SYSTEM OVERVIEW
1-4 XEROX DOCUPRINT 96/4635/180 IPS SYSTEM OVERVIEW GUIDE
Host connectivity options
The IPS can be set up to receive data from a host in one of two ways:
• Over a channel with bus and tag cable connection, via the Host
Channel Unit (HCU)
• Through a Token Ring or Ethernet interface, using TCP/IP
protocol (not available in a VM or VSE host environment)
Note: A transmission rate of at least 16 megabits per second
should be used with a Token Ring interface on the IPS. (Overall
performance depends on network traffic and job density.)
Channel-attached configuration Figure 1-1 illustrates the components of a channel-attached IPS.
This configuration requires a Host Channel Unit (HCU) to interface
between the host channel and the IPS controller.

TCP/IP configuration If you are using Token Ring or Ethernet with TCP/IP, as shown in
figure 1-2, the bus and tag cables and the HCU are not required.
