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.

NVSRAM
The RXi2-EP IPC is capable of Non-Volatile Random Access Memory
(NVSRAM) as a mPCIe board add-in option that is automatically backed
up when the RXi2-EP IPC is switched off or loses power. NVSRAM does not
use or require a battery. Contact Emerson for assistance in accessing
NVSRAM.
