Chapter 1: Introducing the IBM 5500 Express IP Control
Unit
The 5500 Express IP Control Unit allows you to connect network stations or
personal computers equipped with an IBM Express Twinax adapter to a
remote AS/400 system. The unit establishes these connections using
Transmission Control Protocol/Internet Protocol (TCP/IP) available in
Windows 95, 98 and NT workstations and servers. The 5500 Express IP
Control Unit manages traffic between the clients and the AS/400.
Figure 1: Example of the IBM 5500 Express IP Control Unit
Although the clients physically connect to the twinax cable, these connections
appear to the client’s Internet Protocol (IP) applications as a local area
network (LAN) connection. Available in the following models, the IBM 5500
Express IP Control Unit allows
a maximum of 56 twinax connections:
