Install the Hub
• Remove the hub and parts from the box.
• Attach the enclosed brackets if you plan to
mount the hub in a rack.
• Install the Intel® Express 330T Stackable Hub
in a rack or on a shelf.
• Plug in the power cord.
Connect
the Devices
• All ports automatically detect the speed of the
device connected to them.
• Connect PCs and print servers to the hub with
straight-through cables.
• Use a crossover cable to connect a hub to
another hub or switch.
• Use a straight-through cable to connect to
another hub or switch when port 1 is set to
MDI.
• Use only CAT 5 UTP to connect 100Mbps
devices. To connect 10Mbps devices, use CAT
3, 4, or 5 UTP.
Rack: Use the three small
screws to attach the
brackets to the hub.

Stack the Hubs
• Unplug the power cords from all the hubs.
• Use the included cascade cable to connect the
hubs. Hubs can be stacked up to five high
(mixed 16- or 24-port).
• When properly connected, the entire stack will
act as a single repeater with two segments
(10Mbps and 100Mbps). The top hub in a stack
will be numbered hub 1.
• The hub’s internal bridge automatically bridges
the 10Mbps and 100Mbps segments (collision
domains) for the entire stack.
Changing MDI/MDI-X
for Port 1
• All ports on the hub are MDI-X. Pressing the
MDI/MDI-X button switches Port 1 to MDI so
you can connect to another hub or switch using
a straight-through cable.

Cascade Cable
Stacking Hubs: The cascade cable
connects from the “Down” connector
on one hub to the “Up” connector on
the hub below it.

• Because the 330T is a Class II hub, never
daisy-chain a 330T hub to a Class I hub running
at 100Mbps with UTP cable. Doing so can lead
to poor network performance.
Add Optional Modules
6
• Both 16- and 24-port 330T hubs can accept
optional modules (refer to the User Guide).
• Use optional modules to manage a stack,
connect to devices at full duplex, or to extend
the network to another building or beyond
100 meters.
