If a CP member loses connection with the rest of the cluster, the CP subsystem will wait for the 4 hours by default before connecting to a new CP member. You can configure this time in the missing-cp-member-auto-removal-seconds setting. See Configuring CP Subsystem in the Platform documentation.
You can manually remove a disconnected CP member from the CP subsystem, using Management Center.
