Temperature Sensor
There are two thermal zones on the CEC09 Carrier board that can be observed with an EMC2113
device. This device contains internal temperature sensors and can connect three external
temperature sensors. All external sensors are grouped as one thermal group and placed so that
the hottest point can be observed no matter the mounting style.
The EMC2113 device measures the temperature of several higher rated devices (I210IT/IS; RS–
232 Transceiver; 4x PCIe2UART) with the help of a common heatsink
A dual THRM LED located on the front panel indicates the current thermal.
