Cascading Repeating Hubs
You may cascade up to four repeating hubs in your LAN
(limitations of Repeating Ethernet V2.0/IEEE802.3 hubs). In case
more hubs need to be cascaded, you must use switching hubs.
In the above figure an MDIX port on the hub connects to the
STPro. Therefore, a crossover LAN cable is used.
Note: In case the hub's uplink" port is used to wire the STPro you can use the
included straightthrough LAN cable.
