2500 ABORT Internal system error
1. Retry the command at 1-minute intervals, a maximum of 5
times.
NO
BOARD
The Packet Interface is not detected as being physically
present.
1. Reboot the system, then retry the command. If the NO
BOARD indication persists, replace the TN2401/TN794
NetPkt circuit pack.
1-3 FAIL The test failed. Maintenance was unable to establish a
looparound link from the Packet Interface back to itself or was
unable to receive data that was sent out over one side of the
looparound link.
1. Issue the test packet-interface CS command to retry the
test. If the same error code is observed, background
maintenance software will automatically attempt to reset the
circuit pack and clear the problem.
2. Retry the command and if the test fails, replace the
TN2401/TN794 NetPkt circuit pack.
3. If the test continues to fail after replacing the
TN2401/TN794 NetPkt circuit pack, run the test packet P
long command. If any of the tests fail, the fault may be on
the Packet Bus. Refer to the PKT-BUS (Packet Bus)
Maintenance documentation for recommended repair
procedures.
4. If the test continues to fail after the TN2401/TN794 NetPkt
circuit pack is replaced and with no other alarms associated
with the Packet Bus or circuit packs connected to the
Packet Bus, follow normal escalation procedures.
PASS This test passed. The Packet Interface and its interface with the
SPE are functioning properly. If the system is unable to place
calls on cabinets other than the SPE cabinet, then:
1. Check for errors on the Packet Bus and Maintenance/Test
circuit pack. Solve those errors first.
2. Check all other circuit packs connected to the Packet Bus in
the same cabinet. Packet Bus failures are likely to be
caused by a faulty circuit pack connected to the backplane
or bent pins on the back plane.
3. Check the TN2401/TN794 NetPkt circuit pack connections
to the Packet Bus.
