Poweredge 1800 power suply alarm orange

SOURCE: dell server poweredge 1800 frequently shutdown

is there an error message that appears? can you check error logs? I need more information to be able to help you. I would first try to blow dust out of the fans, as it may be over heating, another possibility is that there is software on the machine that is causing it to shut down.

During the Windows XP setup you will need to provide the RAID driver using a pre-formated floppy disk.
Windows will ask you if you want to provide additional drivers and give you the key combination to use to do that.

Hi,
check if the drive is showing in the bios of the server,
shut down the server, take out the power cable, press and hold the power button so as to realease flea power, open the server, and reseat the data cable at both ends and if there is another power cable available in the server swap it with the existing cable plugged into the scsi drive.

and now try to start your server.
Further Queries are welcome

dells power supplies must come from dell. I would call dell and give then the service tag number of your server and they will be able to tell you about how much a power supply is.
