Thank you for contacting Intel Customer Support.
Based in the information you have provided, I would like to recommend the following:
*Try basic configuration: 1 processor and 1 memory module.
*Reset the CMOS: Technical Product Specification [Page 100 / 8.1.1 Set BIOS to default].
*Try to run the latest firmware update: Intel® Server Board S2600CP Firmware Update Package for EFI.Firmware update instructions: Installation and Operation Instructions.
I have encountered a similar boot issue. There are no error messages, no beeps. Status led is green.
I've already replaced PSU, CPU and memory with no luck.
Could you tell me, did you managed to solve the problem?
What is the model number of your Intel Server Board?
Have you tried only the CPU without memory? you should get some beeps.
Thank you for your reply.
The model of the board is Intel S2600CP4.
Motherboard without CPU generates beeps.
Motherboard with CPU and without memory doesn't (no beeps).
Could you tell me whether such a symptom indicates motherboard hardware failure?
The problem has appeared after moving the motherboard to another chassis.
In order to troubleshoot, I pulled the motherboard from chassis, disconnected all devices (pcie/usb), and then:
1) removed and replaced the memory modules (I left only one module);
2) replaced the PSU;
3) replaced the CPU;
4) changed pin to clear the BIOS to default;
I'm still able to login via RMM4 connection, however all available sensors are displayed as green. No error messages in system log.
I also uploaded firmware to usb drive and tried the bios recovery procedure, but computer shutdowns after 1-2 seconds (similarly as in previous situations)
