_ DEC-O-LOG for 7XXX _ DOL, 7XXX-F001, Capacitor C49 in VAX 7xxx DEC 92 PROBLEM: Capacitor C49 has been found in some blower assemblies to overheat and fail. The failure will be accompanied by smoke and caustic odors that accompany the destruction of the capacitor. FIELD EFFECTIVITY: This FCO is applicable to all W/W shipments of VAX 7XXX systems, which have a blower (DEC P/N 12-35173-01) with serial numbers in the following range: S/N 245 through S/N 675. QUICK CHECK: The blowers can be identified by the S/N. Blowers with a S/N above 675 or which have been reworked and marked with "Green Dots" do not require this FCO and are suitable for use. FCO KIT ORDERING EQ-01656-01 Parts only FA-04992-01 FA Document only _ DOL, 7XXX-F002, CCL module/Door catches FEB 93 PROBLEM: The CCL module, 54-20300-01, in the VAX 7XXX system has an air pressure sense switch that does not meet design requirements. These switches cause intermittent system shut down due to a false air flow loss indication The rev. C01 door catches cause the cabinet doors to be very difficult to open. FIELD EFFECTIVITY: This FCO is applicable to all VAX 7XXX systems that have a CCL module, P/N 54- 20300-01 at rev. J03 or below and all systems that have rev. C01 door catches. QUICK CHECK: The CCL can be identified by the rev. level. Modules at rev. J03 and below should be re worked. Doors should open easily, if not replace the catches.

All systems were shippped FCC compliant. Spares shipped prior to April '93 are suspect. FIELD EFFECTIVITY: This "F" coded FCO will up grade field spares used on the VAX and DEC 7000 and 10000 systems. (See FCO Kit contents for affected spares.)

A01, B01, C01, and D01) CPU modules with new E2040-YA rev. E01 CPU module. These FCOs incorporate the following ECOs: (1) E2040-AB-TWO001 and (2) E2040-YA-TWO003. This FCO will also upgrade all 182 MHZ systems to 200 MHZ performance. PROBLEM & SYMPTOM: (1) System currently has certain memory configuration restrictions that are checked by console prior to booting the system. The console will display the following message "INVALID MEMORY INTERLEAVING- boot disallowed", when a boot is attempted on the system. (2) The Cache error correction routine does not properly correct cache signal bit errors. This problem has the potential to severly disrupt normal system operation. SOLUTION: Replace the E2040-AA(all revs); E2040-AB(all revs) and E2040-YA(rev. A01, B01,C01,D01) CPU modules as per a procedure (see below) with new E2040-YA rev. E01 module, minimum revision must be E01. NOTE: All modules at rev. E01 need a minimum Console version V2.5 QUICK CHECK: Verify that all System modules are E2040-YA at the minimum Rev E01 and the Spares kits are at rev E01.
