Troubleshooting
7800 Dx50/Dx60 only, PDT disabled
Warning/Halt
PDT is full of multi-bit entries as another
MBE occurred. Verify PDT level with PCD
PDT command and replace failed SIMM
pair
7801 Dx50/Dx60 only, Overwrite single bit error
with MBE in PDT
Check PDT level with PDC PDT command
7802 Dx50/Dx60 only, Duplicate PDT entry Contact the response center
7803 Dx50/Dx60 only, EEPROM fault while
updating PDT
Replace Processor/Memory Board
7804 Dx50/Dx60 only, PDT table is full of MBE Verify PDT level with PDC PDT command
and replace failed SIMM pair
7D03 Dx50/Dx60 only, MSI read time-out (HPMC,
caused by an invalid memory address)
1. Replace Processor/Memory card
2. Analyze PIM dump
7D04 Dx50/Dx60 only, MSI write time-out
(HPMC, caused by an invalid memory
address)
1. Replace Processor/Memory card
2. Analyze PIM dump
7D05 Dx50/Dx60 only, Processor/Memory bus
parity fault (HPMC)
Replace Processor/Memory card
7D06 Dx50/Dx60 only, Write bomb fault
(Processor/Memory bus parity error
detected on incoming data)
Replace Processor/Memory card
7D07 Dx50/Dx60 only, Memory address fault
(HPMC)
Replace Processor/Memory card
7D08 Dx50/Dx60 only, Multi-bit memory fault
(HPMC)
Verify PDT level with PDC PDT command
and replace failed SIMM pair
7D09 Dx50/Dx60 only, Single bit memory fault
(HPMC, Unexpected HPMC during memory
self test
1. Replace Processor/Memory card
2. Analyze PIM dump
7D0A Dx50/Dx60 only, Address did not map to
bank (HPMC)
Replace Processor/Memory card
7FXY Memory HPMC error Y = SIMM pair number, replace SIMM pair
indicated by Y
