Cascaded Short-Wave Hub Topology

The example in Figure 5 shows two model S10 hubs connected in a cascade topology.
Cascaded short-wave hubs use one port on each hub for the hub-to-hub connection. Such a
configuration increases the potential distance between nodes in the loop an additional 500
meters. The maximum distance between the server and FC-AL devices with cascaded
short-wave hubs is 1500 meters (1.5 km).

HP-UX Server
or
HP NetServer
NOTE: Connecting HP-UX
servers and HP NetServers
to the same hub is NOT
a supported configuration.
Cascaded hubs must have the same firmware versions to operate properly. If you are using
Fibre Channel Manager to manage cascaded hubs, configure the hub that has the LAN
(ethernet) connection as a parent hub and the remaining hub as a child hub (see
Configuring Cascaded Hubs on page 60).
