Unusual ATM trouble conditions
Action
1. 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, and 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
1. The status pnc command on the DEFINITY SAT shows both the A-side
and B-side State of Health field as partially functional.
Action
1. Correct the ATM addresses (or swap fibers) on the A500 between the A
and B side of the EPN.
