1-134Unusual ATM trouble conditions
1
Action
1. Correct the ATM addresses (or swap fibers) on the A5 00 between the
inco rrec tly-c onn ecte d PPN an d EPN.
Swapped Routes, End System Identifiers, or Fiber
between two EPNs
Symptoms
■All TN230Xs complete board inser tion.
■The PPN cold starts both incorrectly c onnected EPNs as usual.
■Both EPNs log many WRONG BOARD INSERTED errors (use list
configuration all or display circuit-packs
<carrier>
) providing the EPNs
actually do have different b oards configured in the same slots.
■Some end stations may work if they are connected to the correct board in
the same slot on both EPNs. Otherwise, end stations on th e PPN have dial
tone, while end stations on the EPNs do not.
■All A500 diagnostic c ommands look good .
Diagnostics
1. Check log for WRONG BOARD INSERTED errors (use list configuration all
or display circuit-packs
<carrier>
).
Action
1. Correct the ATM addresses (or swap fibers) on the A5 00 between the
incorrectly connec ted 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 comp lete, 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 ind efinitely.
