The 3Com® Female AUI Transceiver Module has been designed to the IEEE 802. 3 specification for an AUI interface to provide external transceiver connectivity. The Transceiver Module provides an extra port or connectivity to another medium on the following LinkBuilder® products: · ECS modules (3C12076 and 3C12050/1) · MSH modules (3C18110, 3C18120, 3C18124, 3C18146 and 3C18600) · FMS Stackable Hubs (3C16250, 3C16265, 3C16271 and 3C16371) · FMS II Stackable Hubs (3C16665, 3C16670 and 3C16671) · Repeaters (3C16170, 3C16200, 3C16210 and 3C16505) This product has the benefit of a "lifetime warranty": see page 4. 2 Installation The Transceiver Module provides a 15-pin female AUI connector (acting as a DTE port) at the external interface end. A 16-pin header and a 16-way edge connector are mounted at the other end of the Transceiver Module for connection to a Module, Stackable Hub or Repeater. The Transceiver Module is connected to an external transceiver directly or with an AUI cable (transceiver cable or drop cable) with a maximum length of 50 metres (although in most cases 3 metres should be sufficient). The Transceiver Module will enable the Module, Stackable Hub or Repeater to connect to a variety of transmission medium such as a fiber, UTP, STP or Thin Ethernet. Example Stackable Hub GOVERNING LAW: This Limited Warranty shall be governed by the laws of England. 3Com Limited, ISOLAN House, Brindley Way, London Road, Hemel Hempstead, Hertfordshire, HP3 9XJ, UK. 44(0)442 278000 23/12/93 ! Only qualified personnel should install this device. Use an earthed wrist-band! Female AUI Transceiver Module up to 50 m AUI Cable External Transceiver Thin Ethernet Segment Page 4 Page 1 Preparation Before you install the Transceiver Module, you must remove the Module, Hub or Repeater from the network and all power sources. Modules must be removed from the Chassis (you do not need to power down the Chassis first). The 3C18146 Expansion Module must be separated from its mother module. See the relevant User Guide or `How to Install and Use. . . ' manual. Remove the blanking plate from the unit in which you are going to install the Transceiver Module. Keep the blanking plate in a safe place so that it can be replaced when the Transceiver Module is removed. Installing in a Stackable Hub or Repeater For FMS Stackables and Repeaters, hold the mounting panel with the pin header side of the board down. For FMS II Stackables, hold the mounting panel with the pin header side of the board up. Insert the edge connector end of the Transceiver Module into the rear of the mother device. Slide the Transceiver Module in carefully to engage in the slot and push it fully home. Fix the mounting panel of the Transceiver Module to the back panel using the two screws from the blanking plate. Installing on an ECS or MSH Module Position the Module on a flat surface with the 16-way socket facing up. [. . . ] This digital apparatus does not exceed the Class A limits for radio noise emissions from digital apparatus as set out in the interference-causing equipment standard entitled "Digital Apparatus", ICES-003 of the Department of Communications. Cet appareil numérique respecte les limites de bruits radioélectriques applicables aux appareils numériques de Classe A prescrites dans la norme sur le matériel brouilleur : "Appareils Numériques", NMB-003 édictée par le ministre des Communications. Re-install the mother device into its chassis and/or network and power up. 4 Problems Disclaimer Information in this document is subject to change without notice and does not represent a commitment on the part of 3Com. 3Com reserves the right to revise or change this document without obligation of 3Com to notify any person of the revisions or changes.
