Was configuring some Dell 2824 switches which are pretty good switches for the money. However I ran into some issues.
The command line over the serial connection didn't allow me to set the IP or anything so I did a quick Google and came across this article.
In there I found that the 28xx series switches use a default IP of 192.168.2.1. I browsed there and was able to login with admin and no password. This allowed me to fully set them up.
I hope that this helps somebody else too.
