Additional Devices

6.2.1

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

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.
