you need the drac module - sometimes it's optional, but if you can access it 
via the web
you probably have it.

you will have to:
	set the bios to allow serial over ethernet, I can't remember off heart at the 
moment.
	configure /boot/loader.conf:
		console="comconsole,vidconsole"
		comconsole_speed="38400" 	-- the speed is what you set it in the bios
	configure /boot/device.hints:
		hint.uart.0.flags="0x10"	-- or .1. depending on the bios settings

	install from ports sysutils/ipmitools
	connect the ethernet port
and finaly:
	ipmitool -A MD5 -H c <hostname.drac> -U root -I lanplus sol activate
