_ FCO 9XXX-O008, ALPHA particle effects causing intermittent errors ______________________________________________________________________________ | DIGITAL FCO CATEGORY PAGE 1 | | [O] OF 5 | |______________________________________________________________________________| | FIELD CHANGE ORDER NUMBER: 9XXX-O008 | |______________________________________________________________________________| | APPLICABILITY: This "O" FCO should be installed on all VAX 9XXX systems and | | all field spares should be upgraded at the same time. This FCO incorporates | | ECOs #P1003-A-MR003 and P1004-A-MR002. These ECOs change the revision of | | both the P1003-AA MCU Multi Chip Unit and the P1004-AA MCU to revision H02. | |______________________________________________________________________________| | PROBLEM & SYMPTOM: The problem symptoms may range from undetected intermit- | | tent, incorrect results, to non-recoverable data parity errors. The symptoms | | resulting from these anomolies are difficult to define or model specifically.| | They are caused by ALPHA particle effects. These changes simulate the | | exposure due to ALPHA particles and add further circuit stability by use of | | dual feedback latch. | |______________________________________________________________________________| | SOLUTION: | | 1. Retrofit all current customer systems to reflect usage of MCUs and | | revisions indicated on Page 2. | |______________________________________________________________________________| | QUICK CHECK: See Page 2. | |______________________________________________________________________________| | PRE/COREQUISITE FCO: | MTTI HRS | | 9XXX-O003 | 4.0 Hrs. | |___________________________________________________________________|__________| | TOOL/TEST EQUIPMENT: 1.

THE P1003-AA, MUL MCUs AT REVISION "E" AND "F" ARE OF ACCEPTABLE REVISION DUE TO THE FACT THEY HAVE BEEN IMPLEMENTED WITH NEW ENCAP- SULANT ON THE MULX MARCO CELL ARRAYS. Part # Description OLD REV NEW REV ------ ----------- ------- ------- F6-P1003-AA MUL, EBOX MULTIPLY MCU D H F6-P1004-AA FAD, EBOX FLOATING UNIT E,F H 2. Update logistics spares to reflect the latest revision of MUL MCU and FAD MCU, indicated above. NOTE: ALTHOUGH THE P1003-AA, MUL MCUs AT REVISIONS "E" AND "F" ARE ACCEPTABLE WITHIN OUR CURRENTLY INSTALLED SYSTEMS, ALL SPARES SHOULD BE UPDATED ON THE P1003-AA, MUL MCUs TO REVISION "H". MUL MCU SPARES AT REVISION "H" WILL IDENTIFY A SCREEN TESTED MUL MCU SPARE. QUICK CHECK (Continuted) ------------------------ Look for the following revisions on the MUL MCU and FAD MCU within current VAX9000 customer systems; Part # Description Acceptable Revision ------ ----------- ------------------- P1003-AA MUL, EBOX MULTIPLY MCU E, F, H P1004-AA FAD, EBOX FLOATING UNIT H MTTI (Continued) ---------------- This FCO will take approximately 4.0 Hrs. (includes shutdown, removal, installation, and test time) for a UNI CPU configuration. Field Installation Synopsis --------------------------- 1. Perform Normal Operating System Shutdown Procedures. 2. Turn Operator's Console "STARTUP" Switch to "HALT" position. 3. Show configuration of MCUs via VAX9000 console within each CPU that exists within system. >>>SHOW CONFIGURATION/CPU:ALL _ _ _ _ _ _ _ | FCO 9XXX-O008 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 3 OF 5 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ 4. Identify if any of the P1003-AA, MUL MCUs are at or below revision "D". 5. Identify if any of the P1004-AA, FAD MCUs are at or below revision "F". ------------------------------------------------------------------------ | NOTE: THE FOLLOWING SET OF STEPS ARE TO BE DONE ON EACH CPU | | SEPARATELY IN A MULTI CPU CONFIGURATION AND NOT CONCURRENTLY | | ACROSS MULTIPLE CPU PLANARS!!!! | ------------------------------------------------------------------------ 6. Power off the system, disconnect power and lock out the system from AC power source. 7. Replace the identified P1003-AA, MUL MCU with the P1003-AA revision "H" supplied in the FCO kit # EQ-01623-01. 8. Replace the identified P1004-AA, FAD MCU with the P1004-AA revision "H" supplied in the FCO kit # EQ-01623-02. ------------------------------------------------------------------------ | NOTE: REFERENCE THE MCU REMOVAL AND REPLACEMENT PROCEDURE | | CONTAINED WITHIN THE VAX9000 MAINTENANCE GUIDE. | ------------------------------------------------------------------------ 9. Re-connect power and remove all lock out from the system's AC power source. 10. Power on the system and wait for the System Initialization to complete. 11. Verify that all the CPU Diagnostics run without error. ------------------------------------------------------------------------ | NOTE:THE "x" IN THE FOLLOWING COMMAND LINES REPRESENT THE TARGET CPU| ------------------------------------------------------------------------ >>>SET LOGGING/FILE=[CONSOLE]MUL_FAD.LOG ON >>>SHOW TIME >>>!CUSTOMER = "customer name" >>>!ADDRESS = "street address" >>>!
