In a cascaded configuration of model S10 short-wave hubs, connect any port on the first hub to any port on the second hub. Figure 13 includes all 18 nodes in the loop formed by FC-AL Device 1, Hub A, Hub B, and FC-AL Device 2:

–Port 1 on Hub A connects to FC-AL Device 1.

–Port 10 of Hub A connects to Port 1 of Hub B.

–Port 10 on Hub B connects to FC-AL Device 2.

In this configuration, any unused port on Hub A or Hub B can connect to any compatible FC-AL device. This is just one example of cascaded short-wave hubs. The connection between short-wave hubs can occupy any combination of ports.

Note If you plan to use Fibre Channel Manager to manage cascaded hubs, you must 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).

Correct Cabling Example for a Long-Wave Hub

Hewlett-Packard recommends 9-micron, single-mode fiber cable for the long-wave port.

For ports 1 through 9, the short-wave ports, Hewlett-Packard recommends 50-micron multimode fiber cable for new installations but also supports 62.5-micron multimode fiber cable with SC-style connectors in existing installations.
