Re: UPS messaging with multiple partitions

Rob,

I think the last thing you want to do is reset your FSP.  That is a last 
resort action only used when the HMC and FSP loose communications.  
While not that hard, also not advised unless you have done it before.  
The FSP goes back to factory reset when you do that.  You would have to 
reset all of the passwords and network communications for the HMC/FSP.  
Again not hard and I have done it many times, but know what your in for 
first.  Also, the "pin hole" is in different locations depending on the 
system.  For instance on a P5 550 you have to take all the power 
supplies, fans, etc out to get at the little dip switch that resets the 
FSP.  That's only one version.  Where is it on your box?  IBM has been 
consistently inconsistent with the location of the reset.    Don't even 
talk about dual FSPs.  I think you get the point.   If that's what you 
need to do, it's best to get your IBM CE to help, or Larry, me, Pete, 
etc......

Was the UPS cable from IBM?  There are a few different part numbers but 
they are all the same cable.  My guess is there was not enough powered 
off time for the change to take.
