OMSA, but you'd have racadm access if that were installed. Why can't you use racadm? What OS? The only other way is to reboot to CTRL-D/E or scan the network and hope it is on the same subnet. Default is 192.168.0.120.
It's not that I can't use racadm.. Was trying to perform in band without any dependency. Recently tried iDRAC to OS pass through, but can't seem to get that working either.
Fedora: The community releases are officially unsupported in this repository. You can, however, fake it by editing the yum config and changing "fc" to "el5". This is completely unsupported. If it breaks you can keep all the pieces.
