They are AFAIK. I think the breakthru with the T1s and similar age  
servers were they were some of Sun's first with *on board* lights-out  
management built into the actual server, not reliant on a separate  
card. I think even with the primitive serial LOM on these you would  
have been able to fit an add-on management card in addition. Our  
Poweredge 1800 at $work is like this - it has a serial-only BMC  
controller built onto he board, which at the very least allows you  
limited power control and primitive fault diagnostic, and we had a  
DRAC remote access card fitted which allows full authenticated desktop  
access over LAN/VPN as well as Power Cycling and independent SNMP  
monitoring of the machine itself. From reading Sun's description of  
RSC it is very similar, right down to the Java console, although I  
think maybe RSC has no graphical access (you only need that crap in  
Windows Server because it's impotent and has no decent terminal!).

Modern servers like the Fire Txx00 and Xxx00 series have a lot of the  
required remote managment jazz built onto the actual mainboard. It's  
all on it's own LAN port on most of them I think now so you can plug  
them all onto a switch and use SSH or terminal each one by a  
management IP. It must really eat up your IP pools on a large network,  
I have a vision of a subnet for management IPs, and one for the actual  
servers, with a U20 with twin NICs setup with one NIC on each. Oh how  
I'd love an enterprise network room to play with ;)
