Cappilio, The issue you are having is due to the model of the H700. The H700 modular version of the card is actually designed for the Poweredge Blade series of servers. The model you would need is the H700i which is the Integrated version, designed to go in the white Storage Controller Slot you are referring to. The part numbers are KK67X and CNXVV. The last model of the H700 is the H700A which is the adapter, this is the model needed for installing in a PCIe slot.  This link goes into detail in the H700 overview - [URL]  Let me know if this helps.
Hi Guys  Need some advice please, A few weeks ago we purchased a Dell R410. This came with a Perc 6/ir Modular. However when we came to installing disks we noticed that the controller would not recognise disks larger than 2TB. this is not good as we need to use 2x 3TB disks and 2x 500GB Disks in a RAID 1 Configuration. After Googling around, i came to the conclusion that the card it came with the "Perc 6/ir" doesnt support disks larger than 2TB.  So i went ahead and purchased a new Controller a "Dell F2WGY Perc H700 Modular" which apparantly supports larger disks.  the controller arrived yesterday so i removed the older Perc 6/ir Controller from the bottom slot of the riser board and plugged the "Dell F2WGY Perc H700 Modular" in the same location. : Picture of Slot i inserted H700  H700 Card: See Picture Perc 6/ir Card: See Picture  Anyway, once i inserted the card and booted i was presented with the error; "PCIE Training Error" System HALT. Obviously this wouldn't boot any further. So have i brought the wrong card? im confused at the moment between modular and intergrated? is the bottom pcie slot for integrated cards only? I did then add the new card to the Top PCIE slot. the system then did boot and it could see the card. however ti did not find any drives?  what exactly am i doing wrong will this card work at all? or am i out of luck and need a different card?
