RB450G no link on ports 3-5

RouterOS Beginner Basics
1

I hope I’m just doing something stupid here. I just got my first routeros product, an rb450g, and set it up according to the initial configuration guide here. Everything is working, I have internet access, can ping, etc.

the problem is, the ports 3, 4, and 5 don’t work. No link lights, no activity or negotiation status under interfaces, nothing…
have tried different devices, different cables, rebooting, and resetting.
port 2 works fine, gigabit negotiated
port 1 is wlan, works fine

Do I have a bad board, or am i just doing something wrong? Is there an option to turn off ethernet ports in the configuration? I know it says that ports 3-5 are slaved to port 2, but I believe that just has to do with switching?

At a total loss here, was excited about getting a powerful product fairly inexpensively, but looking through the forums, wow, lots of hardware problems.

Can you provide an “/interface export” to let us know how your interfaces are configured?

Hope this helps…

If you look at your configuration you have not specified the master port even though you have labeled them as slaves.
