SUMMARY
This article discusses the three ways to connect a Macintosh to a mainframe or AS/400 through SNA Server.



Downstream PU for 3270
On the Macintosh, install a Token Ring card and bind the DLC protocol to it. In SNA Server Admin, configure a downstream connection for the Macintosh. For instructions on setting up downstream connections see Chapter 9 of the SNA Server "Administration Guide."

This configuration works with any Macintosh 3270 emulator that supports 802.2 connectivity.

NOTE: Macintoshes are not supported as Downstream PUs on Ethernet because there is no DLC support for Ethernet on a Macintosh.

NOTE: SNA Server doesn't support 5250 from a downstream PU (DSPU) since 5250 requires independent LU6.2 which is not support through an SNA Server DSPU.

TN3270/TN5250
SNA Server 2.x:

On the Macintosh, install TCP/IP and use any Macintosh TN3270 emulator. On the SNA Server, install the TN3270 Service (\TN3270\setup.bat).

For instructions on how to configure SNA Server Admin for LUA, see Chapter 8 of the SNA Server "Administration Guide." For information on configuring the TN3270 Service, consult the online help in the TN3270 Admin program.

SNA Server 3.x:

SNA Server 3.x was enhanced with a TN5250 Service. To use this service, install TCP/IP on the Macintosh and use any TN5250 emulator for your 5250 sessions.

For instructions on how to configure APPC LUs for use with the TN5250 service or for instructions on how to configure the TN5250 Service, consult the online documentation within SNA Server Manager.

TN3270 remains the same under 3.x, except the adminstration is built into SNA Server Manager and it is installed as an optional component within SNA Server 3.x's main setup program.

Windows NT Services For Macintosh
Configure a Windows NT machine for Services for the Macintosh, and then run Attachmate's IRMA Workstation for Macintosh v4.0 or greater and follow the instructions outlined in the "Configuring for a Microsoft SNA Server" section in Chapter 2 of the Attachmate Irma Workstation for Macintosh User's Guide.

For instructions on how to setup Services for Macintosh on a Windows NT machine see "Services for Macintosh" install guide that ships with Windows NT Server.
