RE: Service Processor Functions

Yes - and to add to Larry's excellent description, the FSP also houses
the web server for ASM.  Additionally, there are exceptions which apply
to the 595 model:

* no control panel on 595
* dual FSPs on 595
* on 595, HMC not directly connected to FSP (See latest iteration of
iSeries System Handbook, page 162 - connects through BPC)

Emillo,

  Here is the answer as I understand it:  The SP (or FSP as it is named
on the i5/p5) is running as long as there is power to the power
supplies. It controlls input power to the rest of the CEC as well as all
expansion cabinets. It handles all interrupts enabling shared busses on
the system. It owns the front panel and accepts the input from the
butons thereon. It communicates to the HMC. 

In short, If the Service Processor goes *poof* the iSeries goes, as Al
would say, "Casters Up."
