Wall Mounting the OfficeConnect Hub
There are two slots on the underside of the
OfficeConnect hub which are used for wall mounting.
You can mount the hub with the LEDs facing upwards
or downwards. You need two suitable screws. Ensure
that the wall you are going to use is smooth, flat, dry,
and sturdy.
When wall mounting your hub, ensure that it is within
reach of the power outlet.
3
For TP400 or TP800: Make two screw holes 150mm
(5.9in.) apart. Use the guide at the top of page 3 to
mark the position of the holes.
3
For TP1200: Make two screw holes 142mm (5.6in.)
apart. Use the guide at the top of this page to mark the
position of the holes.
Fix the screws into the wall, leaving their heads 3mm
(0.12in.) clear of the wall surface.
Remove any connections to the hub and locate it over
the screw heads. When in line, gently push the hub on
to the wall and move it downwards to secure. When
making connections, be careful not to push the hub up
and off the wall.
CAUTION: Only wall mount single hubs. Do not wall
mount stacked hubs.
Connecting Workstations and Other
Equipment to Your Hub
WARNING: Ensure you have read the Important Safety
Information section carefully before you start.
ACHTUNG: Versichern Sie sich, daß Sie den Abschnitt
mit den wichtigen Sicherheitshinweisen gelesen haben,
bevor Sie das Gerät benutzen.
AVERTISSEMENT: Assurer que vous avez lu
soigneusement la section de L'information de Sécurité
Importante avant que vous commenciez.
CAUTION: Do not power the hub off and on quickly.
Wait about 5 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 RJ45 ports.
100BASE-TX cables are very easy to use. To connect a
100BASE-TX cable, simply slot the connector into the
relevant RJ45 port. When the connector is fully in, its
latch locks it in place. To disconnect the cable, push in
the connector's latch and remove it.
The hub detects all port connections, so you can start
using your network immediately. When you need more
ports, simply add another OfficeConnect hub.
If you are using the highest-number port (port 4 on
TP400, port 8 on TP800, port 12 on TP1200) to
connect a workstation, ensure the MDI/MDIX switch is
set to MDIX (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 shown in the example.
Connecting 100BASE-TX Hubs
You can connect two OfficeConnect hubs together with
100BASE-TX in a number of ways, but for simplicity we
recommend the following method:
1
Connect the highest-number port (port 4 on TP400,
port 8 on TP800, port 12 on TP1200) of the lower hub
to any port of the upper hub.
2
Set the MDI/MDIX switch on the lower hub to MDI (in).
If you use the highest-number port of the upper hub
ensure that its MDI/MDIX switch is set to MDIX (out).
