ATCA-7370/ATCA-7370-S Installation and Use (6806800P54F) 114
The IPMC can access the thermal information of DIMM SPD. At beginning of boot, CPU
dedicated memory I2C bus owns the DIMM SPD for memory parameter reading. IPMC can
access the DIMM SPD for DIMM thermal information through mux control signal.
