Yes sir, the Enterprise needs the Express to be present to work. The part numbers are the same part, just different sources.
I am looking to purchase an IDrac6 Enterprise card for a T310. Using Dell's website I cannot find the appropriate part so I am forced to look at resellers that appear to sell them.  The problem is that they quote different part numbers K869T and J675T. The images appear to be the same. What is the difference between these two parts ? Which one is most suitable for the T310 ?
iDrac6 Enterprise for T310 K869T or J675T ?
