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.
