NIC shows status no linked

Asked by jorgemop on 2019-09-02

Hi Mr Kagan, greetings from Venezuela

recently install a ubuntu 16 on an HP Proliant server with 2 network cards. all good, except that I change the configuration of the cards between static and dhcp but in no way recognize anything, the LED lights do not flash, does not turn on the light in the sw, as if they were dead, in another partition of windows the cards of Network work fine.

If a case has been presented to you before, I appreciate your guidance.

Excuse for your time, my mistake.

my lucky twisted pair cable was in bad state, eno1: <NO-CARRIER> enp2s0: <NO-CARRIER>

I'm so sorry, I apologize.
