Both EC1 and EC2 are connected as RGMII. We have connected EC1 to one PHY and EC2 to Switch. Can we use either EMI1/EMI2 alone (single management Interface) for both EC1 and EC2?

Suppose if we use both Management interface EMI1 and EMI2, shall we connect any of the management interface EMI to either of EC1 or EC2? is there any restriction that EC1 should be connected with EMI1 & EC2 with EMI2?

Any PHY in the system can be connected to any externally visible
management interface, regardless of the data path connection.
EMI1 and EMI2, however, are not identical. Their pin drivers are
fed from different power supplies and only EMI2 supports IEEE802.3 Clause 45
extensions. See LS1043A Datasheet, Section 3.11.6 for details.


Have a great day,
