Use the Maintenance tab to perform Cisco ONS node maintenance tasks including database backups,
software upgrades, diagnostics, and other maintenance functions.
If you log into a multishelf ONS 15454, meaning two or more ONS 15454 shelves are configured to
operate as one node, the multishelf view appears in the CTC window. The Maintenance tab appears on the multishelf view (multishelf mode), node view (single-shelf mode), and shelf view (multishelf mode). Maintenance tab subtabs include:
