Mellanox MT27500 Link para a Porta 1 está Inativo

Question

Tenho a placa de duas portas Mellanox MT27500 instalada no HP SL250s. O Ubuntu 14.04.5 com o kernel 3.13.0-24-generic está sendo executado no servidor. O tipo port1 e o tipo port 2 são definidos como eth. Eu conectei a porta 1 e a porta 2 para alternar com o mesmo tipo de cabo, mas somente a porta 2 parece estar vinculada. Led pertence à porta 1 está desativado.

Você tem alguma ideia de usar as duas portas?
