n4000-65 processor installation

[Shankar_6]

Hi,

We have N4000-65 server with 4*A6687-A processors installed. We have installed 2*more new processors of same type,but could not see from the OS.

Checked in the BCH menu,but could not see the new processor there..cpuconfig command in boot menu works only the old processors..

is there anything that we can check here? or any rules for processor installation also as like memory..?

Points will be allotted.

Regards

Check if the second power pod is installed.

hi,

is there command to check PSM status at OS level..?

I'm not sure - open the first top cover and have a look.

Hi,

Thanks for your reply. I am looking for any OS commands to check PSM status.is there anything that you could help here..?

Hi,

we have replaced the PSM(for CPU0 and CPU2) but still server cant see the new 2*processors..

can anyone suggest what to do now? any known firmware issues or is it due to system board problem or something else..?

Points will be allotted..

You've *replaced* an existing PSM? Not *added* a new one for your new processors?

If I remember correctly, N and L class servers both required N/2 processor power pods for N processors (rounding up).

So if you added 2 new processors, you should have added 1 new power pod too.

Hi,

Yes..that is correct.We installed new PSM for new processors but they were not getting detected. Then we changed PSM ,but still same problem.

Any guidance here would be appreciated.

hi,

so you should have 6 cpu's and 3 PSM's installed.

It is also worth checking you have them in the correct slots and the PSM's are the correct ones to go with the CPU's. There are 2 diffferent rated PSM's depending upon the cpu installed.

There is no OS commands to check the PSM, but if it boots you should be able to see the cpu status at PDC and in the GSP, with power applied.

you should have cpu's installed in slots
1,3,5,7,0 and 2
and PSM installed in slots 1,3 and 0

so looking from the front of the server the two slots at the front left and the front left PSM slot should be empty

Verify the cpu part numbers as well, should all match

Hi,

We have verified all the above..PSM and cpu of same model and installed in correct slots as above..

Anything else we can check here..?
