My client tells me that their server started making a noise on Wednesday and had a red critical light flashing on the front LED.
They rebooted it and the noise went away for about half a day then it returned again.
I never set this server up and inherited the support + i am working remotely and wont be onsite till next Thursday.
i can access it remotely but wanted to work out what troubleshooting steps i can do in the meantime to diagnose the issue.
Any suggestions would be very helpful as i am not sure what hardware component is failing.
I have attached a picture.
