AN-T80020 Diagnostics Procedure
Issue 12 Feb 11 AN-T80020 51
HSIU_RAM_PAGE_FAULT
0x5006
Modules:8442 Detects any fault in free RAM that is related to RAM paging. Return the
module for repair.
Action:Slice OFFLINE
OFIU_PLL_FAULT
0x5006
Modules:8472 Detects faults in the field interface timing control circuitry (the test
schedule is locked to the AC cycle). These faults may be a secondary
effect of other faults. If the fault is persistent, return the module for
repair.
Action:Slice fault
IFIU_FIUCTRL_TEST_FAULT
0x5007
Modules:Input Detects serious failures in the FIU comms link path between the IHIA
and IFIA, using an echoed token. Return the module for repair.
Action:Slice OFFLINE
OFIU_ISLSEQ_FAULT
0x5007
Modules:8472 Detects failures in the FIU comms link path between slices using a
sequential counter. Return the module for repair.
Action:Slice fault
FIU_DSCRP_TST_LATE
0x5008
Modules: 8442, 8472 The slice discrepancy data collection has been delayed so that the data
from each slice is now too far apart to be relevant. Check for other
faults that may explain the delay; otherwise return the module for repair
if the fault appears again after pressing Reset.
Action:Slice fault
HSIU_RELAY_CMD_
CHECKSUM ERR
0x5009
Modules:8442 Detects errors in the commands to output relays. Return the module for
repair.
Action:Slice OFFLINE
OFIU_XMON_CNT_ALL_
FAULT
0x501n
Subcode: n = quadrant (0 to 3)
Modules:8472 All channel PICs have failed to respond properly on one quadrant
suggesting a common fault. Similar to 56mn (indicates a single PIC at
fault). Return the module for repair.
Action:Slice fault
OFIU_ISL_SW_TEST_DISCREP
0x5014
Modules:8472 Software test register is discrepant between this slice and the other
two. This fault may be a secondary effect of other faults. If the fault is
persistent, return the module for repair.
Action:Slice fault
SFIU_IO_TEST_REG_SLICE_
DISCREP
0x5014
Modules:8442 Test control register is discrepant between this slice and the other two.
If the fault is persistent, return the module for repair.
Action:Slice fault
SFIU_IO_TEST_ERR
0x5015
Modules:8442 Test control register is different to other slices but no slice fault
indicated. If the fault is persistent, return the module for repair.
Action:Slice fault
SFIU_TEST_CTRL_ERR
0x5016
Modules:8442 Incorrect data in test control register. If the fault is persistent, return the
module for repair.
Action:Slice fault
