??? Sadly you are way off. you should read the text again. S1200btl has that function, ridiculous to add it otherwise.
but the other boards do have an extra function that is.
As you self ref to the documentation:
"Figure 69: Serve Health Power Statistics Page on S1200BTL Platforms and S1200V3RP Product Family"
And the extra function the systems based on Intel® Xeon® Processor E5 Family (4600, 2600, 2400, 1600, 1400) have:
On an EPSD Platforms Based on systems Based on Intel® Xeon® Processor E5 Family 4600/2600/2400/1600/1400
Product Families you can see the lenght of time that the statistics have been getting collected.
See Figure 70 for details.
Did you even look att figure 70 to see the diffrent between the board family?
Sadly this cant be the answer i waited for a week to get that i read my self 100 times.
