PCI Power Supply not turn On!

[Arvin E.]

Dear all,

I have problem in my rp7410,
I replace the System backplane and now when I want to power on server, PCI Power Supply LED not turn on!
How can I solve it?
I insert one cell in position 0. When I power on server it shows in VFP cell state starting and after about 350 log it restart!

Thanks in advance

If you have only 1 cell, it should be at position 1, not 0.

Thank you Torsten,
I follow the rules of inserting cpu and memory to cell board, and insert cell in position 1 instead of 0, and now PCI power supply is turn on, and cell joined the partition.
but I don't know how can it be related to this problem.

Thanks anyway.

first cell must be 1, second cell 0

[Arvin E.]

Now I have another problem,
When I insert another cell in position 1, and remove first cell, I get error "PDH_CELL_INFO_CORE_IO_UPDATE_ERR" and server going to restart.

what is it?

[Torsten.]

Not exactly sure, but maybe the other cell has another firmware level installed?

[Arvin E.]

This exactly what I must do, as you said I upgrade firmware two cells now have same firmware and problem solved.

Thanks a lot
