I found the hard drive went bad also on the mother board I had "green caps" the mother board falls under a bulletin. I hooked up a monitor to the 400 and rebooted. The monitor showed the "Nortel" sign with a loading bar at the bottom of the screen. The loading bar would shoot across the screen then the screen would go black. The "Nortel" sign and load bar would come back and the same would happen a few times and then I got the "Nortel" and load bar; the load bar went to about 80% and stopped it sat there for about 10-15 min. It might have saved time had I known what all the LEDs on the front meant and about the monitor port behind the cover.
Thanks for the input.
