	Module A	Cascade

• Unplug the power cords from all the hubs.

• Use the included cascade cable to connect the	Hub 2	Up
hubs. Hubs can be stacked up to five high		Down
	Module A	Cascade
(mixed 16- or 24-port).
• When properly connected, the entire stack will	Hub 3	Up
act as a single repeater with two segments		Down
(10Mbps and 100Mbps). The top hub in a stack	Module A	Cascade
will be numbered hub 1.
	Cascade Cable

•The hub’s internal bridge automatically bridges the 10Mbps and 100Mbps segments (collision domains) for the entire stack.

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

Changing MDI/MDI-X

5 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.
•	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.
