to perform plugin lifecycle-related actions (install/uninstall/
enable/disable)?

the job is initiated in the back-end but you still see the Console and Plugins page. And, the following message is displayed after

Power cap value or the percentage for MX 7000 chassis is
not updated when either one of the entries is changed

groups.
