Optional Information
4
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
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.
6
Add Optional Modules
• 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.
