Adding or Replacing the Optional Fast Ethernet ModuleFast Network 10 User GuidePage 2-92.4.1 Connecting the AUI InterfaceThe FN10 includes one Ethernet Attachment Unit Interface (AUI)connector (Port 1). To connect the AUI to a thick coax network, you mustuse an AUI drop cable and a tap-type transceiver:1. Attach a tap-type transceiver to the thick coax cable. Refer to thetransceiver manufacturer’s documentation for installationinstructions.2. Connect one end of the AUI drop cable to the FN10’s AUI port and theother end to the tap-type transceiver.To connect the AUI to an alternate media, such as thin coax, you must usea transceiver connected to the AUI port. Be sure that the transceivermatches the type of Ethernet cable you are using.2.5 ADDING OR REPLACING THE OPTIONAL FASTETHERNET MODULEThe FN10 is available with an optional Fast Ethernet module to add twoadditional ports that can be configured for either 10 or 100 Mbps. If youhave purchased a FN10/FE, the Fast Ethernet (FE) module is alreadyinstalled in your FN10.If you have purchased the FE module separately, or you need to replace anexisting FE module, follow the steps below:1. Disconnect the FN10 from the network and remove the power cordfrom the rear.2. Loosen the 2 spring-loaded fastening screws securing the blankbackplate and remove the backplate from the FN10. Refer toFigure 2-5.NOTEThe Ethernet Attachment Unit Interface (AUI) Port and Port 1on the FN10’s front panel cannot be used simultaneously. Ifyou connect an RJ45 cable to Port 1 and an AUI cable to theAUI Port, the FN10 automatically uses the RJ45 connection, aslong as there is a good link. If there is no link on Port 1, or thelink goes down, the FN10 automatically switches to the AUIPort until there is a good link on Port 1.
