Hello.

System E1234 error is indicative of memory riser power failure that may be caused by either the DIMM(s) on the riser or the raise itself. The first thing you do is to power down the server and reseat the riser and associated DIMMs. However, it is also possible that it could be a system board issue. Have you done any troubleshooting to truck down the source of the error?  

Just replacing the system board may not solve the problem. You might consider swapping the riser and when the error follows the riser; swap the DIMMs as well. This will point you to replacing either the riser or DIMM(s). But when the errors stays in the same riser position, then it could be a system board issue.

Hello.

Now that the system is not coming back on, drain system flea power else use minimum to POST components below to isolate the problem.

  • Two Processors to POST and boot to DOS or OS (can use one installed, but system emits an error message for improper CPU configuration and will not hand off to boot)
  • Two DDR3 RDIMMs in Slots 1 and 2 of Memory Riser_A
  • I/O riser installed
  • One power supply
  • 2.5" SAS backplane (4-drive or 16-drive) installed and connected to system board
  • Control panel connected to system board
  • Power Distribution Board connected to the power supply and system board

Ensure that all USB devices are disconnected including the keyboard.
