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

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.
