Hey everyone, Grabbed a 2009 Xserve to tinker with, it won’t show anything on screen, the CPU doesn’t get warm, the PSU fans are the only fans that are on. All the LEDs on the edge of the second expansion slot are green, the CPUA MEM LED is lit up green, the System State is reported as S0 by a green LED, and the PLT_RST is orange. The orange status LED blinks, then off, then more blinking
I can answer any questions needed, I’ve already reseated the CPU and RAM. Any help would be greatly appreciated!
At this point you need to trace out the power rails to see where the failure is. I have not found the schematics or boardview for the xServe units. Apple had a great system but failed to get the market to grab it. This is also the same problem Apple faced with the original HomePod great speaker just to costly and limited for what people wanted. I would search out for the Xserve (Early 2009) Apple Technicians Guide copies are out in the wild it could offer you deeper information on the diagnostic LED’s as well as the boot process. This system is a bit different than a Mac as you only have a terminal session directly.
