PREPARING FOR INSTALLATIONXEROX DOCUPRINT 4050/4090 IPS INSTALLATION PLANNING GUIDE 4-7Connectivity requirementsA Token Ring network or an Ethernet local area network runningTransmission Control Protocol/Internet Protocol (TCP/IP) is thenetwork communication system that may be used to transportdocuments from the host to the IPS. This is an alternative to thechannel-attached configuration, in which data is transmitted via busand tag cables and the HCU.Note: The TCP/IP connectivity option is not available in a VM orVSE environment. However, a printing system with PSF/2 orPSF/6000 can attach to a PSF/VSE system and the PSF/2 or PSF/6000 can furnish the TCP/IP support for the IPS printer.Ethernet specificationsThe Ethernet connection to the printer controller processor must becompatible with the Institute of Electrical and Electronics Engineers(IEEE) 802.3 standard.The Ethernet interface on the processor is a 10Mb/sec twisted pairstandard (10BaseT and 100BaseT). The AUI (for SuperSPARC) orthe MII (for UltraSPARC) Coax Ethernet is enabled with an adaptercable.Work with your system administrator to assess what type of networkyou have and what modifications need to be made to supply anEthernet connector to the printer controller processor.Token Ring specificationsThe Token Ring connection must be compatible with the Institute ofElectrical and Electronics Engineers (IEEE) 802.3 standard. Theprinter controller processor has a 4MB Token Ring interface.Channel-attached specificationsFor an online configuration with an IBM host system, the followingcables must be available:• Bus and tag cables (bus in, bus out, tag in, tag out)• Emergency power off (EPO) cable (optional)• Terminators (if necessary, due to location on channel).For your convenience, it is possible to order the bus and tag cablesfor the printer through Xerox a purchase-only basis.
