HP ML350 G6 second CPU

Hello,

I have server HP ML350 G6 with 1 CPU E5540. I'd like to add second processor.

Server have 3 fans (2 back and 1 front).

After install 2nd E5540 with heat sink 508876-001 and RAM similar like for first processor server doesn't start. Only fans work with full speed, no leds flash on the system board.

Processor and RAM are good, because I install them in first slots, and work well.

Do you have any idea what can I do to make good start?

Thanks for help.

Hi,

 

Its recommended that BIOS needs to be updated before adding a second processor.

You may also clear NVRAM from the System Maintenance Switch.

 

Thank You!

Re: HP ML350 G6 second CPU

Hi,

I updated BIOS and clear NVRAM from the System Maintenance Switch.

Server doesn't start.

I have 3 fans inside server (2 back and 1 front).

Do I have to have 4 fans (2 back for CPU1 and RAM1 nad 2 front also for CPU2 and RAM2)?

 

 

Best regards

Robert

The ML350 G6 Server Maintenance and Service Guide mentions that both processors need to have the same part number:

 

"To prevent possible server malfunction and damage to the equipment, multiprocessor configurations must contain processors with the same part number."

 

Is that the case?

Did you ever get to the bottom of this? I have a similar situation but with two X5670 CPUs. I have all four fans installed, but I believe only three are required (one is for redundancy).
