AS7326-56X - How to identify whether the hardware version supports RJ-45 copper transceivers? Follow

Purpose : 

This article shows how to identify whether the AS7326-56X hardware version supports RJ-45 copper transceivers or not.

RJ-45 transceivers are supported with H/W version R01G or newer.

Model : 

AS7326-56X

Description: 

Users can check the hardware version (label revision) from the system EEPROM, the R01G (or above) supports RJ-45 copper transceiver.

Further Explanation:

Since the most of RJ-45 transceiver PHY IC can be accessed via I2C bus at address ACh (0x56). But the system EEPROM of the old hardware version is at the same I2C address, therefore, it has an address conflict in this condition. It is possible to cause the transceiver not to work properly.
