EEERXB16 is a three slot PCI Express X16 right angle riser card designed for a 2U rackmount chassis. It can support up to three independent PCI Express X16 buses. The main riser board is designed to plug into the 6th slot on the motherboard.

The middle PE-X16 connector connects directly to the riser's gold finger. The top and the bottom PE connectors are connected to two other PE buses on the motherboard via two flexible cables. All connectors are mounted on the B side of the riser card. The bottom connector sits on a add-on PCB, which protrude about 0.062" toward the B side.

This riser is designed for chassis with three horizontal cutouts that line up with the typical slot 6 position of the motherboard. Any of the PE connectors on the riser can be configured to X1, X4, X8 or X16. The connector centers are 1.08", 1.88" and 2.68" height. The cables can be ordered in various lengths, depending on the location of the PE slots on the motherboard.

The overall dimension of the main board assembly is 2.91"H x 7.10"W. All height dimensions are referenced to the bottom of the board.
