server PER740 errors

Moetariq,

I would start with taking the R740 to its minimum to post configuration, which is remvoing everything from the server, internally and externally, except the following;

• One processor (CPU) in socket processor 1
• One memory module (DIMM) in socket A1
• One power supply unit
• Right control panel and cable (for power button functionality)
• System board

Now if the server posts under the minimum to post configuration then I would power back dowwn and individually add the remvoed devices back one at a time in order to identify the device causing the issue. 

let me know what you see and if this helps.
