I've used both remote KVM and SOL, and both work very well.  Your board
must have an active BMC for this to work; as John mentioned, it's not a
default feature (though it's becoming more so on ''server-class''

The remote KVM is a Java Web Start applet.  I've had some issues getting
it to work, especially on an OS X client.  A CentOS client is usually
okay but sometimes flaky.  Serial-over-LAN is more convenient to access
but less well documented (which says something, since Supermicro's docs
on their IPMI implementation are generally quite poor).

And +2billion on securing the subnets used to access to the IPMI consoles.
