Changing MDI/MDI-X
for Port 1
Stack the Hubs
• 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.
• 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.
• 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.
• 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.

connects from the “Down” connector
on one hub to the “Up” connector on
the hub below it.
