This section explains CPU replacement considerations and how the chassis SSD helps preserve software and configuration during disaster recovery operations.
CPU replacement considerations is a Cisco NCS 1010 feature or capability that
-
supports the related system setup or management workflow,
-
defines behavior that affects Cisco NCS 1010 operation, and
-
provides context before you configure or verify the feature.
CPU replacement considerations details
You must consider the following points for CPU replacement.
-
When the CPU is removed from the chassis, NCS 1010 chassis runs in headless mode which is non-traffic impacting.
-
When the CPU is replaced with another CPU having the same software and RPMs as in the chassis SSD, the configuration is restored from the chassis SSD.
-
When the CPU is replaced with another CPU having different software and RPMs as in the chassis SSD, the Disaster recovery process starts. In this case, the node boots with the software from the chassis SSD and the configuration is also restored from the chassis SSD.
