Yes, sorry for causing confusion, the intent is to use the new NIC due to its speed. I just mentioned that before I was also configuring a static IP for my old NIC before I installed the new one. Both NICs are plugged in. I'm using SSH to communicate with my server, so I can tell that when I only connect an Ethernet cord to the new NIC, I cannot connect. Only when I connect a cord to the old one, I can ssh into it.
