For ATM, an EPN can only be alarmed if it is out of service and the connections to
the PPN, ATM switch, and EPN are up. If the connection from the PPN to the ATM
switch is down (by removing it from administration, for example), all EPNs are lost
but not alarmed, since they are not the cause of the problem. As for CSS, if
connectivity is restored and the EPN fails to recover, the EPN is alarmed.
Error Log Entries and Test to Clear Values
Notes:
a. This is an informational entry only, indicating that an EPN Reset Level 1
(EPN Warm Restart) has been executed on this EPN.
b. This is an informational entry only, indicating that an EPN Reset Level 2
(EPN Cold Restart) has been executed on this EPN. This does not include
restarts done at system initialization time.
c. Indicates that an EPN is not in-service when it is expected to be. The value
specified in the port field of the error log, is the PN number of the affected
PN. When this condition occurs, examine all system link errors and
EXP-INTF or ATM-PNC errors to aid in resolving the alarm (examples of
system link errors are errors logged against PKT-INTF, EXP-INTF, SNI-BD,
FIBER-LK, and PKT-BUS and for ATM, PKT-BUS, ATM-EI, ATM-NTWK).
Also check that all fiber connectivity matches that which has been
administered for the system. This alarm and error is resolved and removed
from the logs only when the EPN comes back into service, or after fiber
administration is changed to remove a fiber such that there is no
connectivity from the PPN to this EPN.
d. This alarm is raised when EPN maintenance has attempted to execute a
Cold Restart recovery action two times, and both restarts failed. This will
cause the EPN to be placed in Emergency Transfer. Examine all EXP-INTF
or ATM-EI errors which, when cleared, may aid in resolving this alarm. Also
check for any SNI-BD, SNI-PEER, FIBR-LK, SN-CONF, or DS1 CONV-BD
errors or for ATM, ATM-EI or ATM-NTWK errors that may indicate a
communication problem between the processor and the EPN. Make sure
that the physical fiber connectivity matches that of system administration.
