This read-write integer (0-100) sets the floor value for temperature sensor 2, and a reading below it puts cpqCmcStatusTemp2 into underMin(5). It helps an administrator detect an implausibly cold reading from the second sensor, which usually points to a disconnected sensor or a cabinet door left open to a cold aisle. Setting this to 35 degrees, for instance, would flag a sensor-2 reading that dropped because a technician left the rear door open during maintenance.
