Network Cascade Expansion

Port 12 has an internal circuitry, crossover MDI/MDI-X ability which can be

used to cascade additional devices. This port is internally defaulted to the

MDI-X position for standalone operation.

Network expansion means that any two hubs may be cascaded through Port

12 of a hub in one stack to any port (other than Port 12) on any other hub in a

second stack. This process allows a single network workgroup to support as

many as 142 workstations (72 ports/stack x 2 stacks = 144 ports - 2 ports for

cascade connections).
