_ DEC-O-LOG for 64XMX _ DOL, 64XMX-S001, VAX 64XMX Systems, Nov 89 PROBLEM: VAX 6000 series system design does not permit unqualified personnel to access the interior of the system cabinet. Embedded storage controls and indicators cannot be accessed without opening cabinet front door. FIELD EFFECTIVITY: This "S" coded FCO is being implemented on early shipments of the VAX 6000 series systems containing embedded storage. It does not change the revision of the systems. QUICK CHECK: Front door should have opening for embedded storage. FCO KIT ORDERING EQ-01563-01 FCO, Parts FA-04874-03 FCO Document _ DOL, 64XMX-O002, VAX 64XMX Systems, Feb 91 PROBLEM: This FCO solves problems with T2015 as follows: 1.) MOVC5 and CMPC5 Instructions with length values of zero may change an internal temp. register causing the next instruction to fail. 2.) V1.0/V2.0 Console/Diag ROMS do not support Vector/dual Vector options respectively. 3.) The PC may be aligned by plus or minus 4 bytes during multi-processing operations. 4.) The VC chip can, in certain instances, resend an instruction to an attached Vector Processor that has already been executed. 5.) Dendritic growth on LDCCs can cause intermittent system interrupts. This FCO solves problems with T2017 as follows: 1.) Load/ store chips could hang while executing a STORE class instruction due to INVALIDATE traffic in dual Vector configurations. 2.) Excessive undershoot and ringing on duplicate tag address may cause reliability and timing problems. 3.) Vectl chip fix - a combination of instructions if used together break the architectural spec. 4.) Dual Vector configurations may hang and abort processes under a particular Vector Parallel Decomposed application. 5.) Dual Vector configurations under heavy system loads may align internal data movement events such that data integrity could be compromised. FIELD EFFECTIVITY: This FCO should be installed in all 64XMX systems and spares. It incorporates ECOs T2015-TW007, T2015-TW008, T2015-TW010 and T2017-LTN04. QUICK CHECK: T2015--component at location E29 is p/n 21-25087-09 for Rev "L"; T2015-YA--component at location E29 is p/n 21-25087-09 for Rev "D" and for T2017 PAL at location E6 is 23-210K4-00 for Rev "J".

FIELD EFFECTIVITY: Upgrade applicable 6000-4XX system CPU modules to a minimum revision "AM" ONLY WHEN ADDING A DWMVA option to an existing system. Also, ensure a spare module rev. "AM" is available to support this at the SDU. This FCO incorporates ECO #T2015-TWO011. SOLUTION: Upgrade applicable 6000-4XX system CPU modules upon installation of the DWMVA add-on option. Use module part revision "AM" or higher. QUICK CHECK: Component at location E97 is p/n 23-308E9-00 for rev. "AM". Component at location E77 should be p/n 23-307E9-00. The DEC on-site labor charge will be the time required to install and test the FCO at the then current hourly rate. FCO KIT ORDERING EQ-01630-03 T2015-00 Module Minimum Rev.
