The CMA system requires a CRL for each CA or sub-CA in the certificate 
chain. The CMA system also requires that you upload a new CRL at regular 
intervals. This interval can be as short as a few days in higher security 
environments or a few months in environments with lower security 
requirements.
To upload a certificate revocation list 
1
Go to Admin > Management and Security > Certificate Management 
and click Upload Certificate Revocation List
2
In the Select file dialog box, browse to the location of the CRL that you 
obtained from the CA and select the file.
3
Click Open.
Delete a Certificate 
You can delete certificates from the CMA system, but the CMA system 
prevents you from deleting any certificate that breaks the identity certificate’s 
chain of trust. To delete these certificates, new CA certificates must be installed 
and the identity certificate must be replaced.
To delete a certificate 
1
Admin > Management and Security > Certificate Management
The Certificate Management page displays the list of currently available 
certificates. 
2
Select the certificate to be deleted and click Delete Certificate
A warning appears stating that changes made to the certificates will 
require a system restart to take effect. 
3
Click Yes to continue.
IMPORTANT
If an administrator does not upload a new CRL by the CRL Next Update date, the 
system will become unresponsive. Recovering from this situation requires 
reinstalling from the recovery disk, manually reconfiguring of identity and root 
certificates, and restoring the system from a system backup
Caution 
Removing certificates requires a system restart, which terminates all active 
conferences. 
When you 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.
