5.1.1.3 I C Serial Bus Interface
The Vitesse VSC7161* SAS Expander supports two independent I
speed of up to 400 Kbits. The I
temperature sensor. This enables actual temperature value readings to be returned to the host.
This bus also supports an AT24C64* EEPROM or equivalent I
FRU. The Intelligent Platform Management Bus (IPMB) is supported through I
