I'm going to install a Cisco 2911 Router along with a 3560 switch for a customer in about two weeks. Even though I'm a CCNA, I've never touched any Cisco equipment in my life. I have some experience with HP networking gear, but that's it. I was hesitant about doing it but I figured why not try? So I ordered a couple of routers and switches to practice in my home.
What should I pay attention to? What issues may arise while I'm on site?
P.S. Please move the topic if it's not in the right section
