• Use a straight-through cable to connect from port 1 on a hub to any
port on the other hub.
Stacking Hubs
The Express 330T hub uses a unique set of connectors on the back of the
hubs so they can be stacked together. By stacking hubs you can:
• Increase the number of available ports, yet still treat the stack as a
single repeater.
• Use a single Management Module to manage all hubs in the stack.
• Use the hub’s internal bridge so 10Mbps and 100Mbps segments can
communicate.
Guidelines
• You must use the included cascade cable to stack the hubs.
• A stack can consist of any combination of Express 330T hubs (16- or 24-
port versions).
• You can stack up to five Express 330T hubs.
• When cabled correctly, the top hub in a stack is numbered hub 1.
• If there is more than one hub in a stack, only one bridge is active at a
time. The lowest numbered hub (top of the stack) is the active bridge.
• All devices at the same speed are in the same segment (collision domain).
For example, all devices at 10Mbps are in one segment and all devices at
100Mbps are in another.
