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. For more
information, refer to the section

NVSRAM
The RXi2-UP IPC offers Non-Volatile Random Access Memory (NVSRAM) as a mPCIe board
add-on option that is automatically backed up when the RXi2-UP IPC is switched off or loses
power. It is not supplied with battery power but an exhausted Lithium coin battery will not
result in a loss of data. Contact Emerson for assistance with the option.
