Chapter 1 Overview The AT-FS238a/x and AT-FS238b/x Series Bridging Converters are the 10/100Mbps fast switch single-mode fiber transceivers which can send and receive on two different wavelengths (1310nm and 1550nm) on a single-mode fiber cable.
Overview The fiber optic port operates at 100 Mbps, while the twisted pair port operates at 10 Mbps or 100 Mbps. Both ports feature half- and full-duplex operation. AT-FS238a/x and AT-FS238b/x Series Bridging Converters can be installed on a desktop or in an AT-MCR12 chassis. These bridging converters are easy to install and do not require software configuration or management.
AT-FS238a/x and AT-FS238b/x Series Installation Guide The back panel of the AT-FS238a/x and AT-FS238b/x Series Bridging Converters features a receptacle power connector and DIP switches for manually configuring the ports. Note The AT-FS238a/x and AT-FS238b/x Bridging Converters are designed with 2 different receptacle connectors: 12VDC only or 12-50VDC version models.
Overview Table 1 lists the maximum operating distances for the bridging converters.

Overview Status LEDs Table 2 defines the LEDs for the bridging converters. Table 2 Status LEDs LED Color Description PWR Green Power is applied to the unit. AUTO NEG Green Auto-negotiation on the twisted pair port is enabled. OFF Auto-negotiation on the twisted pair port is disabled. Green The twisted pair port is operating at 100 Mbps. OFF The twisted pair port is operating at 10 Mbps. Green A valid link has been established on the port.
AT-FS238a/x and AT-FS238b/x Series Installation Guide Twisted Pair Port The AT-FS238a/x and AT-FS238b/x Series Bridging Converters 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 100Base-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.
Overview 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 bridging converter 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-FS238a/x and AT-FS238b/x Series Installation Guide Duplex Mode The fiber optic port on the bridging converter can operate in half- or fullduplex mode. You must set the duplex mode manually using the DIP switches on the back of the unit. Mode Selection Button Link Test The link test is a fast and easy way for you to test the connections between the bridging converter ports and the end-nodes that are connected to the ports.
Overview Note MissingLink or Smart MissingLink is disabled when you perform a link test. Consequently, to ensure that the MissingLink or Smart MissingLink is enabled on the bridging converter, always set the Mode Selection button so that the ML or SML LED is green during normal network operations. Smart MissingLink Like MissingLink, the Smart MissingLink feature terminates the link on the failed port thereby notifying you when a connection has been lost.
AT-FS238a/x and AT-FS238b/x Series Installation Guide DIP Switches The DIP switches are used to manually configure the operating characteristics of the ports. These characteristics include the port speed, duplex mode, and auto-negotiation. On the 100Base-FX fiber optic port, you can manually set the duplex mode to either half- or full-duplex.
Overview The bridging converter will discard CRC errors, misaligned, runt, and underoversized packets. When the packet has dribble bits at the end, the bridging converter will truncate to octet boundary and check for a good FCS before forwarding. Network Topologies Figure 6 illustrates a back-to-back topology using one AT-FS238a/x and one AT-FS238b/x Series Bridging Converters to interconnect two small networks of stackable hubs.
