Emergency CRL (Certificate Revocation List) Update

Administrators maintaining RMX systems are required to perform an update of the CRLs used on the systems within the validity period of the current CRLs.

Should the current CRLs expire; the system will not allow administrators to login and perform administrative tasks using the RMX Web Client or RMX Manager.

The Emergency CRL Update procedure disables client certificate validation enabling an administrator to access the system and install an updated CRL file without having to perform a full system rebuild.

This procedure must only be performed on a secured network as the system must disable the client certificate validation process resulting in management traffic being sent over the network without the use of SSL encryption.

The RMX must be powered on before starting this procedure.

To perform an Emergency CRL Update procedure:

Step 1: Download and save the updated CRL files from the CA Server.

Step 2: Disable Secured Communications Mode.

Step 3: Open the Certification Repository and update the CRL files.

Step 5: Update the Repository.

Step 6: Re-connect to the RMX.

Step 7: Re-enableSecured Communications Mode.

Step 1: Download and save the updated CRL files from the CA Server

These files are saved on the workstation.

The RMX supports the use of PEM and DER formats.

Take note of the format you download as you will need to make a selection later in this process when uploading the new CRL files.
