6. Verify FC-AL Cabling Correct cabling example, HP FC-AL short-wave hub (HP A3724A) In a cascaded configuration of HP FC-AL short-wave hubs, use a short-wave cable to connect any port on the first HP FC-AL hub to any port on the second HP FC-AL hub. In the following example, Port 1 on Hub A connects to FC-AL Device 1; Port 10 of Hub A connects to Port 1 of Hub B; and Port 10 on Hub B connects to FC-AL Device 2. Any shortwave FC-AL device or hub can connect to Port 10 of a short-wave hub. Hub A Hub B To Device 1 To Device 2 Figure 28. Cascaded HP FC-AL short-wave hub (HP A3724A) configuration Correct cabling example, HP FC-AL long-wave hub (HP A48394A) In a cascaded configuration of HP FC-AL long-wave hubs, use a long-wave cable to connect the long-wave port (Port 10) on the first HP FC-AL hub to the long-wave port (Port 10) on the second HP FC-AL hub. In the following example, Port 1 on Hub A connects to FC-AL Device 1; Port 10 of Hub A connects to Port 10 of Hub B and Port 1 on Hub B connects to FC-AL Device 2. This is the only correct way to cascade HP FC-AL long-wave hubs. Hub A Hub B To Device 1 To Device 2 Figure 29. Cascaded HP FC-AL long-wave hub (HP A4839A) configuration 31
