1 6 RJ-45 10/100/1000 Ports
WARNING
: RJ-45 ports. These are shielded RJ-45 data
sockets. They cannot be used as telephone sockets. Only
connect RJ-45 data connectors to these sockets. Either
shielded or unshielded data cables with shielded or
unshielded jacks can be connected to these data
sockets.
AVERTISSEMENT: Les ports RJ-45. Il s'agit de prises
femelles blindées de données RJ-45. Vous ne pouvez pas
les utiliser comme prise de téléphone. Branchez
uniquement des connecteurs de données RJ-45 sur ces
prises femelles. Les câbles de données blindés ou non
blindés, avec les jacks blindés ou non blindés, l'un ou
l'autre, peuvent être branchés à ces prises de courant de
données.
WARNUNG: RJ-45-Anschlüsse. Dies sind abgeschirmte
RJ-45-Datenbuchsen. Sie können nicht als Telefon-
anschlußbuchsen verwendet werden. An diesen Buchsen
dürfen nur RJ-45-Datenstecker angeschlossen werden.
Diese Datenstecker können entweder mit abgeschirmten
oder unabgeschirmten Datenkabeln mit abgeschirmten
oder unabgeschirmten Klinkensteckern verbunden
werden.
The Baseline 10/100/1000 Switch 6-Port has 6
10/100/1000 Mbps auto-negotiating ports. Each port
automatically determines the correct speed and duplex
mode as one of the following:
T 10BASE-T half duplex
T 10BASE-T full duplex
T 100BASE-TX half duplex
T 100BASE-TX full duplex
T 1000BASE-T full duplex
CAUTION: The Baseline 10/100/1000 Switch 6-Port
supports full duplex auto-negotiation. If the connected
!
device does not support auto-negotiation, the Switch will
operate in half duplex mode (even if the device is

operating in full duplex mode). In such a configuration,
you may notice some degradation of network
performance. 3Com recommends that you use devices
that are capable of auto-negotiation (and that you ensure
that auto-negotiation is enabled, if it is a configurable
option).
All ports auto-sense an MDI/MDIX connection and can
be used to connect to either another switch port, server,
or workstation without additional configuration. Each
port can be connected to a device with a normal
'straight through' TP (twisted pair) cable or a 'cross-over'
TP cable.
2 Activity Status LEDs
The top row of Status LEDs, labelled "Activity", show
the activity of the related ports:

No packet(s) received or transmitted on this port.
3 Link/Duplex Status LEDs
The second, third, and fourth row of Status LEDs,
labelled "10", "100", "1000", show the link or speed
