[. . . ] 3 Installation 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. A 16-pin header and a 16-way edge connector are mounted on the Transceiver Module for connection to a Module, a Stackable Hub or a Repeater. The Rx and Tx fiber optic cables, terminated with ST (bayonet type) connectors, attach to the Fiber Optic connectors on the front panel of the Transceiver Module. The LED labelled "Rx loss" is lit when the optical signal is not present on the Rx fiber cable. ! Page 4 Page1 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). 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 module, hub or repeater which is to receive 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 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. 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. Page 2 Align the socket on the Module 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.

The other end of the fiber cables should be connected to the opposite ports (i. e. Rx to Tx and Tx to Rx if the cables are marked) of a remote FOIRL device. If the cables are not marked, just connect them to a port pair. With power supplied to the devices, verify that the cables are connected to the correct port by checking that the `Rxloss' LED of the Transceiver Module is not lit. [. . . ]
