Model 744 Board Computer Overview Installation Overview CAUTION: Installation Overview Chapter 2 provides step-by-step instructions for attaching and installing accessories in a typical VME card cage, and connecting external devices. Accessories are products that attach to the computer's system board. They must be attached before installing the board computer in a VME card cage. Devices are products used externally to the board computer. Examples are keyboards, monitors, and mass storage devices. Other devices are connected through cables. Depending on your specific application, you may need one or more accessory and device products. Installation instructions for most products used directly with your Model 744 Board Computer are explained in this manual. Chapter 3 presents the installation tasks required to install and configure your board computer. Installation Notes Your Model 744 Board Computer uses micro-miniature connectors for several interface ports. Cable connectors for these ports are very small, but may be positioned so that a slight angle exists between them. This situation has been tested by HP and full functionality is maintained. The Model 744 Board Computer's P2 connector has a local bus on the userdefined pins. Verify that your VME card cage's backplane makes no connections to J2/P2, rows A and C. Refer to IEEE STD 1014-1987, Chapter 7, for more information on use of user-defined pins in VME backplane connectors. 1-7
