Chapter 1 General Troubleshooting
1.9.8 Verify PC Connection to the ONS 15454 SDH (ping)
Possible Cause The NIC is faulty.
Recommended Action Confirm that the NIC is working properly. If you have no issues connecting to
the network (or any other node), then the NIC should be working correctly. If you have difficulty
connecting to the network (or any other node), then the NIC might be faulty and needs to be
replaced.
1.9.8 Verify PC Connection to the ONS 15454 SDH (ping)
Symptom The TCP/IP connection was established and then lost, and a DISCONNECTED transient alarm
appears on CTC.
Possible Cause A lost connection between the PC and the ONS 15454 SDH.
Recommended Action Use a standard ping command to verify the TCP/IP connection between the PC
and the ONS 15454 SDH TCC2/TCC2P card. A ping command will work if the PC connects directly
to the TCC2/TCC2P card or uses a LAN to access the TCC2/TCC2P card. See the “Ping the
ONS 15454 SDH” procedure on page 1-118.
Ping the ONS 15454 SDH
Step 1 Open the command prompt:
a. If you are using a Microsoft Windows operating system, from the Start Menu choose Run, type
command prompt in the Open field of the Run dialog box, and click OK.
b. If you are using a Sun Solaris operating system, from the Common Desktop Environment (CDE)
click the Personal Application tab and click Terminal.
Step 2 For both the Sun and Microsoft operating systems, at the prompt type:
ping ONS-15454-SDH-IP-address
For example:
ping 192.1.0.2
Step 3 If the workstation has connectivity to the ONS 15454 SDH, the ping is successful and shows 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, an active TCP/IP connection exists. Restart CTC.
Step 5 If the ping is not successful, and the workstation connects to the ONS 15454 SDH 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 SDH, check that
the link light on the workstation’s NIC is illuminated.
