8.5.6 Reset Cause Sensor
This sensor is implemented to monitor the last payload reset cause, such as hard reset, front
panel reset, and so on. The IPMC evaluates the Reset Cause Register within the Glue Logic
FPGA.
8.5.7 Presence Sensors
These sensors are implemented for each SFP as well as for the cpus and the FPGAs. These
sensors provide the presence and absence status. Also, the PP #1 and PP #0 specific sensor can
assert TEMP ALERT, the FPGAs can assert CONF_ERROR.
8.5.8 Voltage and Temperature Sensors
Voltage and temperature sensors are available at the front blade and at the RTM.
Bit 1 Voltage Feed B Enabled 0: Enable B is Disabled
1: Enable B is Enabled
Bit 0 Voltage Feed A
Enabled 0: Enable A is Disabled
