There are two slots on the underside of the
OfficeConnect hub which are used for wall mounting.
You can mount the unit with the LEDs facing upwards or
downwards, to suit your needs.
When wall mounting the u nit , 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 unit and locate it over
the screw heads. When in line, gently push the unit on
to the wall and move it downwards to secure. When
making connections, be careful not to push the unit up
and off the wall.
CAUTION: Only wall mount single unit s, do not wall
mount stacked unit s.
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 10BASE-T cables to any
of the hub's sixteen 10BASE-T RJ45 ports.
10BASE-T cables are very easy to use. To connect a
10BASE-T 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 16 to connect to 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 more OfficeConnect
hubs. You can use either 10BASE-T or 10BASE-2 (Coax) to
do this:
With 10BASE-2 (Coax) you can connect up to 30 hubs on
a single segment, leaving all of the RJ45 ports free.
With 10BASE-T you can connect up to four hubs in
series.
CAUTION: Do not connect the same two hubs together
using both 10BASE-T and 10BASE-2 (Coax). This causes a
network loop.
Connecting Hubs Using 10BASE-2 (Coax)
When using 10BASE-2 (Coax) cable, it is important that
both ends of the segment are properly terminated with
50 Ohm terminators (end pieces).
Only use 50 Ohm 10BASE-2 (Coax) cables and use a 'Y'
piece for each hub. You can use 'T' pieces but 'Y' pieces
provide optimum clearance of the other ports.
Connect a 10BASE-2 'Y' piece to each of your hubs.
Daisy-chain each 'Y' piece with 10BASE-2 (Coax) cable to
form a single segment (as shown in the diagram).
Remember to terminate the two free ends of the
segment by fitting terminators (end pieces).
To disconnect a 10BASE-2 (Coax) cable, twist each
connector counter-clockwise to unlock it, and remove it.
