Description
To implement Ethernet links, you must purchase the optional Ethernet Communications Package
available from Cisco Systems. This package contains supporting software and the Cisco VCO/4K
EthernetGuide which covers the cabling requirements and implementation strategies. You must provide
cables, transceivers and other components to establish Ethernet links.
Printer Interface
The printer interface on the Storage/Control I/O Module front panel supports parallel system printers
througha 36-pin Centronics-type connector. Figure 4-7 shows the cable wiring diagrams for connecting
the Storage/Control I/O Module parallel port to the system printer.
Note The End of Line (EOL) terminator for the system printer must be defined in the system
database via the Peripheral Configuration screen prior to use (refer to theCisco VCO/4K
System Administrator’s Guide for more information).
