Under many different names (Sun called it LOM; I forgot IBM's
name), this has been out there for a while. And it is IMHO the best
way to deal with servers. My normal server installing procedure is:
1. slap server wherever it will reside
2. Run the power cords
3. Run the ethernet cords for both normal use and IPMI. I'd probably
be mindful of which vlans each cable goes to.
4. Fire computer up
5. Connect to the IPMI ethernet port using openipmi/whatever; by
default it is generally setup to do dhcp.
6. Through ipmi, configure server's bios/raid/whatever and then boot
it, feeding an ISO with the OS of choice through ipmi. Good time to do
any server bios upgrade too.
7. Don't forget to change IPMI PW!

Connect both to a switch attached to your dhcp server (or make
laptop provide that to ipmi) and then connect from laptop to ipmi and
go do your thing.
Video cards are for desktops.

Personally I do not think the supermicro box cares. IPMI is a
standard. Whichever you use should provide a way to send out (remote)
commands and then have a console so you can install thingies in the
With that said, I have used openipmi myself; you do want the ipmitool,
which is a package.
Sample commands (lookup to see what they do. Notice I am using default l/p):
ipmitool -I lan -H 192.168.21.125 -U ADMIN -P ADMIN sel
ipmitool -I lanplus -H 192.168.21.125 -U ADMIN -P ADMIN mc reset cold
ipmitool -I lanplus -H 192.168.21.112 -U ADMIN -P ADMIN mc info
