0
Backpressure was ignored at least once since this latch was read.
Backpressure was not ignored since this latch was read.
Refer to section 3 “Fault Tolerance” starting on page 44 for more information.
SE_INPUT_PORT_FAIL_LATCH
(14:11)
Bit 14 corresponds to port 3, bit 13 corresponds to port 2, bit 12 corresponds to port
1 and bit 11 corresponds to port 0 as follows:
1
One of the following was detected at least once since this latch was
read:
•
•
•
•
Bad SOC pattern
invalid cell code
bad idle cell code
fabric out of synch
0
None of the above has been detected since this latch was read.
Refer to section 3 “Fault Tolerance” starting on page 44 for more information.
BP_REMOTE_FAIL_LATCH
(10:7)
Bit 10 corresponds to port 3, bit 9 corresponds to port 2, bit 8 corresponds to port 1
and bit 7 corresponds to port 0 as follows:
1
0
The forward data path was bad at least once since this latch was read.
The forward data path was not bad at least once since this latch was

Bit 6 corresponds to port 3, bit 5 corresponds to port 2, bit 4 corresponds to port 1
and bit 3 corresponds to port 0 as follows:
1
The BP_ACK_IN(3:0) line did not have the required pattern at least
once since this latch was read.

The empty queue depth threshold was crossed in either direction since
this latch was read.
The empty queue depth threshold was not crossed in either direction
since this latch was read. The congestion is declared to have been
relieved when the queue depth crossed back above twice the configured
congestion threshold.
