PS. to my earlier post regarding intrusion alarm on my PE2800::
I do not see any way to turn off the intrusion alarm setting in my system bios settings as was suggested for another system. ANY suggestions appreciated!
I had similar issue, but it was the sensor on the chassis, where the cover is supposed to be that was up. All I did was to hold it down and after about 10seconds the light stopped blinking amber. That sensor is to indicate that the server is left open/unclosed. When it is not flashing amber, it is blue and stable.
