SWAN 2 Concentrator Connections

You can connect more than one SWAN 2 concentrator to an E4SA, FESA, GESA, or

G4SA by using an unmanaged or managed switch (HP recommends this method for

performance reasons). You can also use an Ethernet hub. The SWAN 2 concentrator

has been functionally tested with the following switches and hubs:

•

HP Procurve Series 2300 and 2500 Switches (managed switches)

Information on HP Procurve Series 2300 and 2500 Switches can be found at:

•

HP Procurve 408 Switch (unmanaged switch)

AWAN (Asynchronous Wide Area Network) Access Server

The AWAN access server (3883, 3884, 3885) is a local area network (LAN)-based

communications device that provides the following types of connections:

•

Asynchronous connections to HP 6530 terminals, 6530-compatible terminals,

VT-series terminals, serial printers, and workstation-based 6530 and VT-series

terminal emulators for NonStop S-Series and NonStop K-series servers

•

Remote access for DOS, Windows, and Macintosh computers

•

VT-to-6530 protocol conversion for VT-series terminals attached to a Transmission

Control Protocol/Internet Protocol (TCP/IP) terminal server and LAN-attached

workstation-based VT-series terminal emulators

•

Dial-out connections for LAN-attached DOS, Windows, and Macintosh computers.

Depending on your network, you can configure any or all of these connections. The

AWAN access server supports multiple protocols, enabling users to connect to the

AWAN access server simultaneously using different types of protocols.

AWAN 3886 Servers

The AWAN 3886 servers is a family of asynchronous terminal servers that provide

asynchronous ports for a variety of devices, including terminals, modems, printers, and

similar devices. AWAN 3886 servers support 6530 terminal emulation. TELNET

protocols create sessions between server ports and the following:

Note. The AWAN Access Servers are subject now to controlled availability. The AWAN 3886

Servers are preferred.
