. Port Speed The twisted-pair port is compliant with the 10Base-T and 10Base-TX standards and is capable of either 10 Mb ps or 100 Mbps operat ion.
Description 6 The twisted-pair port on the switch can operated in either half- or full-duplex mode. You can set the duplex mode manu ally or allow the switch to set it automatically through Auto-Negotiation . With Auto-Negot ia tion, if the end- node is capable of full-duplex mode, the twisted-pair port is set automatically to full-duplex mode.
AT-FS20x Series Installation Guide 7 Switch Performance The AT-FS20x switches have th e following performance values: ❑ 148,800 pps for 100 Mbps and 14,880 pps for 10 Mbps for full wire speed forwar.
Description 8 Store and Forward The AT-FS20x switches suppo rt store and fo rward switching at Fast Ethern et full-wire speed in 100 Mbps, half- or fu ll-duplex mode. Pack ets entering each port are stored in buffers. Once the pack et is received, the switch forwards or discards the packet, depe nding on its destination address and error status.

Installing the Switch 14 ❑ Refer to Table 5 for the cabling specificatio ns for the fiber optic port operating in half-duplex mode. Table 5 100Base-FX Fiber Optic Ports (Half-duplex) 1 1. The total dista nce of the fib er optic lengths can not exceed the limi ts stated in the table.
AT-FS20x Series Installation Guide 15 Installing the Switch This section provides a procedure for installing the AT-FS2 0x switches. When setting the DIP switches consider the following: ❑ Setting the Aut o Neg DIP switch for the twi sted-pair port to ON or OFF enables or disables auto-negotia tion for the port.
Installing the Switch 16 Caution After you change the speed or duplex mode of the switch, you must power cycle (shut down and restart) the sw itch for the new settings to take affect. 4. Place the switch on a secure, level surface, leaving ample space around the switch for ventilation.
AT-FS20x Series Installation Guide 17 10. Connect the twisted-pair cabl e (or cables) to the end node. See Table 7 for information about setting the duplex mode. You must set the AT-FS20x switch and the end node to auto negotiate or make their port speeds match.

19 Chapter 3 Troubleshooting Follow the guidelines below to test and troubleshoot the in stallation in the event a problem occurs. Note Whenever the speed and/or duplex mode are changed during or after power ON, power OFF then power bac k ON the switch to load the new configuration.
Troubleshooting 20 ❑ Make sure that the twisted-pair ca ble does not exceed 100 meters ( 328 feet) and that you are using a Catego ry 3 or better cable for 10Base-T operation or a Category 5 or better cable for 100Base-TX operation. For information about maximum operating distances, see Table 1 on page 3 .
