6.7 Temperature Monitoring
Temperatures are reported to the user in degrees Celsius (°C) and degrees
Fahrenheit (°F).
6.7.1 Host Card Monitoring
The die temperature of the main components on the Host card are monitored, and
reported to an accuracy of ±2 °C.
A host card temperature alarm threshold can be set that, if exceeded, causes a
System Over Temperature Alarm to be generated.
6.7.2 Transcoder Module Monitoring
Transcoder modules monitor the die temperature of their main components, and
report these temperatures to an accuracy of ±2 °C. If a transcoder module reports
die temperatures, it allows an alarm threshold to be defined for each temperature,
which if exceeded causes an alarm to be generated.
6.7.2.1 Media Processing Modules
The controlling processo
r monitors the core temperatures of the main components
and passes this information back to the host card via the back plane for monitoring.
Temperature thresholds can be set to cause a warning or an alarm. The warning
level is configurable by the user, whereas the alarm level is hard coded.
