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, to suit your needs.
When wall mounting your hub, ensure that it is within
reach of the power outlet.
You need two suitable screws. Ensure that the wall you
are going to use is smooth, flat, dry and sturdy. Make
two screw holes which are 142 mm (5.6 in) 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 3 mm (0.12 in) 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 eight 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 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 port 8 to connect a workstation, ensure
the MDI/MDIX switch is set to MDIX.

Connecting OfficeConnect Hubs Together

You can increase the number of workstations that can
connect to your network by adding more OfficeConnect
hubs.

Connecting 100BASE-TX Hubs

You can connect two O fficeConnect hubs together with
100BASE-TX in a number of ways, but for simplicity we
recommend the following method:
Co nnect port 8 of the lower hub to any port of the
1
upper hub (as shown in the diagram), using a cable not
longer than 5m eters (16.4 feet) .
Set the MDI/MDIX switch on the lower hub to MDI (in).
2
If y ou use port 8 of the upper hub ensure that its
MDI/MDIX switch is set to MDIX (out) .
To comply with 802.3 Fast Ethernet specifications, you
can only connect two OfficeConnect Hub 8/TP100s
together.
Correct Hub Connections Using 100BASE-TX
C onnecting to 10BASE-T Networks
Your OfficeConnect Hub can be connected to a
10BASE-T network through a bridge/switch. For further
details contact your supplier.
C hecking Hub Connections
When you have connected your hubs, power them on.
The Port Status LEDs for the ports you have used should
be green. If they are not, check your connections .

Spot Checks

At frequent intervals, visually check that:
The Alert LED is not lit — this is the best way to find out
if there are problems with your network
Case vents are not obstructed
Cabling is secure and not pulled taut
