Somewhere online, I read that the Intel x520 NIC is agnostic when it comes to transceivers and motherboard interfaces, so my understanding is that there is no problem with the NIC.

Also, people online say that HP hardware is picky. I am guessing that this is due to the HP switch port being SFP and not SFP+ (thus needing a SFP transceiver). I tried flipping the fiber optic on one side as someone had suggested, but no luck. Nothing seemed to happen (the respective status lights did not light up). I tried plugging the transceiver into the x520 NIC and into one of the SFP ports on the HP switch, and I plugged the fiber optic cable into both. In the device manager, I see the dual SFP+ ports as 'Intel(R) 82599 10 Gigabit Dual Port Network Connection,' so I believe my NIC is installed in my computer correctly. It was given to me for free, so I do not know where it came from.

I believe I have an IBM 12R9914 (OFNP, MMF, LC-LC, orange) fiber optic cable.I have a Mikrotik CRS305-1G-4S+IN switch with SFP+ ports.I have a HP Procurve 1410-24g switch with SFP ports.I have an Intel 82599 X520 (dual SFP+) network adapter in my motherboard.
