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.

Public LANs

A public 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 public

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 public LAN, see the NonStop S-Series Hardware

Installation and FastPath Guide or the TSM Configuration Guide.

Caution. If your system contains IOAM enclosures, you must have a dedicated LAN for

SWAN concentrators that is separated from the LAN for the rest of the system.

Note. System consoles can be connected to a public LAN that connects to the Ethernet ports

on an E4SA, FESA, or GESA. 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 on page 11-1.
