Dedicated LAN for SWAN Concentrators

The dedicated LAN for SWAN concentrators can connect only to SWAN or SWAN 2

concentrators, the Ethernet ports on E4SAs and FESAs that connect to the SWAN

concentrators, and Ethernet switches or hubs provided by HP.

Secure Operations LANs

A secure operations LAN can connect to many clients and servers and might or might

not be connected to routers and bridges. NonStop S-series servers can connect to

secure operations LANs using E4SA Ethernet ports that are not connected to SWAN

concentrators. Routers and bridges are supported for SWAN concentrators beginning

on the G06.06 RVU.

For more information on the secure operations LAN, see the NonStop S-Series

Hardware Installation and FastPath Guide or the TSM Configuration Guide.

Note. System consoles can be connected to a secure operations LAN that connects to the

Ethernet ports on an E4SA, FESA, GESA, or G4SA. This LAN configuration provides extra

flexibility in placing system consoles but does not replace the dedicated service LAN, which is

required for use of Low-Level Link and Notification Director applications in OSM or TSM. See

Dedicated Service LAN for OSM or TSM
