Local Area Network (LAN) Driver and Interrupt Handlers (DIHs)
NonStop TCP/IP processes can interface to the network through the ServerNet LAN
Systems Access (SLSA) subsystem. The SLSA subsystem provides QIO-based driver
and interrupt handlers (DIHs) that allow NonStop TCP/IP processes to connect to a
LAN adapter. The SLSA subsystem is preconfigured and started during the system
load sequence.
For more information on the SLSA subsystem and LAN adapters, see the LAN
Configuration and Management Manual.
ServerNet Wide Area Network (SWAN) Concentrator
The SWAN concentrator is a communications device that provides wide area network
(WAN) connections. HP recommends that you configure the SWAN concentrator in the
same processor pair as the Expand line-handler processes.
For more information on the SWAN concentrator, see the WAN Subsystem
Configuration and Management Manual.
