Dell R920 cant boot.

Hello everyone again, so i have R920 server, i have 4CPU's, 8 Memory cards (but use only 4 for example) and the problem is server cant boot.

At first on display appears "Configuring Memory..." after one minute appears "...Done"
Screen gets black and the PSU fans stop rotating. VGA-signal gets lost with no error message.
Only LEDs on board keeps blinking. So I can't enter bios or iDrac.

Anyone can tell me what can be the problem?

Nevermind i got it. I didn't think about jumpers at all, it turns out that the jumpers were misplaced. Once set up correctly, everything works as it should.

I had relied on your original posting, found here, in which I had stated;

 

I would start with taking the R920 to its Mimimum to Post configuration, which is removing everything internally and externally from the server but the following;

 

  • One Power Supply
  • One Power Supply Distribution Baord
  • One System Board
  • One Processor (CPU) in socket CPU1 (minimum for troubleshooting)
  • One Memory Riser
  • One Memory Module (DIMM)
  • One Network Daughter Card

 

After that then try powering up, if the server completes post then individually add the removed devices back until the issue reapears, which identifies the device causing the issue. 

 

Let me know what you see.
