AXIS 570/670 MIO User’s Manual 39
SNA
Host Set-up - IBM Mainframe
This section describes the changes that are necessary on the IBM host
system.
Before you begin
❏ You have decided that the AXIS 570/670 MIO is going to run in
3270 CU mode.
❏ Have the serial number, found on the back of the AXIS 570/670
MIO circuit board, available.
Set-up
This section shows how to establish communication between an AXIS
570/670 MIO and a mainframe connected to a LAN through a
LAN-to-host gateway. From VTAM’s point of view, the AXIS
570/670 MIO will appear as a LAN attached 3174 DSPU
(DownStream Physical Unit) running SNA PU2.0 and should be
defined as such.
To set-up your host you will typically have to do the following:
1. Make sure that a VTAM Logon-mode entry is available for your
AXIS 570/670 MIO.
2. Locate the VTAM Definition for the Major Node where the Print
Server definition is to be placed. Using a channel attached 3174
DSPU as a gateway to the host, the VTAM Major Node definition
is typically a Local Major Node. If you are using a remotely
attached gateway via a 37X5 communications controller into the
mainframe, you will be working with a Switched Major Node
definition. Add the Print Server PU and LU definitions to the
major node definition.
3. Verify the communication.
The examples below are based on samples given in “VTAM
Customization” (IBM part no: SC23-0112), with some changes to
optimize use for AXIS 570/670 MIO. VTAM for MVS is assumed. The
configuration for VM and VSE is similar. Please note that the
configuration can vary widely from system to system.
