The IPMI from SuperMicro has a web interface where you can do user maintenance for ipmi, remote control of hosts, record video(for recording other people's access to this system i guess), from there you can set Serial over Lan options. Here is the base screenshot

It does use java for some things still. There are also functions here i have no clue what they are. No idea what RAKP Protocol Setting is, but it is there.
Here is a nice feature, it shows how much power your host is using. It changes every few seconds.
