Thanks for all the responses especially Marek for directing me to the
correct solution from Sun.
It was an OBP setting, but not the output-device and input-device the
majority of people suggested. Even if these are set to screen and keyboard,
respectively, the server will still default to ttya for input and/or output
if they are not detected. The E450 server will boot without a monitor and
keyboard with all the default OBP and kbd settings. My problem was that the
value OBP ttya-ignore-cd had been changed from true (default) to false.
Once this was reset to true the sever boots fine with neither a monitor nor
keyboard connected even with output-device=monitor and
input-device=keyboard. Also, I am able to connect and disconnect from the
console at any point using a proper terminal emulator and cable connected to
ttya. I use the serial port on my laptop, a null modem cable, and

you. It is called "Server without a keyboard hangs in boot process".
