Don't forget to change IPMI PW!Okay if it requires DHCP this might be out, I'm currently out of town watching my brothers (various disabilities) while parents are on much needed vacation. Don't have easy physical access to the router, would have to take out stuff in front of it.

But from your laptop you can run a DHCP server which would then assign an IP to the IPMI interface. The IPMI might self-assign if it can't find a DHCP server, but in my memory (which might be faulty) it doesn't do this. If for some reason Java doesn't work from your browser, Supermicro also distributes a Java GUI tool for interacting with Supermicro IPMI interfaces. It also supports a subnet scanner, so you don't need to know the IP that gets assigned. Look for IPMIview here: http://www.supermicro.com/products/nfo/IPMI.cfm It's not a great tool but it works well enough for console access. --keith -- kkeller at wombat.san-francisco.ca.us

Might be of use to some here: https://alteeve.ca/w/AN!Cluster_Tutorial_2#What_is_IPMI -- Digimer Papers and Projects: https://alteeve.ca/w/ What if the cure for cancer is trapped in the mind of a person without access to education?

I don't yet know if the video card is bad or the board just can't use it, I'll find that out later. But for now via VGA cable it is all working. For what's worth, removing both flash and java capabilities from my browser was the second best thing I ever did (privacy badger the best), don't want to re-install either. Once I'm back home and this server is set up where it goes, I'll try playing with non-browser IPMI tools and see what it is all about.
Is there a little setup display right on the box? Just asking because I have seen that on some boxes. Cheers, Boris.
