Issue 12 Feb 11 AN-T80020 47
ISL_SEQ_ERR
0x209n
Modules: 8480
Subcode: n = discrepant slice
(1 = ‘upstream’, 2 = ‘downstream’) Sequence counter discrepancies on communications with another
slice.
Return the module for repair.
Action:Slice fault
ISL_DSBL_ERR
0x20A0
Modules: 8480 Request received from other slices to force this slice offline.
This is probably a secondary result of earlier faults, e.g. an 0x8741
from the processor shutting down the slice. If the slice keeps going
offline, return for repair.
Action:Slice OFFLINE
ISL_VOTER_ERR
0x2200
Modules: 8480 A fault has been found on the inter-slice link voter circuit.
Return the module for repair.
Action:Slice fault
BTQ_STALLED
0x2201
Modules: 8480 (Background Test Quantum) The state machine that co-ordinates test
scheduling between slices has stopped. This is likely to be due to a
failure on another slice; check the health of the other slices.
Action:Slice fault
FIU_HOTSWAP_ERR
0x2300
Modules: 8480 A hotswap between modules has completed but the handover of
current drive has not completed. Check the health of both modules to
find the primary cause.
Action:Slice fault
ISL_X_ERR
0x24nn
Modules: 8480 Indicates a fault on the inter-slice communications, and this slice is at
fault. The subcode indicates the detail of the fault in communications
(e.g. synchronization, data check, framing, timing), but the detail is not
relevant to diagnostics.
Return the module for repair.
Action:Slice fault
ISL_Y_ERR
0x25nn
Modules: 8480 Indicates a fault on the inter-slice communications, and the ‘Y’ slice is
at fault. (Subcode as ISL_X_ERR)
Return the module for repair.
On slice A: Y is slice B
On slice B: Y is slice A
On slice C: Y is slice A
Action:’Y’ slice OFFLINE
ISL_Z_ERR
0x26nn
Modules: 8480 Indicates a fault on the inter-slice communications, and the ‘Z’ slice is
at fault. (Subcode as ISL_X_ERR)
Return the module for repair.
On slice A: Z is slice C
On slice B: Z is slice C
On slice C: Z is slice B
Action:’Z’ slice OFFLINE
