RING UPGRADE PROCEDURE
Summary: This procedure will guide the user through a ring upgrade on the Cellworx STN
system. It is assumed that the user has gained access to the Cellworx STN system and has
launched the Graphical User Interface per NTP-016.
During this procedure, the GUI will guide the user through steps necessary to upgrade the ring
one direction at a time so it will not be service affecting. The user will be allowed to fallback to
the original level at any point during the upgrade process before it completes. Once the fallback
is initiated, the user will not be allowed to attempt the ring upgrade again until the fallback has
successfully completed. The user may fallback only to the previous ring level, and may not
convert a ring at any time to a lower ring level (i.e., OC48c to OC12c).
1. The GUI main screen, select the Ring Upgrade option by single-clicking on Configuration,
Topology, and then Ring Upgrade. The user may elect to use the shortcut key strokes of
Alt+C, Alt+T, and Alt+U. Refer to Figure 731-1.
2. The Task Overview window appears outlining each step of the upgrade process. Refer to
Figure 731-2.
3. An informational message appears instructing the user to shut down any active GUI users
on the system Refer to Figure 731-3. All GUI users should be informed of the upgrade and
log themselves off of the system during this process. Select the Next>> button.
4. The Ring Audit window appears displaying the status of the network. Fiber continuity is
mandatory before this upgrade can continue. Verify the ring continuity and rectify any
problems before continuing. Continuity can be determined by the Status column on the
bottom right of the window. Each line should indicate an “OK” status. Refer to the example
shown in Figure 731-4. Select the Next>> button at the bottom of the window to continue.
5. The Ring Upgrade Configuration window appears and allows the user to select the ring
software. Refer to Figure 731-5. If upgrading from an OC3c ring, the user must also select
the next ring configuration (OC12c or OC48c). Currently, the Cellworx STN 2.0 ring
software selection will have only one selection of 2.0.0.12. Verify the selection and left
click on the Next >> button.
