Add a cell to rp7420

[TeamHP_1]

Hi all,
I added one more cell to rp7420 server but unable to power ON it. I am getting the error "Error attempting to power ON : RtnCodeFailure". Kindly have the attached PS command output attached.

If you tried to power it on shortly after installing it, try again.  the POST process can take a few minutes to complete. 

If the problem persists, review the MP Event Log for any entries associated with cell 0.

Lastly, remove the cell and check the seating of the CPU's.  Improper CPU load can cause unpredictable issues.

Replaced the cell board and now it is working fine.
Thank you all.
