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. 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.
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.
Connection
Once the Transceiver Module is
secured in place, attach an external
transceiver, directly or with an AUI
cable. Remember to engage the
slidelocks at both ends of the AUI
cable, if you use one.
3
Operation
Re-install the mother device into its
chassis and/or network and power up.
The Transceiver Module will operate
correctly once power is applied.
4
Problems
If, after installing the Transceiver
Module, no communication is possible,
check the settings of the host unit and
that it is receiving power. If no error is
found, refer to the supplier of your
3Com Female AUI Transceiver Module
for further advice.
