DEC 3000 Model 500X AXP Service Information

This document is a service and reference guide for Digital service personnel and self-maintaining customers working on the DEC 3000 Model 500X AXP workstation. Published in April 1993, it serves as a supplement to the DEC 3000 Model 500/500S AXP Service Information guide.

The guide provides new information specific to the Model 500X system, including an overview of its CPU, memory subsystem, and network interface, as well as jumper configuration details for the system module. It also details troubleshooting procedures for power and fan failures, comprehensive instructions for removing and replacing Field Replaceable Units (FRUs) like the top cover, bezels, audio module, power supply, disk drives, TURBOchannel modules, regulator module, I/O module, system fans, impingement fan, memory motherboard, memory modules, and the system module itself. An appendix lists recommended FRU part numbers.

For other topics such as console commands, diagnostic testing, SCSI utilities, general troubleshooting, firmware upgrades, monitor alignment diagnostics, and LED codes/error messages, the document refers the reader to the original DEC 3000 Model 500/500S AXP Service Information guide.
