5.2.3.2
Temperature Sensor
The 6HDD SATA/SAS HSBP provides a National* LM75 or equivalent temperature sensor.
The
host can query the LM75 at any time to read the temperature.
The temperature sensor has an I
2
C address of 0x90h on the GEM424 controller Port 0.
5.2.3.3
Serial EEPROM
The 6HDD SATA/SAS HSBP provides an Atmel* 24C02 or equivalent serial EEPROM for
storing FRU information.
The 24C02 provides 2048 bits of serial electrically erasable and
programmable read-only memory.
The serial EEPROM has an I
2
C address of 0xA6h on the GEM424 controller Port 1.
