5.2.4 PCIe slot and Port# assignment

On Linux-based OS each PCIe slot on the backplane has a designated Port number (i.e. Port 0), see photo below.



On Windows OS, it is called Device ID



On Linux OS, it is know as Port#. See following photos.

The following photos are screenshots of Linux OS “lspci | grep 8796” output showing the assigned slot number and corresponding port
number.

Target slot, assigned to PORT #4

Slot 1, assigned to PORT #0
