I have a S1200BTPL that is giving me fits.. If I turn it off completely then start it it starts OK. If I do a restart from withing SBS2011, then it shuts down, does the beep codes.. but then hangs.
If I go in under remote management BMC and do a power cycle it starts up. or if I power it off and then start it again, it starts up. It is just an issue restarting it..
Maybe SBS is doing something funky with the ACPI restart?
I don't suppose you know if 2003 or Windows 7 does the same thing; do you?
What is the beep sequence that it gives you? 1-5-4-4?
