They are one over.Insert the Ethernet Card straight down in the expansion slot, lining up the Locating Notches at the bottom of the Ethernet Card, with the Locating Lugs down in the bottom of the expansion slot.You also have to slide the 'tang' at the bottom of the Ethernet Card's metal bracket, down into a space in-between the outside metal framework of the computer case.Plus line up the bracket's locating hole, (half-moon?), with a short dowel in the metal framework.All of the above will become apparent once you start to install the Ethernet Card.One last procedure is to Physically push down on each Ram Memory module ('Stick'), and also make sure the Locks at each end, are up, and in place.Ram Memory gets bumped real easy. Better to check before going on. (Visual inspection will Not do. You have to physically check)Card plugged in, and fastened down, close the computer case.Reattach all cables if you disconnected them.Plug the computer back into power.Plug the Ethernet cable into the Ethernet Card.WAIT 1 minute, turn the computer on.For additional questions please post in a Comment.Regards,joecoolvette
