Replacement of a failed circuit pack is simplified by automatic provisioning of the original circuit pack values. A provisioning map for the entire shelf is stored redundantly within the SYSCTL (LNW2).
Auto provisioning is the ability of an NE to detect the presence of equipment, validate it, and then assign default original values or pre-provisioned parameter values to new equipment. Nonvolatile memory (NVM) and/or hardware registers maintain the parameter values. If you have predefined or pre-provisioned some or all of the parameters, the auto provisioning function validates the request and assigns the pre-provisioned values or default values as required. Auto-provisioning allows an NE to be set up initially with minimal user intervention. Auto-provisioning also supports a self inventory function which allows operations center personnel to learn about and track activities at a remotely located NE.
When a failed circuit pack is replaced, it is automatically provisioned with the original circuit pack values. The provisioning map for the entire shelf is stored redundantly within the SYSCTL (LNW2). It doesn't need to be uploaded from other packs. In order to replace the LNW2, remove the NVM from the old LNW2 and place it in the new LNW2. Alternatively, you may backup the database, install a factory-fresh LNW2 (with new NVM cards), enter maintenance mode, download the generic, and restore the database.
Some items that are auto-provisioned include the following:
The NE detects and reports the removal of equipment. The removal of equipment does not cause the NE to delete any entities. Removal of a piece of equipment may result in equipment alarms and insertion of maintenance signals when the state related data is updated. However, removal of equipment does not necessarily mean that the provisioning of the shelf slot has changed. The user must execute specific commands to remove an entity from the system database.
