Ethernet-порты Solaris: отсутствуют nge2 и nge3

Есть Sun X4100 с интерфейсом nge0 который настроен и работает. Сервер имеет группу из 4 сетевых разъемов сзади и nge0 соответствует порту Ethernet 0.

Я попытался включить порт Ethernet 3 с помощью ifconfig nge3 plumb и я получил вывод

ifconfig: plumb: nge3: Invalid argument

Но я могу настроить nge1 без проблем.

Вот результат prtconf -D

Есть идеи, как настроить порт 3?
