IO Board

IO board for Xeon and dual Xeon System Host Boards.

Part Number: OSS-ACC-IO-0

Product Features

Two DB9 serial port connectors on the I/O plate
An I/O plate mounted PS/2 MiniDin connector supports PS/2 keyboard and mouse operation
On board headers for parallel printer, floppy, mouse and keyboard

The IO expansion board connects to the controlled impedance connector (P20) on the OSS-SHB-X or OSS-SHB-2X system host board to complement the advanced USB and SATA I/O capability of the SHBs. A combo I/O plate is provided with the IOB30 as shown in the side view drawing below. This plate attaches to the SHB using the connector hardware and the OSS-SHB-X or OSS-SHB-2X mounting tab shown in the front view drawing. The IOB30 is secured to the OSS-SHB-X or OSS-SHB-2X using the provided standoffs and IOB30 mounting hardware.
