MPM+ Card Properties

The MPM+ and CPU (CTRL) cards have the same concept and shown in
Figure , "" MPM+ card.

The hottest sensor on the MPM+80 card is sensor 16, and when this sensor
reaches 70 (degrees) Centigrade, it triggers an "Upper Major" event.
°
The "Upper Major" event causes the RMX fans to increase their RPM
rotation by circulating more air. If the Temperature sensors then reach
"Upper Critical" then the Shelf Manager initiates a shutdown on the over-
heated MPM+ card.
The following table lists the temperature thresholds that can activate
alarms and are an indication of the MCU's state. On an MCU there are a
number of temperature sensors that will activate when their thresholds
are reached.
