0x1000 Series Codes (Host Interface Unit)
Some of these codes refer to ‘upstream’ and ‘downstream’ slices. The definitions depend on the circuit
concerned, but for the 0x1000 and 0x2000 codes relating to inter-slice communications, the definitions
are:
On slice A: ‘upstream’ = slice B, ‘downstream’ = slice C
On slice B: ‘upstream’ = slice A, ‘downstream’ = slice C
On slice C: ‘upstream’ = slice A, ‘downstream’ = slice B.
FLASH_ERASE_ERROR
0x1000
Modules: All when starting Detects a bad FLASH device or interface whilst erasing firmware.
Return the module for repair.
Action:Slice will not boot
FLASH_WRITE_ERROR
0x1001
Modules:All when starting Detects a bad FLASH device or interface whilst writing firmware.
Return the module for repair.
Action:Slice will not boot
FLASH_VPP_LOW_ERROR
0x1002
Modules:All when starting Detects a bad FLASH device, interface, or low supply voltage whilst
erasing or writing firmware. Check the system supply voltage. If the
supply is healthy, return the module for repair.
Action:Slice will not boot
HIU_OVI_FAULT
0x1004
Modules:All except 8424, 8442,
8480 Checks the operation of the power supply over-current (OVI) trip.
Return the module for repair.
Action:Slice fault
HIU_OVV_FAULT
0x1005
Modules:All except 8424, 8442,
8480 Checks the operation of the power supply over-voltage (OVV) trip.
Check the system supply voltage, else return the module for repair.
Action:Slice fault
HIU_HKAD_TIMEOUT
0x1006
Modules:All This is a timeout on fetching the HIU HKAD data. Detects a faulty
Housekeeping A/D or faulty interface to the HIA. Return the module for
repair.
Action:Slice fault
HIU_ISL_NO_SYNC
0x1007
Modules:Output except 8480 Checks for two fault conditions -
1) test loop synchronization with neighbor slices via ISL (increments
fault filter on failure)
2) test loop stall (4.37 minutes max)
Detects faults in the ISL and/or a dead slice that prevents test
synchronization. Also detects a test loop stall, possibly caused by
excessive switch command transitions that cause test abortion.
If another slice is offline, ignore this fault. Failing this, check for heavy
switching demand. Failing this, return the module for repair.
This fault can lead to a module shutdown on firmware before release
3.5 (see TN20056).
Action:Slice fault
