Digital AXPpci 233XL Module Set OEM

This OEM Design Guide provides system integrators with comprehensive details for integrating the Digital AXPpci 233XL Module Set into standard or custom applications. The module set, identical to that used in Digital's AlphaStation 400 Model 4/233, features a DECchip 21064A Alpha AXP™ 233 MHz RISC processor and supports DEC OSF/1 AXP and OpenVMS AXP operating systems.

The document outlines the physical, performance, and operational characteristics, including detailed descriptions of the Core Module Assembly, Main Logic Board (MLB), CPU module, SIMMs, and ISA/PCI option modules. It provides extensive pin-out specifications for various connectors (DC power, floppy, IDE, keyboard/mouse, LEDs/switch, parallel, PCI, SCSI-2, serial, SIMM, speaker) and explains the functions of configuration jumpers. Diagnostic LED display codes and beep codes are also included for troubleshooting.

Furthermore, the guide covers critical environmental data such as cooling requirements, DC power input specifications (including power sequencing and POWER OK signal characteristics), ESD considerations, EMC considerations, and reliability data (MTBF). Appendices list related documents, module kit ordering information, and a comprehensive connector summary. The overall aim is to equip integrators with all necessary information for successful physical mounting, electrical interfacing, and adherence to environmental constraints.
