All,   I replaced both power supplies and the server is running with no issue. I guess when the one power supply blew out, it also caused some type of damage to the other. I was hearing a high pitch squeal in the working one. After I replaced both I tried to also boot with one of the two and it continued to work. With voltage sometimes redundancy doesn't work I guess. In any case I've saved a server.
Hi All, At bit of a background on this server. It had a blown PSU after which the server would not boot. I pulled it from our data center to troubleshoot it and it's a bit of a strange one. The server starts up and posts with the working PSU but after it gets to the iDrac and finishes posting it reboots. I took out CPU 2 and had just one memory module with CPU 1 and the server posts and goes into the BIOS. I then took CPU2 and put it into the CPU1 socket and the server boots and gets into the BIOS. It's only having issues when both CPUs are in there. I suspect there may be an issue with the other PSU even though the server is booting. I'm going to try to get two good PSUs from another 720xd and see if the issue goes away to rule out the MB as the issue. If the issue persists with two other PSUs, would the issue then be with the MB?   Thanks
R720xd posts but reboots
