SUPERSTACK® II SWITCH GIGABIT ETHERNET SX
MODULE USER GUIDE
Rear view of a SuperStack II Switch with the Gigabit Ethernet SX Module installed
The Gigabit Ethernet SX Module (3C16925)
The Gigabit Ethernet SX Module provides a 1000Mbps
Gigabit Ethernet fiber port for the following units:
SuperStack II Switch 1000, SuperStack II Desktop Switch,
SuperStack II Switch 3000, LinkSwitch 1000 and
LinkSwitch 3000. This port can be used to connect the
Switch to the backbone of your network — for example,
to a Gigabit switch such as the SuperStack II Switch 9000
SX — or, to a server or endstation with a Gigabit Ethernet
connection.
The Module requires agent software version 3.21 or later
to be installed on the Switch. For instructions on upgrading agent software, refer to the User Guide supplied with
your Switch.
Gigabit Ethernet offers a scalable, end-to-end solution
that delivers the highest performance available while
maintaining compatibility with existing Ethernet and Fast
Ethernet networks. The Module conforms to IEEE 802.3z
Draft 3.1 for Gigabit Ethernet, with the exception that
only full duplex is supported. The port uses 850nm multimode fiber cable with SC connectors, and supports a segment length of 260m (853ft).
LEDs
LEDs on the front of the Switch show the status of the
Module and its packet activity. The Module itself also has
LEDs, as shown in Figure 1.

Installation and Removal
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: Fiber Optic ports — Optical Safety
WARNHINWEIS: Faseroptikanschlüsse — Optische
Sicherheit
Niemals direkt auf den Faser-TX-laser-Anschluß und auf
die Faserkabelenden schauen, während diese eingeschaltet
sind.
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 Modules in appropriate
anti-static packaging.
Installing the Module into a Switch
Never look directly at the fiber TX laser port and fiber
cable ends when they are powered-up.
AVERTISSEMENT: Ports pour fibres optiques — sécurité
sur le plan optique
Ne regardez jamais directement le port TX laser à fibres
optiques et les embouts de câbles à fibres optiques tant
qu'ils sont sous tension.
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 small
cross-bladed 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 connectors are fully engaged. Tighten the two captive thumbscrews securing the Module.
When using the Module with version 3.21, note the following:
5 Connect the Module:
a Remove the protective plastic covers from the fiber
connections on the Module.
b Ensure that the Switch is powered-up.
c Plug the SC connector on the fiber cable into the fiber
socket on the Module.
d Connect the other end of the fiber optic segment to a
device fitted with a Gigabit Ethernet connection.
6 Check the LEDs on the front of the Switch to ensure that
the Module is operating correctly. Refer to “LEDs” for
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 Place the Switch on a flat surface. Undo the two captive
thumbscrews securing the Module into the Switch. Do not
remove any other screws from the rear of the Switch.
3 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 and to aid the circulation
of cooling air.
About the Switch Agent Software
Agent software version 3.21 provides support for:
The Gigabit Ethernet SX Module
All the functionality available in version 3.1.
The default Spanning Tree Protocol (STP) path cost for
the Module port is 60.
The Module supports the flow control system as
defined by IEEE 802.3z Draft 3.1 (Intelligent Flow
Management is not supported).
The Module port cannot be a Virtual LAN Trunk (VLT)
port.
Agent software cannot be upgraded over the Module
port.
The Interactive Access feature of PACE is not supported
by the Module port.
Token Ring Encapsulation is not supported by the
Module port.
For further details about version 3.21, see the README
file on the agent software disks supplied with the Module.
Problem Solving
If you suspect a problem, carry out these steps before
contacting your supplier:
Ensure that the Switch in which the Module is fitted is
powered-up.
Ensure that the Module is correctly installed.
Ensure that the device at the far end of the link is
powered-up and operating correctly.
Reverse the Tx and Rx connections.
Check that all connectors on the fiber optic segment
are all correctly engaged.
Clean the terminators by wiping them gently with a
clean tissue or cotton bud moistened with ethanol.
Dirty fiber terminators on the fiber optic segment
impair the quality of the light transmitted through the
cable.
