DEFINING THE PRINTER TO THE HOST: TCP/IP ATTACHMENTE-2 XEROX DOCUPRINT 96/4635/180 IPS INSTALLATION PLANNING GUIDENetwork configurations – MVSThe IPS printer is supported in all the following configurations,provided that the software prerequisites are installed.• Basic configuration in which the MVS host is attached to a LANusing a Token Ring or Ethernet network adapter card• Remote LAN environment in which there are datacommunication links between the host and the LAN-attachedcontroller• Configurations in which the LAN with the printer attached isconnected to the host-attached controller using LAN devicessuch as routers• Environments with intermediate host systems between theMVS host running PSF and the LAN-attached controller.Note: There may be printer performance and throughputimplications with some of these configurations. It is recommendedthat your network management group be involved with planning thisinstallation.Configuration steps – MVSThe software configuration process for IPS in an MVS or OS/390environment with TCP/IP consists of five major steps:1. Configure the IPS printer for TCP/IP at the GUIRefer to the “Setting the system configuration” chapter of the Guideto Configuring and Managing the System for this graphical userinterface (GUI) procedure.2. Configure the MVS CCU for the MVS host to MVSThe MVS communications control unit (CCU) could be the 3172,3174, or 3745 control unit. To configure it to MVS, you can use eithera hardware configuration definition (HCD) or an MVS configurationprogram (MVSCP). If your control unit and LAN are already installedand operational, skip this step.Note: The AFP1 parameter used when channel-attached IPDSprinters are defined is not applicable in this configuration. It is thecommunications control unit (3172, 3174, or 3745) that is beingdefined to MVS, not the printer’s control unit.3. Configure the PSF printer in JES2 or JES3This section discusses the procedures for configuring the IPS inJES2 or JES3 environments.Configuring in JES2 To configure the PSF printer in JES2, follow these steps:1. Locate the JES2 initialization dataset in the JES2 Startup JCLProcedure (JES2 PROC). (This is normally kept in
