Hi all.

I have a p550 which I need to install 2 x #5237 proc cards in. The proc cards by themselves allow the machine to boot fine, and all is well. When both cards are installed together with obviously power card installed machine boots through various C1C3CXXX codes and ends up at B150F22A every time. The firmware has been updated to 240_382. Diags run fine, the is no HMC involved, all access is done via ASMI and serial connections for now. I have tried different memory configs and different memory. Even a proc card we have lying around. But nothing will boot system with both procs installed. The system is not partition or use CoD.

Anyone with ideas, please let me know.

Many Thanks

It could possibly be that the firmware is corrupted. You might want to install it again. Just to be sure.

Just a thought.

Hi... the second processor card requires 200 - 240 Amps.. Do you have that?

Hi,

Thanks for replies. Firmware has been reloaded twice, which each of the different procs being installed, in case some aspect of firmware goes to procs. With no effect on fault. The server has the two power supplies installed and connected with power, both 240v.

Still no joy.

Also,

Have tried these procs in a different chassis, ( only common parts are procs and memory ), exactly same problem on that too. Have trouble believing
procs have problem working together, but are fine on their own. Surely must be some setting somewhere to sort this out. Have reset mobo to factory defaults.

Personally, I've never attempted to run mis-matched processors or memory, so dunno if your symptom(s) would match such a scenario..... but seems you've exhausted pretty much everything else.

Thanks for your help, the two fru's on the proc card match. So no problem with speed settings etc, also memory mirrored between procs. So there should be no problem there. Most info seems to point at firmware but, is at latest level and has been reloaded anyhow.

Feeling as though this is really odd.

Hi All,

To complete the story, it turned out although both procs work on their own, it wasn't until two new procs were installed that the system came to life, it was also necessary to reset the server firmware setting on their own ( not part of a full factory reset ) to allow machine to start. Am glad these errors no happen often, many thanks for help given.

Hi,

The problem was to do with the two processors working together, they just wouldn't, although both would work independantly. What we did was log in to the asmi and go to factory setting, then go through each of the bottom two resets independantly, doing the lot together would just hang the server needing power to be dropped.

Note be sure the procs have the ibm mod fitted to stop the pins bending on them. it a white collar with pull printed on it.
