AT-FS20x and AT-FS202SC/FSx Series Installation Guide Twisted Pair Port The AT-FS20x and AT-FS202SC/FSx Series Switches have one 10Base-T/ 100Base-TX twisted pair port. The twisted pair port features a 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 Mbps or 100 Mbps operation. You can set the port speed manually or, since the port is IEEE 802.
Description Auto MDI/MDI-X An RJ-45 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. The RJ-45 port on a PC, router, or bridge is typically wired as MDI, while the 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 MDI to MDI-X, you would usually use a straight-through twisted pair cable.
AT-FS20x and AT-FS202SC/FSx Series Installation Guide Switch Performance The switches perform at: ❑ 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 kib bytes (per port) packet buffer ❑ Low latency 15.
Description Store and Forward The AT-FS20x and AT-FS202SC/FSx Series Switches support store and forward switching at Fast Ethernet full-wire speed in 100 Mbps, half- or fullduplex mode. 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.
AT-FS20x and AT-FS202SC/FSx Series Installation Guide Network Topologies Figure 4 illustrates a topology using one AT-FS201 switch to interconnect two small networks of stackable hubs. Network 1 has an AT-FH812u with an AT-FH807u switching module connected to the 100Base-FX port on the AT-FS201. Network 2 has an AT-3624TR hub connected to the 10Base-T/ 100Base-TX port on the AT-FS201.
Chapter 2 Installing the Switch This chapter explains how to install an AT-FS20x or AT-FS202SC/FSx Series Switch. These switches can be installed on a desktop or in an AT-MCR12 chassis. Verifying Package Contents Make sure the following items are included in your package. If any item is missing or damaged, contact your Allied Telesyn sales representative for assistance.
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.
AT-FS20x and AT-FS202SC/FSx Series Installation Guide ❑ Refer to Table 4 for the cabling specifications for the fiber optic port operating in full-duplex mode.

Installing the Switch ❑ Refer to Table 5 for the cabling specifications for the fiber optic port operating in half-duplex mode.
AT-FS20x and AT-FS202SC/FSx Series Installation Guide Installing the Switch To install an AT-FS20x or AT-FS202SC/FSx Series Switches, perform the following procedures: 1. Remove all equipment from the package and store the packaging material in a safe place. Note Do not remove the dust cover from the fiber optic port until you are ready to connect the fiber optic cable. Dust contamination can adversely impact the operating performance of the port and the switch. 2.
Installing the Switch 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. ❑ For the fiber optic port, set the port’s duplex mode using the appropriate Duplex Mode DIP switch.
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.
Troubleshooting 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. ❑ Check that the fiber optic cable is securely connected to the fiber optic port on the switch and on the end-node. ❑ Check to be sure that the end-node connected to the port is operating at 100 Mbps. ❑ Check to be sure that the end-nodes connected to the switch are operating at the same duplex mode.
