The EPERXP is a B-Side 3-slot PCI-EXPRESS/PCI/PCI-EXPRESS right angle riser designed for a 2U rackmount chassis. The overall dimension of the main board assembly is 2.75"H x 7.09"W.

The top PCI-Express (PCIe) connector connects to a PCI-Express slot on the motherboard behind the riser via a wide cable. The middle PCI connector tie directly to the goldfinger. The bottom PCI-Express connector connects to another PCI-Express slot on the motherboard via a narrower cable. User can order the riser with a PCIe-X1, X4, X8 or X16 and PCI-32 or PCI 64 connectors. All connectors are mounted on the B side of the riser card.

This riser is designed for chassis with three horizontal cutouts that line up with a PCI slot on the motherboard. The top PCIe connector is located at 2.52", the middle PCI connector is located at 1.72", and the bottom PCIe connector is located at 0.92" height.. All height dimensions are referenced to the bottom of the board. The wide and narrow cables can be ordered in various lengths, depending on the location of the PCI-Express slots on the motherboard.

Part Number Suffix Definition:
A sample part number format for the EPERXP is EPERXP-XYZ-ABC-W/N.

-XYZ identifies the bus sizes of the three connector, counting from top to bottom. The X and Z can be x, 8, 4, 1 or 0, which means X16, X8, X4, X1 or no PCI Express connector. The Y can be 8, 4 or 0, which means 64 bit, 32 bit or no PCI connector. For example, -x81 means a PE-X16 at the top, a 64 bit PCI connector at the middle and a PE-X1 connector at the bottom positions. A zero in any of the XYZ suffix, means no connector at that position.

-ABC identifies the VIO voltage selection for the PCI connector or the size of the PE paddle boards. The B can be 3, 5 or 0, which means the PCI VIO is 3.3V, 5V or none. This should correspond to the connector defined in the Y suffix above. The A and C can be 0, 8, 4 or 1, which means X16, X8, X4 or X1 PE size paddle board at the end of each cable. For example, -031 means 3.3V PCI connector with a X16 and a X1 cable attached. This multiple riser allows the PCI connector VIO voltage to be different than the PCI slot VIO where the riser plugs in..

-W/N means the cable lengths associated with the riser. The W reflects the cable length of the paddle board attached to the top PE connector, in inches. The N reflects the cable length of the paddle board attached to the bottom connector, in inches. For example -2/1 means 2" top cable and 1" bottom cable.
