Re: Adding CPU's to RP7420

Hi,

attachment has output specific to cellboard. DF command displays the output specific to FRU (field replacable unit) and cellboard & CPU are separate FRUs.

Can you attach output of "DF -ALL -NC" for simplicity?

Re: Adding CPU's to RP7420

There is no new CPU visible.

Did you lock the CPU socket?

Did you connect the power cable?

Hope this helps!

Re: Adding CPU's to RP7420

I did not actually install it but I watched.
All he did was screw down 6 screws and attach 2 pig tales that came off of it into the cell board.

Re: Adding CPU's to RP7420

But the modules are still installed, right?

You need to turn the ZIF socket lock/unlock screw (between the fan blades) one half turn clockwise to lock the CPU into place.


You will see this if you inspect the empty socket.

Hope this helps!

Re: Adding CPU's to RP7420

I just spoke with the guy who installed it and he thinks that the lock is not locked. And he doesn't see a way to lock it through the fan becasue there is a heat sync piece of metal that blocks a hole that you could possibly get to with a long allen wrench. So I need detail on how you are suppose to get the cpu in and locked. Can you lock it then put the cpu in the socket?

Re: Adding CPU's to RP7420

Yes, insert the module into the socket, then turn the lock screw with a special tool.

Hope this helps!

Re: Adding CPU's to RP7420

Ok, but he is telling me that there is no way to get to the lock screw becasue a piece of thin metal on the cpu is blocking the hole.

Re: Adding CPU's to RP7420

If you install a cpu module, you slide it into the slot, lock the slot, fasten the screws.

If uninstalling, you unfasten the screws, unlock the socket, pull the module.

The metal sheet prevents a wrong order (e.g. unlock the socket and bent the pins while the screws are still in place.

A wrong order makes the installation/deinstallion almost impossible.

Tell the guy to RTFM.

;-)

Hope this helps!
