2.9 I2C

The T2080 devices supports up to four I2C buses, in order to make the I2C resources
equally available to both local and remote systems. The T2080RDB-PC uses I2C1 port to
access onboard devices, such as DDR3 DIMM, RTC, I2C EEPROM, clock generator,
thermal sensor (ADT7481), and core power regulator (IR36021). The I2C2 bus uses
multiplexers to partition the I2C bus into several sub-buses, called channels. Two SFP+
optics use channel 0-1 and the PCIe SLOT use channel 3.

The image below shows the I2C subsystem.
