Dell PowerEdge R730 will not power on

Hello,

I have this Dell server that refuses to power on when the power button is pressed. The iDrac is disabled so there is no other means to power on.

When the server is plugged, Only fan 4 on the server proceeds to spin. The only lights that turn on and are flashing are the "J_CTRL_PNL"(See picture below). I assume this all normal and is idling since it waiting for the unit to power on.

Does anybody know what the light flashing on and off mean ?

the two lights indicated in the arrows are flashing on and off.

Fixes i have tried so far with no luck:

  • Tried swapping the control panel
  • stripped it down to 1 CPU and 1 memory dim in location A1
  • Swapped power supplies
  • re seated everything

 

any advice appreciated,

Thank you!

Thank you Charles for the reply.

Still no luck. I get the same reaction from the server.

Looks like it is the system board that has failed. ill salvage what I can for the next server

thank you all for the help

Regards,

Jose

Hi,

 

The LED indicator has 2 diagnostics indications on it. 1 of it would be one of the hardware components connection or cable connection is not properly seated on the motherboard. The one other would be indicating that the motherboard is faulty where it can't receive enough power or circuit is burnt. Try minimum components configurations and try turning on the server, also check all the cable connections are properly seated. 

  • System board
  • One power supply unit
  • One processor (CPU) in socket CPU1
  • One memory module (DIMM) installed in socket A1
  • Left control panel (for power button functionality)
  • One backplane card

Other than these troubleshooting, I can't think of any other that could revive the server.

Hello Jose,

 

I am sorry to see that. If you have it down to the minimum to post components and have removed everything else including backplane, controller, pcie cards, network daughter card… then you may be looking at a failed system board.

 

Your diag LED's indicate:

One of the Aux power rails has failed

These are used early in the startup process (states S1 - S5) so this is likely to be a failed plug-in component or motherboard

 

Try this test to rule out control panel:

In minimum to post configuration disconnect control panel from system board. Keep the lid off of the server. Hold in the iDRAC button on the rear for 15 seconds.

Hi BladeMacho,

 

with all previous recomended steps you should be abe to solve this failure or findout which component causes the problem.

 

Did you have any further question?

 

Regards Martin

try to check if you can short the power button directly to the board.

@BladeMacho​ I just had the same problem, i found that  the front panel was the culprit, i just removed the connection to it from the motherboard and it solved the problem.
