Note: The following items should be read and followed carefully by AS/400 system
administrators ONLY.
Required OS Level and PTFs
The IBM 5250 Express TCP/IP software is only supported on AS/400s running
V4R2M0 or later. All previous OS levels must first be upgraded prior to
using this software/driver.
In addition, the following program temporary fixes (PTFs) MUST BE INSTALLED
on your AS/400 in order for the IBM 5250 Express TCP/IP driver to work
properly on your clients:
- Cumulative PTF package C8045420 or later.
- PTF MF18398
- PTF MF18450
These PTFs should be installed and applied BEFORE beginning any TCP/IP over
twinax configuration on the host or clients. If you do not have these PTFs, they can be
obtained through IBM's normal PTF ordering channels. Additions or modifications to the
above PTF list will appear on this web page and in subsequent updates of the README file.
Required 5250 Adapter Hardware for your PC
One of the following IBM 5250 Adapters should be installed in your PC for
TCP/IP connectivity to your supported AS/400. Your AS/400 must be
configured with a 6050 (or newer) WorkStation Controller.
For more detailed information about these IBM Twinax Adapters and IBM
Emulation Software, this link
will take you to the Express Adapter page.
This link will take you to a page
with orderable part numbers for IBM 5250 Adapters capable of using
TCP/IP over Twinax.
Host Configuration Program
It is recommended that all AS/400 system administrators download and
run the IBM 5250 TCP/IP address selection and host configuration program
BEFORE installing the TCP/IP transport driver on any workstations.
This program guides you through the steps necessary to configure your AS/400
for operation with the IBM 5250 Express TCP/IP transport driver. Included
in this program is information on:
- How to choose the proper TCP/IP address ranges for your AS/400
and twinax workstations.
- How to configure the TDLC line and interface to work with the
twinax workstations.
- How to set and change several AS/400 parameters critical to the
operation of TCP/IP over twinax.
