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 Ethernet Guide 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 through a 36-pin Centronics-type connector. Figure 4-7shows 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 the Cisco VCO/4K System Administrator’s Guide for more information).
