Hello,

 

What is the PowerEdge Server model and OS you are working with?

 

Recently installed hardware or updated software may cause this exception.

It is recommended to Update or remove the hardware or software.

 

Was anything done on the server around the time this error started?

     Any updates applied, hardware or software added or removed?

     Is there any add in hardware that was not on the original purchase?

 

 

Initially I can recommend these troubleshooting steps and check result after each one.

 

*Update iDRAC firmware and Check iDRAC in the System Event Log (SEL) and LifeCycle controller (LCC) for any related errors.

*Drain flea power

*Clear NVRAM

*Run built in diagnostics

 

 

Confirm or update iDRAC to latest firmware version and check logs for any related errors.

Check results

 

drain flea power (shut down, disconnect power cables and Network cables, hold in power button 20 seconds with cords removed). After flea power drain, system has to set for 3 minutes for DRAC to reset without any power plugged in, then plug in NIC and power but wait 2 minutes before power on to give DRAC time to initialize.

Check results

 

Clear NVRAM - there is a map under the lid to show the jumper location. Shut down, Set jumper to the Clear position, power on and Post up to the jumper error, shut down and return jumper to original location.

You may need to reconfigure custom BIOS settings such as Boot Mode: BIOS or UEFI and other custom settings.

Check results

 

Run diagnostics. Boot to <F10> LifeCycle Controller (LCC) and run the built in hardware diagnostics to test the hardware.

Check results
