The easiest thing to do would be to log into the iDRAC and check the SEL, if you can. If the iDRAC isn't an option, then the next tool you could use to check would be OpenManage Server Administrator. You can install that and then view the system log. OMSA 9.3: [URL]
Hello, it's me again with a question,   We have a Dell PowerEdge R510 running as a NAS server. it's running Windows Server 2016. We noticed there is a red light blinking under the power button. I know there is something wrong with it, I just can't figure out what. All disks in it are giving me green lights. the Power modules also have green lights. How can I find out what is wrong with this server?   Thanks in advance,   Kind regards,   Bjorn
