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:
Occasional
Persistent

Then they may be due to:
Statistical buffer sizing
Circuit pack congestion that requires redistribution of traffic load
Counter Test
Test
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.
Could not allocate the necessary system resources to run test.
Internal system error.
1. Retry the command at 1-minute intervals, up to 5 times.
2. If the problem persists, escalate the problem.
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.
Circuit pack detects no errors.
