Additional Troubleshooting for EUCN nodes
EHP
M Node not coming to “ALIVE” state
If an EHPM is not coming into the “ALIVE” state on the UCN Status Display, and it shows OFFNET, it
could mean that the ENIM has not authenticated that EHPM. To resolve this problem:
1. Check that the UCN Node Configuration for the ENIMs and EHPMs are checkpointed to the
ENIMs, and that the ENIMs are freshly re-booted and re-loaded with this checkpoint.
2. Check the UCN Node Configuration for the EHPM as to whether it is configured in the same ENIM
network or not.
3. Power cycle the EHPM to see if it helps to resolve the issue.
4. Verify that the same EHPM is not configured in any other ENIM or any other Authentication Group
in the same LCN.
Authentication Group showing Zero (0) from the $FTESTS2 display
If the $FTESTS2 Display details for a specific EUCN node (shown when an individual FTE status line is
selected), shows an Authentication Group of “0” for any of the EUCN nodes, it could mean that the node
is not authenticated by the ENIM. To resolve this problem:
1. Check that the UCN Node Configuration for the ENIMs and EHPMs are checkpointed to the
ENIMs, and that the ENIMs are freshly re-booted and re-loaded with this checkpoint.
2. Check the UCN Node Configuration for the EHPM as to whether it is configured in same ENIM
network or not.
3. Power cycle the EHPM to see if it helps to resolve the issue.
4. Verify that the same EHPM is not configured in any other ENIM or any other Authentication Group
in the same LCN.
5. Finally, check your switch configuration settings to make sure all nodes are properly configured at
the switch level.
