Ping the ONS 15310-CL or ONS 15310-MA

Step1 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, or UNIX operating system, from the Common Desktop Environment
(CDE) click the Personal Application tab and click Termi nal .
Step2 For both the Sun (Solaris, UNIX) and Microsoft operating systems, at the prompt type:
ping ONS-15310-IP-address
For example:
ping 192.1.0.2
Step3 If the workstation has connectivity to the node, 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.
Step4 If the ping is successful, an active TCP/IP connection exists. Restart CTC.
Step5 If the ping is not successful and the workstation connects to the node through a LAN, check that the
workstation’s IP address is on the same subnet as the ONS 15310-CL or ONS 15310-MA.
Step6 If the ping is not successful and the workstation connects directly to the node, check that the link light
on the workstation’s NIC is illuminated.

1.9.1 Unable to Launch CTC Help After Removing Netscape

Symptom After removing Netscape and running CTC using Internet Explorer, the user is unable to launch
the CTC Help and receives an “MSIE is not the default browser” error message.
Table 1 -6 describes the potential cause of the symptom and the solution.
Table1-6 Unable to Launch CTC Help After Removing Netscape
Possible Problem Solution
Loss of association
between browser and
Help files.
When the CTC software and Netscape are installed, the Help files are
associated with Netscape by default. When you remove Netscape, the Help
files are not automatically associated with Internet Explorer as the default
browser.
Set Internet Explorer as the default browser so that CTC will associate the
Help files to the correct browser.
See the “Set Internet Explorer as the Default Browser for CTC” procedure
on page 1-52 to associate the CTC Help files to the correct browser.
