Description Key Features The AT-FS20x switches have the following features: ❑ LEDs for unit and port status ❑ Auto MDI/MDI-X ❑ DIP switches for configuring the ports ❑ Half- or full-duplex operation on both ports ❑ RJ-45 twisted-pair connector ❑ SC or ST fiber optic connector ❑ Data packet forwarding and filtering at full wire speed (10 Mbps to 100 Mbps, 100 Mbps to 100 Mbps, and 10 Mbps to 10 Mbps) ❑ Store and forward switching mode ❑ Automatic address learning and aging ❑ IEEE 802.
AT-FS20x Series Installation Guide LED Color Description 100M Green The twisted-pair port is operating at 100 Mbps. OFF The twisted-pair port is operating at 10 Mbps. Green The switch is operating in full-duplex mode. OFF The switch is operating in half-duplex mode. Blinking A collision has been detected on the port. Green Auto-Negotiation on the twisted-pair port is enabled. OFF Auto-Negotiation on the twisted-pair port is disabled.
Description The twisted-pair port on the switch can operated in either half- or full-duplex mode. You can set the duplex mode manually or allow the switch to set it automatically through Auto-Negotiation. With Auto-Negotiation, if the endnode is capable of full-duplex mode, the twisted-pair port is set automatically to full-duplex mode. If the end-node is capable of half-duplex mode, the port is set automatically to half-duplex mode.
AT-FS20x Series Installation Guide Switch Performance The AT-FS20x switches have the following performance values: ❑ 148,800 pps for 100 Mbps and 14,880 pps for 10 Mbps for full wire speed forwarding and filtering ❑ 200 Mbps maximum throughput in 100 Mbps, full-duplex mode ❑ 20 Mbps maximum throughput in 10 Mbps, full-duplex mode ❑ Storage for up to 4,000 MAC addresses ❑ 280 kilo bytes (per port) packet buffer ❑ Low latency 15.
Description Store and Forward The AT-FS20x switches support store and forward switching at Fast Ethernet full-wire speed in 100 Mbps, half- or full-duplex mode. Packets entering each port are stored in buffers. Once the packet is received, the switch forwards or discards the packet, depending on its destination address and error status. This ensures that only error-free packets destined for another segment are transferred across the switch, reducing the network load.

Chapter 2 Installing the Switch This chapter explains how to install an AT-FS20x and AT-FS202SC/FSx Series switches. These switches can be installed on a desktop or in an AT-MCR12 chassis. The procedures provided in this chapter are for installation on a desktop. To install a switch in the AT-MCR12 chassis, see the AT-MCR12 Chassis Installation Guide. Verifying Package Contents Make sure the following items are included in your package.
Installing the Switch Planning the Installation Be sure to observe the following guidelines when planning the installation of your switch. ❑ The end-node connected to the 100Base-FX fiber optic port must be able to operate at 100 Mbps. ❑ The end-node connected to the 10Base-T/100Base-TX twisted-pair port can operate at either 10 Mbps or 100 Mbps. ❑ The end-node connected to a port on the switch can be a network adapter card, repeater, router, hub, or another switch.

Installing the Switch ❑ Refer to Table 5 for the cabling specifications for the fiber optic port operating in half-duplex mode.
AT-FS20x Series Installation Guide Installing the Switch This section provides a procedure for installing the AT-FS20x switches. When setting the DIP switches consider the following: ❑ Setting the Auto Neg DIP switch for the twisted-pair port to ON or OFF enables or disables auto-negotiation for the port. If you disable auto-negotiation, be sure to set the DIP switches for the port’s speed and duplex mode to match the speed and duplex mode of the end-node.
Installing the Switch Table 6 DIP Switch Settings (Continued) DIP Switch Number Port Setting Position Description 3 2 Duplex Mode Up The twisted-pair port is operating at half-duplex mode. Down The twisted-pair port is operating at full-duplex mode. 4 2 Auto Neg Up Down Auto-Negotiation on the twisted-pair port is OFF. Auto-Negotiation on the twisted-pair port is ON.
AT-FS20x Series Installation Guide 10. Connect the twisted-pair cable (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.
Installing the Switch 18
Chapter 3 Troubleshooting Follow the guidelines below to test and troubleshoot the installation 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 back ON the switch to load the new configuration. If the PWR LED is OFF, do the following: ❑ If the switch is installed on a desktop, check that the power adapter is securely connected to a power outlet.
Troubleshooting ❑ Make sure that the twisted-pair cable does not exceed 100 meters (328 feet) and that you are using a Category 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. If the LNK/ACT LED for the fiber optic port is OFF, do the following: ❑ Verify that the end-node connected to the port is ON and is operating properly.
