_ FCO 9XXX-O011, ALPHA particle effects causing intermittent errors ______________________________________________________________________________ | DIGITAL FCO CATEGORY PAGE 1 | | [O] OF 5 | |______________________________________________________________________________| | FIELD CHANGE ORDER NUMBER: 9XXX-O011 | |______________________________________________________________________________| | APPLICABILITY: This "O" coded FCO should be installed on all VAX 9XXX | | systems configured with any VECTOR ACCELERATOR CPU OPTIONs and all field | | spares should be upgraded at the same time. This FCO incorporates ECO | | #P1018-A-MR002. This ECO changes the revision of the P1018-AA MCU Multi | | Chip Unit, 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 VAX9000 systems with installed VECTOR | | ACCELERATOR OPTIONs to reflect usage of the MCU with the revision | | indicated on Page 2. | | "Continued on Page 2" | |______________________________________________________________________________| | QUICK CHECK: See Page 2. | |______________________________________________________________________________| | PRE/COREQUISITE FCO: | MTTI HRS | | 9XXX-0003 |See Page 2| |___________________________________________________________________|__________| | TOOL/TEST EQUIPMENT: 1.

(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-O011 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 3 OF 5 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ 4.

Power off the system, disconnect power and lock out the system from AC power source. 6. Replace the identified P1018-AA, VML MCU with the P1018-AA revision "H" supplied in the FCO kit # EQ-01623-03. ------------------------------------------------------------------ | NOTE: REFERENCE THE MCU REMOVAL AND REPLACEMENT PROCEDURE | | CONTAINED WITHIN THE VAX9000 MAINTENANCE GUIDE. | ------------------------------------------------------------------ 7. Re-connect power and remove all lock out from the system's AC power source. 8. Power on the system and wait for the System Initialization to complete. 9. 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]VML.LOG ON >>>SHOW TIME >>>!CUSTOMER = "customer name" >>>!ADDRESS = "street address" >>>!
