2. For both the Sun and Microsoft operating systems, at the prompt enter: ping IP-address
3. If the workstation has connectivity to the NCS, 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.
4. If the ping is successful, it demonstrates that an active TCP/IP connection exists. Restart CTC.
5. If the ping is not successful, and the workstation connects to the NCS through a LAN, check that the
workstation IP address is on the same subnet as the ONS node.
6. If the ping is not successful and the workstation connects directly to the NCS, check that the link light on
the workstation NIC is illuminated.
DETAILED STEPS
Step 1 Display the command prompt:
a) If you are using a Microsoft Windows operating system, from the Start Menu choose Run, enter command 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 enter: ping IP-address
For example:
ping 198.168.10.10
Step 3 If the workstation has connectivity to the NCS, 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 NCS through a LAN, check that the workstation 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 NCS, check that the link light on the workstation
NIC is illuminated.
The IP Address of the Node is Unknown
Problem 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.
Solution Leave one control card in the shelf. Connect a PC directly to the remaining control card and perform
a hardware reset of the card. The control 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, on page 46.
Retrieve Unknown Node IP Address
SUMMARY STEPS
1. Connect your PC directly to the active control card Ethernet port on the faceplate.
2. Start the Sniffer application on your PC.
3. Perform a hardware reset by pulling and reseating the active control card.
