Dell T610: CPU1 Status: Processor sensor for CPU1 IERR was asserted
I have a Dell T610 with two E5645 CPU. The OS is VMware ESXi 5.0.0
I got the following error :
CPU1 Status: Processor sensor for CPU1 IERR was asserted
I had the same eror on a Dell T420 and the dell support said me to upgrade BIOS and iDRAC. I have done the updates and the problem was resolved.
I think so it will be the same solution for my T610, so I have upgraded BIOS to 6.3.0 version and the iDRAC6 to the 1.95 version but the problem persist.
Somebody have a solution ?
Thank you.

Hello claude63
The CPU1 IERR indicates that CPU 1 detected an error. Unfortunately it doesn't tell us what caused the error. The best way to troubleshoot a CPU IERR is to review the hardware /system event log in the iDRAC/BMC. Check to see if any other errors are occurring at the same time that the CPU IERR is occurring.
Thanks

I have the same error on a T610. It started happening when I upgraded the iDRAC from 1.03 to 1.07 and the BIOS was already at 6.6.0.
I've tried removing the 2nd processor and all the RAM and only using ONE PC3-10600R in A1. No change. I've tried switching the processors 1 for 2 and 2 for 1. I've changed processors from X5675 to X5670 to E5520. Still getting the error.
It won't boot at least not to any display and certainly not to CMOS. I obviously can't see any errors on the monitor.
I have a second T610 and I've put the processors and RAM from the first T610 to the 2nd T610 and that 2nd machine boots up as it should.
I'm stumped. I don't know how to access the server to read the iDRAC/BMC.
I'm suspecting a motherboard failure but the only thing I did was update the iDRAC.

Hiya Gary,
Kudos for testing the proc and memory in the other machine. Knowing those aren't related to the problem, I'd recommend shutting the server off, unplugging it from source power, holding the power button down for 30 seconds (performing power drain), then remove the cover and move the NVRAM jump. If you cover the common and far pins, you can clear NVRAM on power up. After you power on, you'll want to move it back, and this will also reset the BIOS to factory default.
