Connecting Workstations and Other
Equipment to Your Hub
WARNING: Please read the ‘Important Safety
Information’ section before you start.
WARNHINWEIS: Bitte lesen Sie den Abschnitt
‘Wichtige Sicherheitsinformationen’ sorgfältig durch,
bevor Sie das Gerät einschalten.
AVERTISSEMENT: Veuillez lire attentivement la
section “Consignes importantes de sécurité” avant de
mettre en route.
CAUTION: Do not power the hub off and on quickly.
Wait about five seconds between power cycles.
Connecting workstations and other equipment to your hub
is easy. Connect them using 100BASE-TX cables to any of
the hub’s 100BASE-TX RJ-45 ports. To connect a
100BASE-TX cable, simply slot the connector into the
relevant RJ-45 port. When the connector is fully in, its latch
locks it into place. To disconnect the cable, push the
connector’s latch in and remove it.
The hub detects all port connections, so you can start using
your network immediately. When you need more ports,
simply add more OfficeConnect hubs.
If you are using the highest-number port (port 4 on
Hub 4, port 8 on Hub 8, port 12 on Hub 12) to
connect a workstation, ensure the Uplink/Normal
switch is set to Normal (out).
Connecting OfficeConnect Hubs Together
You can increase the number of workstations that can
connect to your network by adding another OfficeConnect
hub.
You can directly connect together a maximum of two
Fast Ethernet hubs. The total length of cable (A + B +
C below) between two workstations, or between a
workstation and a non-repeater piece of equipment
(such as a switch), must not exceed 205m (672ft).
Each cable (A, B or C) must not exceed 100m (328ft).
3Com recommends that the cable (B) between the
Fast Ethernet hubs is no longer than 5m (16.4ft). This
allows the maximum hub to workstation cable length
(A or C) of 100m (328ft) to be used, as in Figure 3.
