Chapter 3 Node Setup
Viewing CTC Software Versions
When you upgrade CTC software, the XTC stores the older CTC version as the protect CTC version, and
the newer CTC release becomes the working version. You can view the software versions that are
installed on an ONS 15327 by selecting the Maintenance tab followed by the Software subtab. Select
these tabs in node view to display the software installed on one node. Select the tabs in network view to
display the software versions installed on all the network nodes.
