3Com 3C12066 Installation And Use

Coaxial Transceiver Module 3C12066 1 Interworking Information The 3Com® LinkBuilder® Coaxial Transceiver Module has been designed to the IEEE 802.3 specification. The Transceiver Module can transmit and receive Ethernet 10 Mbit/sec traffic over thin Ethernet cable. The Transceiver Module features switchable internal/external coaxial termination, Jabber protection and selectable SQE Test. The Transceiver Module is used to provide an extra port or connectivity to thin Ethernet on the following LinkBuilder products: • ECS modules (3C12076, 3C12050/1) • MSH modules (3C18110, 3C18120, 3C18124 and 3C18146) • FMS Stackable Hubs (3C16250, 3C16265, 3C16271 and 3C16371) • FMS II Stackable Hubs (3C16670 and 3C16671) Repeaters (3C16170, 3C16200, 3C16210 and 3C16505) This product has the benefit of a "lifetime warranty", details of which are given on page 4 of this manual. 2 Setting up the Module Segment Termination The thin Ethernet cable may be connected to the Transceiver Module in one of two ways – externally terminated or internally terminated. External termination uses a T-piece adapter, with terminator fitted, between the cable and the module. An in-line terminated adapter may be used if you prefer. Move SWITCH 1 (Figure 2) to the ‘EXT’ position. With internal termination, the cable is connected directly to the BNC socket, and the termination selector (SWITCH 1 in Figure 2) moved to the ‘INT’ position. Access to the slide switch is through a slot in the metal mounting panel of the Transceiver Module, where the positions are labelled. The modules are shipped with SWITCH 1 set for internal termination. Ensure that SWITCH 1 is selecting the termination mode you require.

enabled or disabled depending on the application. The function must be disabled for operation when installed in a Repeater. The function should be enabled for operation when connected to a LinkBuilder ECS Local Bridge Module 3C12050/1. SQE Test is disabled when the jumper plug of LINK1 (Figure 1) occupies the DIS position. The Transceiver Module is supplied with SQE Test disabled. Check that LINK1 is in the required position, and move if necessary. 3 Installation Only qualified personnel should install this device. Observe normal anti-static precautions! Use an earthed wrist-band! A 16-pin header and a 16-way edge connector are mounted on the Transceiver Module for connection to a Module, Stackable Hub or Repeater. Connection of the Transceiver Module to a thin Ethernet segment is through the BNC connector on the front panel of the Transceiver Module. Before you install the Transceiver Module, you must remove the mother device 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 ‘How to Install and Use...’ manual. Remove the blanking plate from the unit in which you are going to install the Transceiver Module. The relevant manual will tell you where to find the plate. Keep the blanking plate in a safe place so that it can be replaced if the Transceiver Module is removed in future. Installing on 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. Hold the Transceiver Module by the mounting panel and board edge with the header pins facing down. Pass the board of the Transceiver Module through the cut-out in the front panel. Align the socket on the card with the pins on the Transceiver Module and push down firmly to connect. With the 3C18146 Expansion Module, you align the header and pins and press gently to engage the pins. Turn the pair over to rest on the Transceiver Module and press firmly close to the header to complete connection. Fix the mounting panel of the Transceiver Module to the module using the two screws from the blanking plate. Connection Before proceeding with the installation of the module, check that the host equipment is set up to take the module. See the relevant ‘How to Install and Use...’ manual. Re-install the mother device into its chassis and/or network. Connect the Transceiver Module to the thin Ethernet segment using the chosen method. If you change your mind about the method of termination, you may reset the switch to the appropriate position without removing power from the Transceiver Module. 4 Operation The Transceiver Module will operate correctly once power is applied to its host equipment. 5 Problems If, after installing the Transceiver Module, no communication is possible, check the settings of the host unit and that it is receiving power. Also, check the positions of the switch and link on the module. Ensure correct terminations are present. If no error is found, refer to the supplier of your 3Com Coaxial Transceiver Module for further advice.
