Alarms, Errors, and Troubleshooting
Diagnostics
Check log for WRONG BOARD INSERTED errors (use list configuration all or
display circuit-packs <carrier>).
Action
Correct the ATM addresses (or swap fibers) on the A500 between the incorrectly
connected EPNs.
Swapped Routes, End System Identifiers, or Fiber
between A and B side TN230Xs on an EPN
Symptoms
The PPN establishes links to what it thinks is the active TN230X on the
EPN.
As normal, it reboots this TN230X. When complete, it resets the EPN.
When this happens, the active (instead of the standby) TN230X reboots,
dropping the links.
To recover, the PPN re-establishes links to what it thinks is the active
TN230X, and the cycle repeats indefinitely.
Diagnostics
The status pnc command on the S8700 Multi-Connect SAT shows both the A
and B side's State of Health field as partially functional.
Action
Correct the ATM addresses (or swap fibers) on the A500 between the A and B
side of the EPN.
