HP Intrusion Prevention System S10, L10 manual Cascaded Long-Wave Hub Topology

Cascaded Long-Wave Hub Topology

Cascaded FC-AL, non-OFC, model L10 long-wave hubs use the long-wave port for the hub- to-hub connection. The maximum supported distance between cascaded long-wave hubs with single-mode 9 micron cable is 3 km. The maximum distance between a server and FC- AL devices on cascaded long-wave hubs is, therefore, 4000 meters (500 m + 3000 m +

500m). Under certain conditions, cascaded long-wave hubs are supported up to 10,000 meters (10 km) (see page 105 for more information). The 10-km capability only applies to long-wave hubs connected to HP-UX servers.

Caution When cascading long-wave hubs, only connect long-wave ports to long-wave ports or short-wave ports to short-wave ports.

Ports 1 through 9 on each long-wave hub are for connections to FC-AL devices. Ports 1 through 9 can also be used in a cascaded configuration; however, the maximum distance between hubs decreases from 3000 meters to 500 meters.
