MPM+ Card Properties

The MPM+ and CPU (CTRL) cards have the same concept as for the RTM IP and is shown in
Figure 20-8.

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.
