Preparing for Installation
If you are installing the Transceiver
Module in a:
■
Hub or repeater – Remove the device
from the network and all power
sources.
■
Module – Remove the module from all
power sources and the chassis (you do
not need to power off the chassis).
■
3C18146 Expansion Module – Separate
the Expansion Module from its mother
module.
Refer to the relevant user guide or How to
Install and Use... manual for instructions.
Remove the blanking plate from the
module, hub, or repeater which is to
receive the Transceiver Module. Refer to
the relevant manual for the plate location.
Keep the blanking plate in a safe place so
it can be replaced if the Transceiver
Module is removed.
Installing in a Stackable Hub or
Repeater
If you are installing the Transceiver
Module in a:
■
FMS stackable or repeater – Hold the
mounting panel with the pin header
side of the board
down
.
■
SuperStack II stackable – Hold the
mounting panel with the pin header
side of the board
up
.
1
Insert the edge connector end of the
Transceiver Module into the rear of the
mother device. Carefully slide the
Transceiver Module into the slot and
push it all the way in.
2
Using the two screws from the blanking
plate, attach the mounting panel of the
Transceiver Module to the back panel.
3
Return power to the unit.
Installing on an ECS or MSH Module
1
Position the ECS or MSH Module on a
flat surface with the 16-way socket
facing up.
2
Hold the Transceiver Module by the
mounting panel and board edge with
the header pins facing down.
3
Pass the board of the Transceiver
Module through the cut-out in the front
panel.
4
Align the socket on the ECS or MSH
Module with the pins on the
Transceiver Module and push down
firmly to connect.
Note:
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 the
connection.
5
Using the two screws from the blanking
plate, attach the mounting panel of the
Transceiver Module to the module.
6
Re-install the mother device into its
chassis and network and power on.
Connecting the Module
After the Transceiver Module is installed:
1
Connect two fiber optic cables to the
Transceiver Tx and Rx connectors.
2
Align the keyways with the bayonets.
3
Push and twist until locked.
CAUTION:
Keep the ends of the
connectors clean. Wipe with a
tissue moistened with ethanol if
necessary.
Ensure the other end of the fiber cables
are connected to the opposite ports (Rx
to Tx and Tx to Rx if the cables are
marked) of a remote 10BASE-FB device.
If the cables are not marked, 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 Link LED lights solid green. If the
LED is blinking, change the fiber cables
over to the opposite ports.
The Link LED on the Transceiver Module
should now light solid green.
Troubleshooting
If the LED is blinking, refer to the section
LED Indications on page 1 to define the
error condition and check the following:
■
Fiber cable connections (Tx to Rx /Rx
to Tx)
■
Continuity of the fiber cable
■
Cleanliness of the connectors
■
Power status of the remote unit
(should be powered on)
If the Transceiver Module powers on but
no communication is possible, contact
your Transceiver Module supplier.
Ensuring Optical Safety
Although the LEDs and Lasers used in this
