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.
ACHTUNG: 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 three captive thumbscrews 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 introduit dans
le commutateur, il faut visser les trois vis moletées
imperdables, qui bloquent le Module, 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.
ACHTUNG: Beim Einsetzen des Moduls in dem Switch
sind die drei unverlierbaren Flügelschrauben 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.
WARNING: Fiber Optic ports - Optical Safety
Never look at the transmit laser while it is powered-up.
Never look directly at the fiber TX port and fiber cable
ends when they are powered-up.
AVERTISSEMENT: Ports pour fibres optiques – sécurité
sur le plan optique
Ne regardez jamais le laser tant qu'il est sous tension.
Ne regardez jamais directement le port TX (Transmission)
à fibres optiques et les embouts de câbles à fibres
optiques tant qu'ils sont sous tension.
AVERTISSEMENT: L'utilisation de contrôles, de réglages
de performances ou de procédures autres que ceux qui
sont spécifiés au sein du présent document risquent
d'entraîner l'exposition à des rayonnements laser
dangereux.
ACHTUNG: Faseroptikanschlüsse – Optische Sicherheit
Niemals ein Übertragungslaser betrachten, während
dieses eingeschaltet ist. Niemals direkt auf den
Faser-TX-Anschluß und auf die Faserkabelenden schauen,
während diese eingeschaltet sind.
ACHTUNG: Die Verwendung von Steuerelementen
oder die Anpassung von Leistungen und Verfahren in
anderer als der hierin genannten Weise kann zu
gefährlichen Laseremissionen führen.
Handling the Module
The Module can be easily damaged by electrostatic
discharge. To prevent damage, observe the following:
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 wear an anti-static wristband connected to a
suitable earth point.
Always store or transport the Module in anti-static
packaging.
WARNING: Use of controls or adjustments of

Installing the Module into a Switch
CAUTION: This Module is not hot-insertable or
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.
CAUTION: This Module is only designed to work with
the 3Com SuperStack 3 Switch 4900 series.
To install the Module:
1
Ensure that the Switch is disconnected from the mains
power supply and that you are wearing an anti-static
wristband connected to a suitable earth point.
2
Place the Switch on a flat surface. Using a suitable
screwdriver, remove the blanking plate from the rear of
the Switch. Do not remove any other screws from the
rear of the Switch.
3
Keep the blanking plate and screws 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 and to aid the circulation of cooling air.
4
Hold the Module so that the text on the front panel is
upright, and insert it into the Switch, ensuring the back
panel is flush against the back of the Switch. Tighten
the three captive thumbscrews securing the Module with
a suitable tool.
5
To activate the Module:
a
Ensure that the Switch is powered-up.
b
Remove the protective plastic covers from the fiber
connections on the Module.
c
Plug the MT-RJ connector on the fiber cable into the
fiber port on the Module.
d
Connect the other end of the fiber optic cable to a
device fitted with a 1000BASE-SX Gigabit Ethernet
connection.
6
Check the LEDs on the front of the Switch and the rear
of the Module to ensure that the Module is operating
correctly. Refer to “LEDs” below for more information.
