Connecting Hubs Using 10BASE-T

You can connect hubs together with 10BASE-T in a
number of ways, but for simplicity we recommend the
following method:
Starting from the bottom, connect port 16 of the lower
1
hub to port 15 of the hub immediately above. Repeat for
each hub (as shown in the diagram).
Set all MDI/MDIX switches to MDI (in) except for the top
2
hub (the one with port 16 not connected to another
hub). This unused port can be connected to a
workstation provided that the MDI/MDIX switch is set to
MDIX (out).

Checking Hub Connections

When you have connected your hubs, power them on.
The Port Status LEDs for the ports you have used on the
hubs should be green. If they are not, check your
connections and the settings of the MDI/MDIX switches.

Spot Checks

At frequent intervals, visually check that:
The Alert LED is off — 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
If you suspect a problem, refer to
page 7.
