Each fan tray can survive up to two individual fan failures. The failure of a single fan causes a minor alarm
to be issued. Two or more alarms result in a critical alarm. The fan tray should never be removed from and
operating system for more than 5 minutes or damage may occur to the CCTs and/or PLMs.
