Re: HP ML350 G5 internal & external health leds blinking on front panel

We have four ML350 G5 servers. Two of which are working and two of which are dead with exactly the same problem: both internal and external LED's blinking red and the amber PPM2 LED flashing.

We replaced the PSU and backplane on one of the servers and it made no difference at all. It was still dead with the same problem. When the second server died today with the same issue I Googled and found the following post:

http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/kb/docDisplay/?spf_p.tpst=kbDocDisplay&spf_p.prp_kbDocDisplay=wsrp-navigationalState%3DdocId%253Demr_na-c03562080-1%257CdocLocale%253D%257CcalledBy%253D&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken 

and this lead me to replace the cpu0 processor with one out of the second dead machine we have and bingo! it leapt in to life.

However, it isn't the end of the story as I then took the second processor out of one of the working servers and put it in the cpu0 slot of our original dead machine and it still won't start and still has the same flashing LED's.

What is going on with these servers!
