NTRODUCTION

The SuperStack II Switch 1000BASE-T Module provides a
Gigabit Ethernet module for the SuperStack II Switch
1100 (12 and 24 port), SuperStack II Switch 3300 (12
and 24 port), and SuperStack II Switch 3300 FX.

The module requires management software version 2.42
or later to be installed on the Switch. For instructions on
upgrading management software, refer to the
documentation supplied with your Switch.

The module conforms to the full duplex implementation
of the Gigabit Ethernet standard IEEE 802.3ab. The
module supports a 100 m cable segment, using
Category 5 copper cabling and RJ-45 connectors, as
defined in the ANSI/TIA/EIA-568-A Commercial Building
Telecommunications Cabling Standard, and in the
1000BASE-T standard.

A white paper which describes 1000BASE-T technology
and cabling requirements in more detail is available from
the 3Com

NSTALLATION AND

R

EMOVAL

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: RJ-45 Port. This is a shielded RJ-45 data
socket. It cannot be used as a telephone socket. Only
connect RJ-45 data connectors to this socket.

Either shielded or unshielded data cables with shielded or
unshielded jacks can be connected to this data socket.

AVERTISSEMENT: Le port RJ-45. Il s'agit d’une prise
femelle blindée de données RJ-45. Vous ne pouvez pas
l’utiliser comme prise de téléphone. Branchez uniquement
des connecteurs de données RJ-45 sur cette prise femelle.

Les câbles de données blindés ou non blindés, avec les jacks
blindés ou non blindés, l'un ou l'autre, peuvent être
branchés à cette prise de courant de données.

WARNHINWEIS: RJ-45 Ports. RJ-45-Anschluß. Dies ist
eine abgeschirmte RJ-45-Datenbuchsen. Sie kann nicht als
Telefonanschlußbuchsen verwendet werden. An diesen
Buchsen dürfen nur RJ-45-Datenstecker angeschlossen
werden.

Dieser Datenstecker kann entweder mit abgeschirmten
oder unabgeschirmten Datenkabeln mit abgeschirmten
oder unabgeschirmten Klinkensteckern verbunden werden.

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 anti-static
packaging.

Installing the Module into a Switch

CAUTION: When a module is installed into a Switch, the
Switch can only support one port trunk, instead of two.
If you have two port trunks configured on your Switch,
remove the second one before installing the module. If
you do not remove the second port trunk, both port
trunks are automatically removed.

CAUTION: If the module replaces a 1000BASE-SX or a
1000BASE-LX module, all user settings are retained, with
the exception of auto-negotiation, which is always
enabled. If the 1000BASE-T module replaces any other
type of module, all user settings return to their default
values.

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
connectors are fully engaged. Tighten the two captive
thumbscrews securing the module.

5 Install the module:

a Ensure that the Switch is turned on.
b Plug the RJ-45 connector on the cable into the RJ-45

socket on the module.

c Connect the other end of the cable segment to a

device fitted with a 1000BASE-T Gigabit Ethernet
connection.

6 Check the LEDs on the front of the Switch to ensure

that the module is operating correctly. Refer to “LEDs”
on page 1 for more information.

Removing the Module from a Switch

1 Ensure that the power supply and 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 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.

ODULE

The module requires management software version

2.42 or later to be installed on the Switch. For
instructions on upgrading management software, refer
to the documentation supplied with your Switch.

Support for the management software is supplied by
3Com Transcend

When the module is installed in a suitable Switch, the
Switch interfaces contain features to monitor the
auto-negotiation system specified in the IEEE 802.3
Ethernet standard. This system allows the module port
to automatically detect the flow control setting of a
Gigabit Ethernet link.

M

When using the module port, note the following:



The port only operates in full duplex.



The port only supports full duplex flow control in
symmetrical mode, as defined by the Gigabit
Ethernet standard. You cannot disable or alter this
mode.



The port only supports the Store and Forward
forwarding mode.



The port does not support PACE.



You cannot manage the port using the Internetwork
Packet Exchange protocol (IPX).

Ensure that the Switch in which the module is fitted
is turned on.



Ensure that the module is correctly installed in the
Switch.



Ensure that the device at the far end of the link is
on and operating correctly.
