DELL R910 - E1234 Memory Riser G Power Failure

Hi,

We have a DELL R910 server (Service Tag:<ADMIN NOTE: Service tag removed per privacy policy>) and have read some articles here about the problem "E1234 Memory Riser Power Failure" .  We have done some of the suggested troubleshooting.  On our system, here's what we've done so far:

1.  Reseat the Memory Riser G and its DIMMs.  Same problem encountered.

2,  Cleaned the Slot and contacts of the riser for any dusts or dirt.  Same problem encountered.

3.  Swapped Memory Riser from  C with that of from G slot.  Same problem encountered (the problem is still on Memory Riser G slot)

4.  Removed the Memory Riser from slot G so there's no Memory Riser installed on slot G.  Same problem encountered (the problem is still on Memory Riser G slot)

So it seems that slot G on the System board unit have a problem.  I haven't replaced the system board unit yet (will be waiting for replacement).  Is there any other way to make this server boot up as we need this one badly.  Can we just disable slot G and place the Memory Riser on the other slot allocated to that CPU? (Note: we have 4 CPUs, so we have 2 slots of Memory Risers per CPU)

Regards,

Paolo

    Paw0702,

    Did the error happen to start during a power up or while it was running normally? If it did it on power up then we can try the following procedure to clear the issue.

    1.       Power off the system if it is not already powered off


    2.       Remove AC cord, wait for standby voltage to dissipate (10-20 secs or no LEDs visible and no LCD illumination)

    3.       Remove the G memory riser identified by the E1234 

    4.       Check the memory riser for any damaged components. Also, make sure the heat sink clip is installed correctly. Then leave the riser out of the system until step 10)    

    5.       Install a jumper on pins 5-6 of the jumper block labeled “J_DBGCPLD1” which is located near the iSCSI key connector (which looks like a phone jack) as seen below. There isn’t a jumper installed on this block from the factory, so you will need to borrow one from the  NVRAM_CLR/PASS_EN block or get it externally.


    7.       Apply AC.  Wait ~45 seconds to a minute for the iDRAC to be initialized. The front LCD will flicker momentarily and you can see the LCD interactive when it is initialized. The power fault message will be cleared from the LCD message queue.   


    8.       Remove AC, wait for standby voltage to dissipate (10-20 secs or no LEDs visible and no LCD illumination)


    9.       Remove the jumper (if you borrowed from the NVRAM_CLR/PASS_EN block, make sure it is replaced in the proper position) 

    10    . Reinstall memory riser

    11.    Apply AC

    12.    Power up the system 

    Let me know if that resolves the issue.

    Hi Chris,

    Yes, the error happens to start during power up.  Thank you very much for the assistance as this procedure fixed our server.  We were able to boot up as normal!

    Regards,

    Paolo

    Hi Chrish,

    Thanks for the solution.

    Could you please explain what we did by connecting the jumpers to the pin 5-6.

    Thanks

    It clears the NVRam  (Non-Volatile Memory) on the motherboard. Essentially almost like a hard reset.

    I had a similar case in Raiser A, it was solved without problems with this solution.
    Thanks

    Hi,

     

    The R910 J_DBGCPLD1 jumper block location would be here:

    This is only available for PowerEdge R910.
