CLAN-BD (Control LAN Circuit Pack)
Issue 1 June 2005 803
Receive FIFO Overflow Error Counter
Test (#596)
This test is nondestructive. When the C-LAN 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 ABRT 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 with reset board
location.
3. If the problem persists, replace the circuit pack.
2100 ABRT Could not allocate the necessary system resources to run test.
1. Retry the command at 1-minute intervals up to 5 times.
2500 ABRT 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 Packet Interface Test #598 (test
board location).
3. If Packet Interface Test #598 fails, see PKT-BUS (Packet Bus)
on
page 1790 for repair procedures.
PASS Circuit pack detects no errors.
