you want to restart the system so that certificate changes can take effect, 
click OK. 
Caution 
Installing or removing certificates requires a system restart and terminates all active 
conferences. 
When you install or remove a certificate, the change is made to the certificate store 
immediately, but the system can’t implement the change until it restarts and reads 
the changed certificate store. 
For your convenience, you’re not required to restart and apply a change 
immediately. This permits you to perform multiple installs or removals before 
restarting and applying the changes. But when you’re finished making changes, you 
must select Restart to Apply Saved Changes to restart the system and finish your 
update. Before you begin, make sure there are no active conferences and you’re 
prepared to restart the system when you’re finished.
