It is accessed over lan, you need a server with "IPMI over LAN" like 
Integrated Lights-Out from HP, most known as iLo ( 
http://h18013.www1.hp.com/products/servers/management/ilo/ ). iLo has a 
network port that you can use to control a server remotely.

I think a good way (if the server are near...) could be use a cross-over 
ethernet wire.
