TP
Transceiver Interface Module has been
designed to the IEEE 802.3 10BaseT
specification.
The Transceiver Module can transmit
and receive Ethernet 10 Mbit/sec
traffic over Shielded or Unshielded
Twisted Pair cable. The Transceiver
Module features crossover
(MDI/MDIX) switching, SQE Test
selection and link monitoring using the
Link LED (Light Emitting Diode).
The Transceiver Module is used to
provide connectivity to twisted pair
cable 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, 3C16671 and 3C16672)
LinkBuilder TP/12 (3C16170) and
LinkBuilder TP/8i (3C16181) hubs
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
MDI/MDIX
The PL2 component switches the TP
port between MDI and MDIX.
MDI is the default setting and allows
the Transceiver Module to be
connected by normal twisted pair
cable to an MDIX port on another hub
to form an inter-repeater link.
If MDIX is selected the Transceiver
Module can be connected to a
workstation or any other Data
Terminal Equipment. It can also be
connected to another hub which is
already set to MDI to form an
inter-repeater link.
See Figure 1 to locate the MDI/MDIX
jumper and then Figure 2 to ensure
you have the correct selection.
This manual details the installation and use of the 3Com TP Transceiver Interface Module,
3C12063. Please retain this manual with your other 3Com manuals for future use.

SQE Test
The PL1 component allows you to
enable or disable the SQE Test. The
SQE Test is used by 802.3 transceivers
to confirm that the transceiver is
functioning correctly. 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.
The Transceiver Module is supplied
with SQE Test disabled.
See Figure 1 to locate the SQE Test
jumper and then Figure 3 to ensure
you have the correct selection.
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.
A Twisted Pair cable can be connected
to the RJ45 connector on the front of
the Transceiver Module.
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.
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. See Figure 1 to
locate the pin header.
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 in an ECS or MSH 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.
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. See
Figure 1 to locate the header pins. 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
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
TP segment.
4 Operation
Link LED
The Link LED on the front of the
Transceiver Module lights green when
a link is detected. If a link is not
present the LED does not light.
5 Problems
If the Link LED does not light when
the Transceiver Module is installed the
cause may be one of the following:
Both ends of the link are configured as
MDI - change one to MDIX.
Both ends of the link are configured as
MDIX - change one to MDI.
The far end device is not powered up
or may be faulty. Check the device.
The cable linking the devices is broken
or incorrectly wired. Change the cable.
