*xx is the XSB number, in the range of 00-15. \ xx is the XSB number, in the range of 00-15.

d x is LSB-dependent, and is assigned a value as shown in TABLE A-2.

Internal Devices on the M8000 and M9000 Servers

The IOUA is a PCIe Host Bus Adapter that provides access to internal devices when installed at specific locations. The IOUA contains two 1Gb Ethernet ports on the card (“on-board”). When the IOUA is installed at specific locations, it also provides access to storage located on the IOU, as well as platform DVD/DAT resources at the locations shown in TABLE A-7. In the PCIe device path, x is LSB-dependent, and is assigned a value as shown in TABLE A-2. xx is the XSB number and is in the range from 00-15. nn is the number associated with the PSB to which the DVD or DAT device is attached, as further explained in the table footnote.
