Hi friend, The ports in the first row of this product are named after 2 4 6 8 (even-numbered) ports. Also, I want to clarify. The preceding 28 ports are optical ports, which determine the port rate based on the rate of the inserted optical module. For example, if you plug in a 25g module, the port rate will also be written as 25g. The latter four ports support 40g and 100g rates.You can refer to the link below for pictures of this product.
