Note
Ciscomaintains a set of best practices for managing firmware images and updates in this document and in
thefollowing technicalnote: Unified Computing SystemFirmware Management Best Practices.
Thisdocument uses thefollowing definitions for managingfirmware:
Upgrade
Changesthe firmware running on an endpoint to another image, such as a release or patch. Upgrade
includesboth update andactivation.
Update
Copiesthe firmware image to the backup partition on an endpoint.
Activate
Setsthe firmware in the backup partition as the active firmware version on the endpoint. Activation
canrequire or cause the reboot of an endpoint.
ForManagement Extensions and Capability Catalog upgrades, update and activate occur simultaneously. You
onlyneed to update or activate those upgrades. You do not need to perform both steps.
