DEFINING THE PRINTER TO THE HOST: TCP/IP ATTACHMENTE-2 XEROX DOCUPRINT 4850/4890 IPS INSTALLATION PLANNING GUIDE• 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 your IPS Guide to Configuring and Managing the System,chapter 4, “Setting the system configuration,” 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 channel0attached 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 inSYS1.PROCLIB, although your system may use a differentlibrary.)The JES2 PROC has a DD statement (normally HASPPARM),which points to the initialization dataset. (The location of thisstatement is ‘SYS1.PARMLIB(JES2PARM);’ however, youshould always verify the location on your own system.)
