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

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).

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
