Installation 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. Figure 13 Cascaded Short-Wave Hub Configuration Short-Wave Hub A Short-Wave Hub B ..... ..... FC-AL Device 1 FC-AL Device 2 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.

Procedure 5: Plan the FC-AL Connections
33
Installation
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.

Cascaded Short-Wave Hub Configuration
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.
