Troubleshooting
Troubleshooting ATM
Action
Correct the ATM addresses (or swap fibers) on the A500 between the incorrectly connected PPN and PN.
Swapped Routes, End System Identifiers,
or Fiber between two PNs
Symptoms
• Every TN230X completes board insertion.
• The PPN cold starts both incorrectly connected PNs as usual.
• Both PNs log many WRONG BOARD INSERTED errors (use list configuration all or display
circuit-packs carrier), provided the PNs actually do have different boards configured in the same
slots.
• Some end stations may work if they are connected to the correct board in the same slot on both
PNs. Otherwise, the PPN's end stations have dial tone, while the PN's end stations do not.
• Every A500 diagnostic command looks good.
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 PNs.
Swapped Routes, End System Identifiers, or
Fiber between A- and B-side TN230Xs in a PN
Symptoms
• The PPN establishes links to what it thinks is the active TN230X in the PN.
• As normal, it reboots this TN230X. When complete, it resets the PN. 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
Action
Correct the ATM addresses (or swap fibers) on the A500 between the A and B side of the PN.
