Chapter 1 General Troubleshooting
1.6.9 The IP Address of the Node is Unknown
ping 198.168.10.10
Step 3 If the workstation has connectivity to the ONS 15454, the ping is successful and displays a reply from
the IP address. If the workstation does not have connectivity, a “Request timed out” message appears.
Step 4 If the ping is successful, it demonstrates that an active TCP/IP connection exists. Restart CTC.
Step 5 If the ping is not successful, and the workstation connects to the ONS 15454 through a LAN, check that
the workstation’s IP address is on the same subnet as the ONS node.
Step 6 If the ping is not successful and the workstation connects directly to the ONS 15454, check that the link
light on the workstation’s NIC is illuminated.
1.6.9 The IP Address of the Node is Unknown
Symptom The IP address of the node is unknown and you are unable to login.
Possible Cause The node is not set to the default IP address.
Recommended Action Leave one TCC2/TCC2P card in the shelf. Connect a PC directly to the
remaining TCC2/TCC2P card and perform a hardware reset of the card. The TCC2/TCC2P card
transmits the IP address after the reset to enable you to capture the IP address for login. Complete
the “Retrieve Unknown Node IP Address” procedure on page 1-41.
Retrieve Unknown Node IP Address
Step 1 Connect your PC directly to the active TCC2/TCC2P card Ethernet port on the faceplate.
Step 2 Start the Sniffer application on your PC.
Step 3 Perform a hardware reset by pulling and reseating the active TCC2/TCC2P card.
Step 4 After the TCC2/TCC2P card completes resetting, it broadcasts its IP address. The Sniffer software on
your PC will capture the IP address being broadcast.
