locked out!

:confused:
I have an K580 HP server.
All I did was change the IP address on the NIC and now I can't telnet into it.
I can ping, but no telnet.
Also, it won't boot if the console monitor is plugged in.

ANY IDEAS???

I'm good to go.
Did the Ctrl+D on the console, then ./inetd

We're up and running now.
