To Open the Menu in Shelf View:
Right-click anywhere on the blank (white or gray) space in the Shelf View (outside of the card slots).
This should bring up a context menu with options like:
Provisioning
Inventory
Maintenance
View
Alarms
If right-click doesnāt work, try:
Clicking the top menu bar, depending on your CTC version (older versions sometimes auto-hide or collapse this).
Use the dropdown in the upper-right corner (or upper-left on older versions):
Look for a dropdown selector with options like:
Network View
Node View
Shelf View
Switch to Node View or Network View, which often brings back the full menu.
