The 2800 doesn't take the 'P' - it takes the integrated version, which is why it has the motherboard port for the daughtercard and no port for the ribbon connector.
Hi there, I have found many sets of instructions on fitting a DRAC 4/i to the Motherboard of a Poweredge 2800, but none about fitting the PCI version, the DRAC 4/P. I have an R200 at home from which I took it out of as I wanted to fit it to my work server, which is, albeit a dated model a workhorse and being re-juvenised with Ubunutu Server 14.04.1 LTS.  Does anyone have instructions on how to fit it as the management ribbon cable doesn't seem to go to anywhere...
