Receive FIFO Overflow Error Counter Test (#596)
This test is non-destructive. When the CLAN circuit pack detects packet bus
buffer overflow, it increments the error on the FIFO Overflow error counter. This
test reads and clears the counter.
If errors are: Then they may be due to:
Occasional Statistical buffer sizing
Persistent Circuit pack congestion that requires redistribution of traffic load

Result Description/Recommendation
2000 ABORT Did not receive circuit pack test response within the allowable
time period.
1. Retry command at 1-minute intervals, up to 5 times.
2. If the problem persists, reset the circuit pack (reset board
UUCSS).
3. If the problem persists, replace the circuit pack.
2100 ABORT Could not allocate the necessary system resources to run test.
2500 ABORT Internal system error.
1. Retry the command at 1-minute intervals, up to 5 times.
2. If the problem persists, escalate the problem.
1-10 FAIL Circuit pack detects overflow errors. The error code indicates the
value of the on-board error counter.
1. Retry the command at 1-minute intervals, up to 5 times.
2. If the test continues to fail, execute the Packet Interface Test
(#598) (test board UUCSS).
3. If Packet Interface Test (#598) fails, refer to Packet Bus repair
procedures.
PASS Circuit pack detects no errors.
