1 FAIL The Private Link Broadcast Loop-Around test failed. The circuit pack will enter
a fatal fault state when this occurs and the Packet Interface maintenance
software should put the circuit in a out-of-service state. Therefore by the time
further action is taken, it is expected that the test will abort with ABORT code
1137 and a demand reset should be used to test the circuit pack.
1. Reset the circuit pack using the reset packet-interface Uc command.
For further action, see the repair procedures in Table 8-394 on page 8-938
for the Packet Interface Reset test (#889).
2. If the test continues to fail, replace the IPSI circuit pack.
2 FAIL The Private Level-2 Loop-Around test failed. When this occurs, the circuit pack
enters a fatal fault state, and the Packet Interface maintenance software should
put the circuit out of service. Therefore, by the time further action is taken, the
test should abort with ABORT code 1137, and a demand reset should be used
to test the circuit pack.
1. Enter reset packet-interface Uc to reset the Packet Interface circuit.
For further action, see the repair procedures in Table 8-394 on page 8-938
for the Packet Interface Reset test (#889).
2. If the test continues to fail, replace the IPSI circuit pack.
PASS Every private loop-around test passed. The circuit pack is functioning properly.
If the system is still unable to place calls on cabinets other than the server
cabinet, then:
1. Display the error log using the command display errors, and check for
errors on the packet bus and Maintenance/Test circuit pack. Clear 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. See
‘‘PKT-BUS (Packet Bus)’’ on page 8-918 the PKT-BUS for repair
procedures.
