NTRODUCTION
This guide covers the following products:
SuperStack® 3 Switch 4300 100BASE-FX Module
(3C17111) provides one Fast Ethernet fiber optic port
for connection to your network.
SuperStack 3 Switch 4300 100BASE-FX Dual Module
(3C17112) provides two Fast Ethernet fiber optic ports
for connection to your network.
The procedures described in this User Guide assume that
you have a single port Module. If you have a Dual
Module the procedures are the same, except that
procedures relating to the port apply to each port on the
Dual Module.
The Module conforms to the half and full duplex
implementation of the Fast Ethernet standard, IEEE
802.3u, and the port provides a 100 Mbps connection to
another 100BASE-FX device. The port can operate in
either half or full duplex mode and uses 62.5 µm
multimode fiber optic cable with MT-RJ duplex
connectors. The port supports the segment length
specified in IEEE 802.3u, as shown below:
Fiber Size Fiber Bandwidth Segment Lengths Supported
62.5 µm 500 MHz*km Half Duplex: 2–412 m (7–1487 ft)
Full Duplex: 2–2000 m (7–7220 ft)

AFETY INFORMATION
WARNING: Installation and removal of the Module must
be carried out by qualified personnel only. Before
installing the Module into a unit, you must first
disconnect the unit from the mains power supply. For full
safety instructions, refer to the user guide that
accompanies the unit.
AVERTISSEMENT: Confiez l'installation et la dépose de
ce Module à un personnel qualifié. Avant d'installer ce
Module dans un groupe, vous devez au préalable
débrancher ce groupe de l'alimentation secteur. Pour
prendre connaissance des consignes complètes de
sécurité, consultez le guide utilisateur qui accompagne ce
groupe.
WARNHINWEIS: Die Installation und der Ausbau des
Moduls darf nur durch Fachpersonal erfolgen. Vor dem
Installieren des Moduls in einem Gerät muß zuerst der
Netzstecker des Geräts abgezogen werden. Vollständige
Sicherheitsanweisungen sind dem Benutzerhandbuch des
Geräts zu entnehmen.
WARNING: When the Module is inserted into the switch,
the captive screws securing the Module must be
tightened with a suitable tool. Keep the blanking plate
and the fixings in a safe place. If you remove the Module
at any time, you must then replace the blanking plate.
AVERTISSEMENT: Quand le Module est inséré dans le
commutateur, visser le module, en le securisant fortemant
avec un outil adapté. Conservez la plaque d'obturation et
les fixations en lieu sûr. Si vous retirez le Module à tout
instant, vous devez alors replacer la plaque d'obturation.
WARNING: Optical Safety
Under normal viewing conditions, there is no eye hazard
from the transmit LED. We recommend, however, that you
do not view the LED through any magnifying device while it
is powered on. Never view the fiber Tx port or fiber cable
ends directly when the Module is powered on.
AVERTISSEMENT: Sécurité sur le plan optique
Sous les conditions de visionnement ordinaires, il n'y a
pas de danger à l'oeil à cause de la diode
électroluminescente d'émission. C'est recommandé,
cependant, que la diode électroluminescente ne soit pas
examinée avec aucun appareil de grossissement pendant
qu'elle est sous tension. C'est recommandé que le port
de fibre Tx et les fins de câble du fibre ne soient jamais
directement examinées pendant qu'ils soient sous tension.
WARNHINWEIS: Optische Sicherheit
WARNHINWEIS: Beim Einsetzen des Moduls in dem
Switch sind die unverlierbaren Schrauben mit einem
passenden Werkzeug festzuziehen. Die Distanzplatte und
die Befestigungselemente an einem sicheren Ort
aufbewahren. Beim Austausch des Moduls ist auch die
Distanzplatte zu ersetzen.
Unter normalen Umständen geht von der übertragenden
LED keine Gefahr für die Augen aus. Es wird aber
empfohlen, die LED nicht durch Vergrößerungslinsen zu
betrachten solange die Leuchtdiode unter Strom steht.
Ebenso ist es ratsam den Glasfaser Tx Anschluß und die
Enden der Glasfaserkabel nicht direkt zu betrachten
solange diese unter Strom stehen.

Handling the Module
The Module can be easily damaged by electrostatic
discharge. To prevent damage, observe the following:
Always wear an anti-static wristband connected to a
suitable earth point.
Do not remove the Module from its packaging until
you are ready to install it into a Switch.
Do not touch any of the pins, connections or
components on the Module.
Handle the Module only by its edges and front panel.
Always store or transport the Module in anti-static
packaging.
Installing the Module into a Switch
CAUTION: This Module is not hot-swappable. Always
make sure that the Switch is powered down and
disconnected from the mains before installing or
removing a Module. Use the following instructions when
installing or removing a Module.
Each Switch has the facility to accept up to two
Expansion Modules, allowing Gigabit Ethernet or Fast
Ethernet connections. Modules can be inserted into either
Expansion Module slot.
Figure 1
Inserting the Module into the Switch
Keep the blanking plate in a safe place. If you remove the
Module at any time, you must replace the blanking plate
to prevent dust and debris entering the Switch. Replacing
the blanking plate will also help circulate cooling air
through the Switch.
Activating the Module
1
Ensure that the Switch is powered-up.
2
Remove the protective stopper from the MT-RJ fiber port
on the Module. Squeeze the top and bottom of the
stopper between your thumb and forefinger then remove
it.
3
Plug the MT-RJ connector on the fiber cable into the
MT-RJ fiber port on the Module.
4
Connect the other end of the fiber optic segment to a
device fitted with a 100BASE-FX connection.
5
Check the LEDs on the front of the Switch to ensure that
the Module is operating correctly. Refer to “
more information.
Removing the Module from a Switch
1
Ensure that the power supply and the fiber backbone
connection cables are disconnected from the Switch.
2
Undo the Module’s two captive screws with a suitable
screwdriver. Do not remove any other screws from the
Switch.
3
Remove the Module.
4
If you are not fitting another Module immediately, you
must replace the blanking plate to ensure that dust and
debris do not enter the Switch. Replacing the blanking
plate will also help circulate cooling air through the
Switch.
