555-233-143
4-60 Issue 1 May 2002
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.
