Maintenance for csi systems
1-134Unusual ATM trouble conditions
1
Action
1. Correct the ATM addresses (or swap fibers) on the A500 between the
incorrectly-connected PPN and EPN.
Swapped Routes, End System Identifiers, or Fiber
between two EPNs
Symptoms
■ All TN230Xs complete board insertion.
■ The PPN cold starts both incorrectly connected EPNs as usual.
■ Both EPNs log many
WRONG BOARD INSERTED
errors (use
list
configuration al
l or
display circuit-packs
<carrier>
) providing the EPNs
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 EPNs. Otherwise, end stations on the PPN have dial
tone, while end stations on the EPNs do not.
■ All A500 diagnostic commands look good.
Diagnostics
1. Check log for
WRONG BOARD INSERTED
errors (use
list configuration al
l
or
display circuit-packs
<carrier>
).
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.
